Track sound restrictions are the only reason, and I miss that exhaust every time I hop in my car. Even out at Thunderhill I was getting flagged. The combo with the race headers sounds amazing (constantly had people coming up to me and talking about it) but it is very loud! Running with the valves closed would sometines get me by, but that's not a long term solution because eventually that could cause them to fatigue and break. I went back to stock mufflers for a weekend which promptly split open at the seam and melted my bumper. I'm using a Milltek resonated system, now, which is certainly far quieter. Not sure I can fully recommend it because I had pretty substantial fitment issues with both systems I was sent. One was unusable. I'd have the Top Gear back in my car tomorrow if I could.

Definitely come say hi if you see me out!

It's one of my favorite mods. That and the shifer are things you interact with constantly and make a big difference in the driving experience. With the modern steering wheel the 987 interior holds up surprisingly well!

I was looking at trading my mazdaspeed3 in for one but they're atleast 30k with 60k miles on them. Crazy lol

Yes I installed an OEM center rad. Need is a tough call, depends on your climate and how you drive, but it certainly is not going to hurt adding some cooling capacity. Keep in mind our coolant keeps the oil temps down too

It's a Getty Design Interseries 60" wing with tall uprights.

@@PeterSierraRacingSupply Thank you!

Tightest part would be at the shoulders, mine just barely touches the door card. I think it would probably be doable if a little tight!

I did, and yes relatively safe. Pretty common among race tunes. Of course I'm sure it does stress the engine more, I tend to only rev it all the way out on track with a mixture of 100oct in the car.

California keeps getting more and more strict on sound. With catless headers and the Top Gear catback I kept getting flagged, some tracks I could pass valves closed, but that stresses the system and can damage it over time. Went back to stock for now just to remove the headache from my life, but then my stock mufflers busted open at the seam and melted my bumper haha. I'm testing a new, hopefully much quieter system that I may also add to the lineup alongside Top Gear if it goes well.

Absolutely nothing wrong with the top gear system themselves, I wish I could still be running mine! Sounds incredible and nothing but compliments from everyone but track officials haha.

@@PeterSierraRacingSupplymakes sense. Thanks for the reply. I’m curious to see how it goes with your new system. I’d like to go catless for the extra power but want to make sure the rear muffler isn’t too loud

@@chipattack912 I got the resonated MIlltek system in the car recently. Sounds pretty good, at least from the inside! Far more subdued than the Top Gear system + catless headers. Hopefully I can get out to the track in the next couple of months and get a video. Would be nice to get some footage outside the car, too. Quality-wise, the Top Gear is definitely nicer, with much better adjustment for fitment too. The Milltek was a real nightmare to get installed. Still not perfectly aligned, but good enough.

Yep that's a common issue for sure, especially stock. There's a lot that goes into it, but getting a proper track alignment is critical. Lower control arms are needed for the front to get enough camber (plus potentially a few other parts depending on what settings you want, exactly). Additionally, I highly recommend Tarett GT swaybars. Once you have good alignment settings they can be used to fine-tune your car's balance. I currently have mine set to full soft in the front, and one step from full hard in the rear. This allows the rear to rotate far more than stock. Lastly, learning how to trail brake effectively really maximizes corner speeds and laptimes. Inherently we have a lot more rear than front grip with the weight balance and wider tires at the back. When I get the trail braking right I can carry WAY more speed through the corner.

@@PeterSierraRacingSupply Thankyou for the insight. I have a rear 22mm rear sway bar incoming. Would installing just the rear sway bar ( and oem front) be enough to get the car rotating better? Cheers.

@@BlitsBB Tarett bar? It'll certainly help. Defininitely look into adding more camber and balancing out the alignment as well.

Not a noticeable amount by the butt Dyno anyway. Without a tune and with headers I pulled on a 981 S, too. There's a shocking amount of power available in these engines with headers and a tune, though. Porsche really neutered them from the factory!

Not possible, back pressure being needed is a myth

Data was showing that was where I made up all my time on Vimal's 1LE! Felt planted through that section.

@@PeterSierraRacingSupply yap, you have so much more grip on that sector compare to the heavier cars

@@mcbat8 hes so planting in the turns and corner exit ruclips.net/video/Kaa-_gB33DA/видео.html

@@APEX1LE you guys are very fast between T8 and T10. I think I need to send it harder there.

These are non-catted race headers, and the standard (non-valved) exhaust is about equivalent to valves open. The valves shutting just quiets things down.

I lost a good half a second at Phil Hill too. It'll come with more practice! Just needed to put something together before it was 105* out haha.

Is this Top gear exhaust on this car? Sound good 👍

A couple times! Just on a whim never asked anyone to do it. Getting the car through Turn1 from the would be pretty cool.

Or down the corkscrew next time I'm at Laguna!

Thank you! Yeah that missed shift hurt haha. Plenty of time left on the table with some cool weather and cleaning a few things up.

This track is pretty smooth, so around 3 clicks front 5 clicks rear.

Thank you for getting back to me. Hopefully I see you at an event one of these days love to checkout the car

Sorry just to clarify the 3&5 clicks. So zero being the lowest and 25 the stiffest the front would be 2 from the stiffest and rear basically at 20 from zero.

@@keithkashevaroff4987 definitely come say hi if you see me! Starting from full stiff, so fully turned in clockwise, back it out 3-5 clicks.

Ok thanks. I’m running the NT01 and I usually try to keep them about 34 all around hot. Is that a good temp for the cayman or do you like them staggered

It definitely wasn't a great mic setup but the turbo also quiets things down quite a bit. My N/A 240z is louder but doesn't make all the fun turbo noises!

Yep I think a double apex, or at least keeping it right near that second curb works well. Catalyst shows me that's the fasest way I've taken that corner thus far at least! Yeah 10W can be a brutal corner on tires I just keep it as wide as I can through there. You've got 7, 9, and 10 one after another which really work those front tires hard so it's not shocking to get some understeer there. These RT660's I'm running now are good for 2-3 laps at their peak grip so I'm not pushing hard much past that.

Conner you have the red Mk7 Wagon right?

@@johnzhu5735 yep, that was me!

Yeah definitely, especially T9. Carrying more speed than I was used to.

Haha oh man you trust me in the Tesla huh? I bet these two cars couldn't be more different to drive on track.

@@PeterSierraRacingSupply Well, I'm not saying to push it to 100% lol.

Thanks Max! I'll keep an eye out for you at the track, would love to check out your E36. Have definitely thought about building one for a dedicated track car at some point. You're putting down some stupid fast times.

Haha it might happen at some point! Just need to get more comfortable being on camera.

The more I use it the more I like it. Not so much for the in-car coaching, I find that is hit or miss depending on how much data it has. Being able to pull the tablet out of the car and review each corner individually is huge though. No messing about with data or video from other sources, it's just quick and easy. I was working on improving my speed through a few corners at Thunderhill a couple weeks ago and it was very helpful. No way I'd have improved as much without it.

@@PeterSierraRacingSupply Thanks, planning to buy it for this season.

@@west1785 it's a great tool. Some people expect it to magically make them faster. The analytics it gives you are sometimes pretty good but I think it's much more useful for manual reviews.

Yep it has a handful of mods! Stock you just can't get the camber needed into the front. Full mods list in the description but I have front LCA's which help a lot. -2.8*F camber at the moment. Tires are NT01s.

Hi Spencer. A few things, mainly budget, streetability, and ease of use. The Ohlins are a better street coilover and are single adjustable. At the time I wanted simplicity and to still be able to use my car comfortably on the street. As my track time and car development has gone on, I've certainly wanted more performance-wise and will probably move to a higher end track coilover in the future. The Ohlins are very capable on track though and a huge upgrade from stock, so I really have no complaints for what they are.

@@PeterSierraRacingSupply I see, yeah as much as I’d like an uncompromising setup, I do street the car. Maybe I’ll just wait until I have a beater to go in on that.

@@PeterSierraRacingSupply another question - it seems like the topgear valved exhaust is basically like a soul valved exhaust, at a much better price. Is the street header also the same design as the soul street header, or is it a unique design? Looked different on the site

​@@aisu8481 The Ohlins ride great on the street, better than stock IMO. The track performance and feel isn't even comparable to stock if you're really pushing it. You can totally do JRZ's and still street drive the car, but they're more expensive and definitely more of a compromise for a bit more performance. The longer I own the car the further I head down that road though. Aero coming next shortly. SOUL has many of their products manufactured in the same facility as Top Gear. For the ones that look identical, those were actually originally designed by Top Gear in the UK. It does look like SOUL has changed up their 987.1 headers slightly, but the flanges and such are the same, so looks like they're probably still manufactured in the same spot. There are typically some minor differences between the two companies products, like finish and other small things, but otherwise very similar.

@@PeterSierraRacingSupply makes sense, I love the way the stock suspension on the spyder handles at low speeds, but it could use some more stability on high speed stuff. Anything with a small hill or lump makes it act out. No doubt I’ll upgrade at some point. Haha, it’s hard to keep from traveling that road! I guess the question is, skip to balls-out race spec, or enjoy the journey? Gotcha, I noticed soul has that fancy finish and the cool little soul badge on the valved system. It’s not an extra $1200-cool, though. Bear in mind mine is a .2. That was the one they seem to have longer tubes and a later join, for the catted system (in the pics). Do you have any footage of the topgear catted headers for .2 S?

Lots of different tools to gather data available about there. Currently I am using my phone with the TrackAddict app connected to a Bluetooth OBD2 reader and Bluetooth external GPS for better accuracy. Overlays are done on a PC in a tool called RaceRender.

It's a great system! I'm a dealer for TG exhausts, check out my prices when you're ready to buy.

@@PeterSierraRacingSupply took a look! The prices are reasonable (much better price than Soul or Fabspeed 🤢) Is the valved exhaust a straight-pipe when the valve is open, or does it still utilize the muffler?

@@aisu8481 I'd say they're the best value for these cars which is why I carry them. It doesn't seal off the muffler, no, so some exhaust still goes in. It does open up what is essentially a straight through section, though.

@@PeterSierraRacingSupply I see, so when they say open they mean everything open, makes sense. I’ll definitely be looking at this one. I’ll order from you if I do get it, because you’ve been helpful and responsive

@@aisu8481 reach out anytime if you have any questions I can help with. Whether or not you buy from me I'm happy to help.
