SharkWerks GT3/GT3RS Muffler Bypass Released (with videos)
#151
No. If you remove all the mufflers and go full straight pipes you might experience a noticeable torque loss in the lower RPM's as these n/a motors are very sensitive to back pressure, exhaust pulses, etc, but you wont notice any improvement or decline in performance with just deleting the center muffler. With the exception of being able to constantly hear one of the greatest noises know to man!
That's comforting to hear. In the promo vids, I also noticed the exhaust would gurgle and pop upon the lifting of the throttle. IMO i prefer a clean smooth sound.. does the gurgle happen everytime you lift?
#152
It depends on the load and RPM but yes you will get more gurgle and pop. You're the first i've heard of that doesnt like it...? I love it!
#153
There's literally no difference in routing/back pressure the way we did ours so it's not like you need an to do an ECU nor will you loose anything down low. We worked with EVO to get software done for it but it's not "required" or anything. We're dealing with an NA car here vs a turbo car so it's completely different There's no change in throttle response/low-end torque etc... by changing out to the center bypass. It's still being routed just the same as it would via the factory unit except that you don't have all of the surrounding muffler/chamber....
#154
Actually the stock set up with the sport button pressed can induce that too... it depends on what you're doing in terms of driving (letting off etc...). If you drive normally then it won't really do that but if you back-off the throttle quickly/suddenly and aren't warmed up etc.. you'll see

Cheers very much Colby!

Does the significantly extra cost of the full system actually produce significant gains or it's marginal to a certain degree?
I chose wrong exhausts for my previous cars and it really taught me a lesson to do my homework.. so your advice would be much appreciated thank you!
#157
Cool.. thanks for the insight. Btw, could you tell me the advantages/disadvantages (if any) about upgrading to a full system (header back) like Cargraphic to a simple muffler bypass swap?

I'm sure Shark will chime back in and confirm or correct.

These motors are extremely efficient and trying to get meaningful hp out of them is pointless and lots of $$$$$$$. I'd say at best with a proper tune and full exhaust you may get 30 hp and that will run you close to 10k. Your money is much better spent else where, like safety equipment, lighter wheels, track time, etc... And with those, you'll notice increased performance in more than just the straights (ie: cornering and braking). Especially with lighter wheels and losing significant weight (~150lbs). If you want a lot of hp get a turbo or GT2.

Speaking of wheels.. what about Champion RS171?
#159
Excellent wheels! I had the RS98 wheels on another car and loved them. Most of the GT3/RS cars here are running the Sharkworks Bypass and I don't know anyone who wasn't blown away with the sound.

Really good/strong/light wheel. We had similar Champions our Cayman S.
#161
Great choice! Of the Champion wheels the 171's and 98's are my favorite. If they made them in 18 I would already have a set. If you're going to track the car though, get a good set of 18's (BBS E88's or Mags, CCW C10-C14's, HRE C-series, or any Fikse Profil)
That is one bad@*** Cayman! How would that thing hold up against a stock 6 GT3 on track?

You couldn't have asked for a better deal!

if you want to add power to gt3, buy a turbo, it's much cheaper that way.
if you want to lose wt on gt3, rip everything out just keep the seat and steering wheel. the instrument pod and dash are all dead wt as well.
if you want to lose torque overall, use aftermkt header and straight pipes.
if you want the car to sound like it's on steroids, install shark bypass. it doesn't drone.

Hey Colby, thanks and it was a fun/fun car... It's not as raw/involving I think as the 3 but it's a blast to drive in any situation and so well balanced. Great chassis!
