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? |

Just one quick question.. would putting on the bypass change the power delivery if I remain on the stock ECU? Such as more lag etc? I experienced a change when I put on a 3" exhaust on my previous turbo car.. but not so sure about a NA car like the GT3.

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....

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:D

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! |

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?

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.
I'm sure Shark will chime back in and confirm or correct. Speaking of wheels.. what about Champion RS171? |
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.

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. |
