Hmmm, bypass pipes would be nice. Great idea. Keeping all the tuned portions on and just adding a small escape route. That's basically the same thing the 993/996/997, etc. fister mod is and I love it on my 911. To me its the perfect sound. I have no idea why i didnt think to try that on this car. lol.. And its SUPER cheap! (As in like $20.00!)
This is how it looks on those cars. Basically same thing.
