I would definitely check out doing our X Pipe 200 cell Sport Cat to go along with the mufflers, you will love the sound and power increase. Its a simple bolt on replacement and it doesn't effect emissions, warranty and No CE lights. We have Dyno tested them versus our 1st generation cross over Cats that we used to make and they made a big HP increase over them, so it will really wake the car up over the stock cats. PM me if you have any questions and if you decide to do it, I will make you a nice member deal on it.
Thanks

 

Did the "Gundo Hack" and installed that AWE crossover pipes (used) to eliminate the center muffler. Not sure if the cost of a complete cat-back system meets the bang-for-the-buck to HP ratio, but for less than a few hundred bucks I got the sound I was looking for.

BTW, if you live in NC I can recommend a great muffler shop in Raleigh that does excellent work for a great price.

 

Thank you all for the help. I'm going to take the first step with 2" Gundo at Provost Motorsports in NJ. They are my local PCA shop and I've worked with them on maintenance items. (We hold PCA events there too.)

We'll see how this nets out. I might have to do the fabspeed mod as well if the Gundo doesn't get me where I'd like to be.

 

Good luck! Let us know what you think.

 

Do the cats, they are the best exhaust mod you can do.

 

if we speak of performance per buck on '06 car - X51 headers + any 200 cell cats + softronic flash. mufflers do not change much/anything power wise.

 

AWE cats.....a must

 

I have the Tubi exhaust it sounds better then stock but the is no performance increase as far as I can tell.

 

I received some recommendations to go to mufflex in Hamilton NJ. They work on many exotics. The full bypass job with stainless 2" is $250.

 

Can anyone explain the difference between crossover and x-pipe 200 cell cats?

 

+1 for Fabspeed.
I have the Maxflo muffler on my car and it is superb. Highly recommended

 

Anyone know of someone in Denver that can do the Gundo hack? I want it!

 

the Gundo hack looks like the way to go!

 

When the times comes, I'm going with the Fister. It looks like a "professional" gundo type hack.http://www.fdmotorsports.net/index_files/Page732.htm

 

Lots of choices. Better to find a "match" of you P-car; 997.1 or .2; and go to a local Porsche club events and listen to them live or meet a fellow member through this forum / or local shop and do the same.
