looking forward to a little more power/sound....

Thank you Sam for the time you spent with me today walking me through all of the available options...
You're welcome pal I enjoyed our conversations and I can't wait to work with you and get it dialed in. You're going to love it and the fact that it's modular gives you all the options you need!

The Cobb Accesport arrives this afternoon, looking forward to loading the initial tune.

Unobtainium Welding. All bespoke 3.0" built to order exhaust. Can be built SS, Ti, or Inconel hybrid versions. This one is set up with top of the line 5.2" German HJS/Emitec Motorport 100CPI race catalyst and also with 3.5" cat bypass pipes. The Motorsport catalysts provide zero restriction and flow just as well as bypass pipes. With the catalysts we dynoed 621whp, with the 3.5" bypass pipes, 622whp. Have your cake and eat it too... I've tried just about all the major brand exhausts out there, some of which are very good. This one is my personal favorite as it sound like an angry Cup car yet remains 100% drone free due to the proprietary anti drone resonators. Unfortunately these take several months to build and not an option if you have to have an exhaust now..

Thanks for the info. Yes I'm familiar with his work and it is excellent in all aspects. The anti drone tubes are a great feature. I have used them on different applications and they work great. Hard to believe the difference until you experience it first hand. Very nice exhaust if the customer can wait

You're absolutely correct. The difference is unbelievable until you experience it first hand. I've tried and heard just about every exhaust out there for these cars and none even come close to the lack of drone the anti drone tubes give you. You simply do not need any mufflers on the exhaust whatsoever.

The flybys are with the bypass pipes which I'm running now as the car no longer sees any street duty. The bypass pipes are 3.5" and the rest of the exhaust is a flow through 3.0". There is actually no difference in sound between the bypass pipes or the Motorsport catalysts as the cats simply do not provide any restriction due to their large diameter.
