I know I have an exhaust on order right now. Some like to hear before buying and then make a choice. I lke to hear before so I can find out what sound I going for. I know that what Tony and Fast Intensions makes is top notch but you know what I mean.

We might possibly be able to accommodate to Sedan crowd. I am actually getting ready to come out with a revised version of our Sedan cat back. The new style X Pipe and an oval tip that is a little more streamline with the cutout.

this sounds to be a good idea. i should do this when i go supercharger and the the MXP catback

Charles you might lose power doing that if you go SC.

More flow more ballz for turbo

More Flow Less Ballz for SC

When having turbo, new headers new test pipes 3' is a good to go for more ballz
For SC changing those and having more flows will make less power

Back then when Sam tuned my sc g35 he told me that if I had stock headers or cats I would've squeezed out a little more power.

^ huh?????

Having a more free flowing exhaust will produce more hp with a supercharger vs n/a.

Say LTH and an aftermarket exhaust frees up 20 whp n/a. That same setup vs stock will free up more than 20 whp with a supercharger.

With Forced Induction, you want to reduce back pressure as much as you can to help the engine breathe out easily. The easier it breathes, the more numbers it'll put down since the engine doesn't have to work it's azz off to get all the exhaust gasses out.

Kind of like when you're jogging, you exhale from your mouth since it has a much lower back pressure than your nose, try exhaling from your nose and it'll be seconds before you're exhausted and you'll go into limp mode haha

I did read on Stillen SC development thread though that they'll be offering pre-tuned maps to go with stock headers, HFCs & Catback. That's why they advised to stay away from LT Headers since adding those (without a tune) will lean out your SC'ed engine and that's basically asking for trouble.
