I already have a Stillen y-pipe and am wondering if I would get any gains from a high-flow cat plus a B-pipe but keeping the stock muffler. I do not want my car to be loud unless I am getting on it but I want more power. Do these exhaust mods work with a stock muffler?

 

You'll be fine. The muffer only gives gains of about ~1-2hp of a n/a Max, so basically the only reason to go aftermarket muffler wise is for looks/sound.

 

Go for the 2k+ Maxima muffler. It will give you an amazing throaty sound and I can only assume there is some gain from the muffler. I love mine.

Is there anything you can do about that odd wrapped double tip of the 2K mufflers?

My 2k2 muffler doesn't have a throaty sound.. =( Maybe at idle when I first start the car. But I really don't hear it otherwise. Could be the intake dorwning it out though.
