Check out the RS*R USA website...they seem to have a few more distributors listed. The MSRPs they have listed for stuff really isn't that steep either. I've personally been thinking about those RS*R Race springs....stiff!

I was thinking of getting custom 2 1/2 to 3" piping done, punched cat, headers and a good muffler nothen cheap till i'm ready to go turbo.

Dual N1's are WAYY too big for NA...you want SOME exhaust velocity...big pipes mean slower exhaust gas velocity, especially on a stock engine, and you want such gasses exiting your engine as quickly as possible.


I have the A'PEXi N1's and have ran against other 240's with smaller diameter exhaust systems. I wouldn't say that it is WAYYYYYYYYYYYYYYYYYYYYYYYYY too big. The single N1 is bigger if you want to get nitpicky. And my car is running VERY good even with the WAYYYYY too big piping. I would recommend it to anyone without flinching. I don't believe I really lost any power. Just my .02 cents though......:icesangel

The dual piping design is specifically made to help keep exhaust velocity at midrange rpms.... the low end you loose is negligable to the huge frickin pull you get in the high and mid range...

On a similar note, most of the guys with this size of piping want to go turbo in the future, this means that buying the larger piping now is more cost effective then buying one exhaust selling it then buying another....
