WHat are the differences in the dual and single other than the obvious tips?  What r the benefits of each and the draw backs of each? are they both N/A and turbo capable or is one better for a certain application than the other?

I think the difference in piping is 2.75" to each pipe on a Dual vs. the 3.00" piping on the single.

I think the Dual is supposed to give a little more mid-range power than the single. Someone correct me if I'm wrong.

Actually, the single is bigger than 3"...its 80mm...(found this out after measuring the gasket to get a piece to replace my pre-muffler...it's more like 3.25-3.5 in).

The N1 Dual will retain more torque and get about the same HP gains. Since its split into 2 pipes, you get more back pressure that with the N1 single, therefore you get more torque, which gives you a little better midrange, with very little top end difference from the single.  The N1 Single would be best suited for a turbo. The dual would be a better N/A settup.  But both would work fairly well for either.

And it looks nicer. :biggrin:

But Irena anything with your name on it and everybody looks 8)  .Thanks all!  I guess the dual will still be worth it if I go SR also huh.  I like it better anyway.  Thanks again.
