    Lose the cat., put in a test pipe. Chances are you'll melt the catalyst and end up with a plugged exhaust, if you're looking at a bigger turbo and most likely fueling adjustments.

        He is shooting for the 425-450 whp mark. IT is allready really quiet for a 3 inch exhaust, I don't think it would be much louder without a cat.

          Pressbent?

          At first I did it for fun, then I realized I made the investment and had to do it!

              So then it's technically 2.5'' since 3'' pressbent corners flow like 2.5''.

                  Yeah, it looked like it was mandrel bent, but I always thought SLS was the only mandrel bent shop in town, so I didn't even look that close at it.

                    press bent looks like a cambels soup can when its bent, all ripply and shit, mandrel looks like u would think a pipe bend should look, clean and somewhat uniform.

                      Yeah, it was very nicely done. It was NOT pressbent then. He said it was ~$200 less than he got quoted at SLS, but he got a discount.

                        Well with an in house mandrel bender, you can move stuff quicker. But i guarentee that Nicks welds are better than the poop they do at exhaust pros. Spanish-Rice shoul dpost up a pic of his sweet downpipe they made him...

                          I wouldn't doubt it. He got what he paid for, but it was what he wanted.

                              Measure the inside diameter of a pressbent 3'' pipe. The flow is only as good as the smallest portion....

                                  No where did I say it wasn't 3''. I simply stated it was "technically 2.5''" since the 3'' pressbent flows like 2.5'' Mandrel. This is irrelevant because we already came to the conclusion it was mandrel bent, therefore it is full 3''.
