BEFORE ORDERING: Lead times on the batch of downpipes is 1-2 months and will ship directly from us to you.  Not for sale in California or New York, due to emission laws. 

Our patent-pending Evolution 2N1 downpipe is almost ready for another batch shipping.

This combo replaces the highly restrictive O.E pre-cat with a free-flowing, contoured, hand-welded and full radius 3.0" tubing. The upper factory heat shields cannot still be installed, but we will be testing the PTP downpipe blankets, which we recommend.

The entire assembly made of high-quality 304 stainless steel and is TIG welded by our master welders in the USA.

The thought with this downpipe is to be 100% EPA legal so you don't have to buy a catless downpipe. You can swap out the catless portion at the track for racing events only, and return the catted portion, within 5 min., with our V-band clamps to make it extremely easy.

This downpipe works with OEM front pipe or also 3" aftermarket front pipes.
