I chimed in on another thread and should have started a new one so here it is . No dynos, just wanted to provide so info and maybe another alternative.

System is made from full 304 stainless to prevent rusting. The part features flex pipes to allow easier installation and extra movement from the VQ35DE engine. This is a great upgrade for those who want a bit more power while still keeping emissions in check.

There is a lifetime warranty on this part from OBX.
