Do you think that this mod will void the warantee?

Looks really nice. How does it work with the lower plastic sheild under the engine? Will it melt it as it does not have a heat sheild?

What have you noticed as far as performance? Low, mid, high gains/losses? Let us know. Thanks

If I were you, I would wrap, paint, and/or jet-hot coat the Borlas. The heat they lose will affect overall power and especially spool up. Exhaust gases carry two kinds of energy to drive the turbine wheel- heat and inertia. Thanks to the ideal gas law, when you lose heat, which the bare stainless steel of the Borlas is notorious for, you lose energy. You lose energy, you lose turbine power. However, preventing this heat loss may indeed result in power gains, though I don't think the Borlas look much better than stock as far as bends and the collector configuration.

dude, why are you messing around with headers when everyone knows that INTAKES are where it's at. the shorter and fatter the pipe, the better. once you finish that you'll want to move on to a huge FMIC and at least 4" exhaust.
