Message	They definitely give your exhaust a deeper sound...very cool! They was also a noticeable increase in HP. The downpipes did increase my EGT and also increased my boost by 2-3lbs. You definitely need to take that into consideration if u r already maxing out your boost, injectors, etc.. I went to a colder plug to help my EGT's but didn't help a whole lot as far as that goes. Not sure what the dyno would tell. I had my Z dyno'd after I did all my bolt ons. It pulled 330 to the rear wheels w/371 Ft. Lbs. of torque. Not to bad I guess. I thought it would do better. In HP add-ons I have the cat back exhaust, GD split flange downpipes, & JWT ECU w/boost jets.
