Lowering and rerouting exhaust?
 I just noticed that my headers drop way below my frame. I was hoping to lower this thing 4/6 static and now I am not sure that I don't have to rearrange some of this... What do you think? can I just not lower it as much? and if so... how much?

Re: Lowering and rerouting exhaust?
Have a 4-6 drop and all of my exhaust is above the bottom of the frame.

Re: Lowering and rerouting exhaust?
I put flow master shorties on mine. Gained me about 5" ground clearance compared to the long tubes I had on there before

Re: Lowering and rerouting exhaust?
Have any of you used Summit Racing's shorty headers? http://www.summitracing.com/parts/sum-g9014
I'm not sure if I will lose power or night. At the moment I am running 1 5/8" primaries, 3" collector and my exhaust is full 3" with "H" pipe into Flowmaster 1 chambers.
