I know this question gets repeated quite often, but I searched and found basic installation tips.

My questions are:
1.What is the best exhaust setup for a whipplecharged 6.0 LQ4 with ASM longtubes?
(no cats w/ muffler,cutout after the cats,cutouts after each header)
2. What size of piping if muffler is kept on?

THIS IS FOR A 2000 RCSB

 

Anyone?

 

well your forcing more air in there. best to get out as much as possible the way i see it.

so, what about dual cut outs.
