I installed a resonated x pipe first as I did on my v6 with shortys and mrtv2/s but it helped only a bit with these loud mufflers. I have durakool insulation in the trunk, 2 layers, one glued the other in the shape of the carpet and is removeable, and helped only a bit around town but none at freeway speeds so dont waste time with insulation with loud setup other then for speakers. The J pipes killed it all so dont waste time and money experimenting like I did!
to all thinking about them just have a muffler shop due it.I used 2.25" pipe as I have the 2.5" piping on the car.Gave them pics of Solos and others and let him do the rest. He even made them adjustable with band clamps and a 2.5" dia x6" long end cap. All told $150 for everything.
