Right now my setup is 3 inch off the stock y to a 90 that exits infront of right rear with no muffler. My ? is have I lost all my backpressure by doing this and if so what is the loudest muffler that will give me backpressure? Will a summit glasspack do the job? All comments appreciated!!!
maybe...never used a glasspack... something like a flowmaster 40 series or those mufflers moze had were pretty sweet. anything will work really

Do the cats do the job or is it worth it to spend $40 on the glass pack?
Naw, skip the cats and do a muffler...
Back pressure? We don't need no stinking back pressure!:D
Only put a muffler on if you want a different sound.
