should sound good, prolly really loud. i had a 4" round magnaflow muffler on and it sounded sooooo good but was too loud with my 1 1/2 year old, too much drone

I know Alabamaguy had some spintech afterburners on his for awhile maybe he could post some videos of them. He posted them one night for me and I liked them but I don't think they are super loud but queit at normal speeds but get louder at WOT.

ls4 in a rwd????

also OP, with the 4" round magnaflow it sounded almost like a vette kind of sound, LOTS of tone and loud with very little rasp.

doesnt make any since to me, and LS1 would be a wayw way way easier / less expensive choice to do a transplant, and make way better gains. would have to make an adapter for the trans, what about the motor mounts?

I have a spintech pro-street. Love it. That being said, if you could somehow record an obese man taking a dump and play it in concordance to your RPM you would have a better sound than a flowmaster.

naw i was messing with the car before it had all this done to it its a regal we are kinda big on the g bodys

come to find out its just a 5.3 out of something he used the term "ls4" a bit loosely still bad *** for a fuel injected g body in grandma mode that will tear your world apart
