which is better sounding in duals? pypes x pipe and street pros OR flowmaster AT's or 40's and H pipe?

ive heard both now in person and i can definietly say that the flowmasters with an h pipe sounds better if you want deep and loud. just depends what you want. they both sound good im not putting either one down.

ok...so american thunders or 40s? ive heard theyre pretty much the same but ats arent quit as loud but someone whose heard both?

i believe therepretty much the same just the at's come with 4' tips. i got my dual ats off ebay for a a really good price.

the ats are already made to fit the car...the 40s is the type of muffler they make and will need to have tips/pipes/hangers welded to it
