Alright guys I am looking for the deepest sounding exhaust right now i have a flowmaster 80 is there any other muffflers with a deep sound

 

you could go with a 40 series flowmaster, but you would only have one exhaust tip, it would still sound awsome

 

I ran one on my '94 Z. Had the muffler before the axle and then Y'd my exhaust like a LM1 with straight pipe where the stock muffler would be into stock Z28 rectangle tips. It sounded great, but had a bit of interior rattle.
