I thought about it on my first exhaust set-up, since it was so loud in the cabin, but once i switched to the magnaflow mufflers (not sure of the part number, but i'm pretty sure they were designed for the
Cobra mustang due to having the same side inlet outlet and straight through design) I'm telling you guys, my car is very livable on the highway and around town. It's almost like a slightly aggressive factory set up from caddilac or the pontiac GTO.
I'll try and find the part number for the mufflers I installed. Also, I didn't
'
t change anything else, other than the mufflers. No cat delete or resonator delete.
