I had sound in the vid...
I was always a fan of Magnaflow. I ran it on my 99 Tahoe after I threw out the Flo Pro. I ran it on my Crown Vic initially but those modular Ford motors have some drone to them stock and the mufflers only made it worse...I ran them for a couple years and ended up putting on a set of resonators...Those helped out alot but I think I'm getting old and dont like much sound anymore so thats running stock now...
I did run Magnaflows on my 94 LT1 Caprice and that sumbitch sounded ferocious. It was deep, throaty, and very mellow and just sounded wicked and didnt have that typical Flowmaster crackle...
I also bought a Magnaflow 4" for my 04.5 LLY when I bought it new. Nice sounding system but the drone started to get on my nerves after a few years so I switched to MBRP.
On a gas engine, I'd definitely recommend a Magnaflow. Deep and throaty and not really loud at all. Very unique sounding exhaust.
