I have an El Camino with headers and a high performance 454. I had 3" exhaust with Flowmaster 40's put on and it was brutally loud and obnoxious with full tailpipes. I then installed 12" glass packs in the tailpipes just before the exit to act like resonators and it mellowed the sound down, but still sounds good. I just put Magnaflows on my 67 Olds 442 and they sound great.
