I Have an 86 F150 302 and I put on Flow tech Red Hot Glass packs. When we fired it up it was quieter than the stock mufler. Than i herd later that the length of the glass packs affect the sound. I have 27" packs and a Catalytic converter, wold this be why i don't hear the rumble? Would an 18" or 12" sound better? I also herd that their is a break in period for the fiber glass to break up, how long befor i would hear anything or would i?
I am primarily posting to this thread so i can be notified by e-mail when someone who knows what they are talking about posts a reply. I am about to fire up my 1978 F-150 (351M) with full straight exhaust and coincidentally 27" Cherry Bombs exiting before the rear wheel wells. Don't know if it's legal, but they'll tell me at NJ inspection.
If you are looking for good performance and a real nice sound that doesn't sound like you are pulling off a race track, I reccomend 40 series Flowmasters and a high flow cat. I've used such systems on many fox body mustangs. They are plenty loud and truly compliment the 302 sound.
