I have a 95 Blazer, 4- door, 4-wheel drive with 4.3 vortec motor. nothing custom about it, just a k&n air filter. my muffler has a pretty bad leak, showed it nasty self after I had replaced my fuel press regulator and have had it run rich for awhile. Ive never put after market exhaust on my vehicle before. I have no ideal what would sound good on this truck. ill probably just change out the muffler. any help with what would sound good would be much appreciated.
