    I know alot of people have Flowmasters and love them but does anyone have any input on Borla Mufflers. Lookin for the usual sound, very deep, throaty, defined, yet not super load. I'm not much for glass packs so I figure I'll give mufflers a shot.

    I've got a pair of Borla Hemi Mufflers on my K5. They aren't too loud at part throttle, but they really wake the neighbors up when I stand on it. [​IMG] Perhaps on a newer truck with cats they wouldn't be quite as obnoxious. [​IMG] You can see through their Hemi muffler, so I guess you can't expect it to be too quiet. Mine cost $104 each back in 1987 or 88. Don't know what they cost these days. The cool thing is that they still look as good as the day I bought them. Those things will last forever! [​IMG]

    Thats amazing that they last that long! I don't have the cats but I'm sure they'd have something tuned for what I'd like. I'm gonna be interested to try them. No one ever seems to talk about them, I've only heard about the Flowmasters.

    I've got dual 3" 2 chamber Flowmasters on my big block Chevelle and there as loud as I could have wished for. I'm talking my wife can here me comming home from almost a mile away. On my Blazer I have a single 2.5" 3 chamber and it's loud enough to make your ears ring after an hour long ride. Let us know what you choose and it works out.

    The Borlas are made out of 304 stainless steel. They'll still be looking good the day they haul your truck off to the junkyard. [​IMG] Most muffler shops can build you a set of pipes out of 409 stainless. It's not quite as good as 304 but it can be bent in a regular exhaust pipe bender. With that pipe and a set of Borlas it will be a really long time before you're visiting the muffler shop again. [​IMG]

    I haven't noticed it. But I still have carpet on the floors. [​IMG]
