need new truck exhaust
The current exhaust on my 1994 GMC c1500 is leaking and i'm going to replace it. It's got the 4.3L v6, that is stock. I'm looking for something that's gonna perform good and sound better. The leak is just after the muffler so anything before that doesn't have to be replaced though I can and will if needed. But what does anyone think as far as what to get?
Thanks,
Brian

what size diameter pipe do you have for your blazer? mine has a 3" out of the cat so the muffler would be the 3" single inlet. But as far as outlet, if i go single in/dual out then in is 3 and out is 2 1/2 or i could go single in and out with a 3 in and out?

i went 3 in dual out just gott get the right elbows to work around gas tank and such and watch out for drive shaft clearance i ran them side by side then crossed over right above the pinion a little more to the back then ran it out the back
hope this helps

i actually think the 4.3 sound good with the extreme sounds like a v8 at idle and low rpms at high it gets a tad raspy but a 4.3 has the same bore and stroke as a 350 just minus the front 2 cylinders
different strokes for different folks i guess
