I have a 97 s10 with the 4.3, i got it with an aftermarket exhaust on it and I would like to know what exhaust it has so I can get it for my blazer. There is no cat and it literally sounds like a diesel truck/semi. I crawled underneath to try and find a brand name but there wasn't. If anyone has any ideas let me know? Thanks.

 

I'm sorry but this post is about like when a gal I know and have worked on her car off and on calls me from across the state and says my car died whats wrong with it.
Get on line do some searching and compare what you have to whats available

 

^This, not nearly enough info to try to help with this. If there is no cat, then it is (at least a little) custom, as no commercial exhausts come without cats.

 

Yes it is custom, I'm just looking for guesses on the make and model of it. Sorry I can't be more descriptive. It's been on for a while as I can tell.
