In the process of turning my 2002 4door into an overlander. Next to replace is the muffler and exhaust. Doesn't seem like it it's worth trying to get power out of that upgrade (but I could be convinced). Thinking I should focus on weight and noise instead.

Any model recommendations?

BTW, I know next to nothing about cars. This is my first upgrade project. Thanks!

2002, four door, what?  Presumably it's a Suzuki of some sort, or maybe a Chevrolet Tracker, but a little more detail would be nice, and whilst you're about it, what engine does it have?

Details, eh Sorry! Late night post.

It's a 2002 Chevy Tracker 2.0L with 4wd low.

Guess they're not all identical!
