I'm looking to put a single cat-back exhaust on my 98 LS 4WD/4-Door.
Anybody mind pointing me to a few web sites....

Appreciation in advance.

Depending on your model...you might have to gent one custom bent for you. They don't make many exhaust systems for the blazers.

 

your other option is to just replace the muffler if your just going for sound.

 

I'm going for better performance and less rot

 

If you're going with the performance theme then I say go for the full exhaust system (headers, downpipe, etc.), bore out your TB, throw on a CAI, mass airflow sensor, and if you want to, a new intake manifold. That should start you off pretty good with your intake/exhaust setup.
