Performance exhaust for a 89?

Anybody know if a company sells any performance exhaust options for a 89? I'd hate to go to the local shop and get a regular exhaust. :-)

if you can stand the noise, I would suggest just cutting it off and straightpiping it. Or, some guys like to put stacks on their rigs, that's cool too.

The only thing removing the stock muffler does is raise the noise level. It does nothing for performance.

A 4" system is a good improvement.

Where ever you look at exhaust make sure it comes with a 4" down pipe. A lot of places list a 4" system. But they only have a 3" or 3.5" down pipe in the kit.

Stans exhaust is one place.

Source automotive is another.

I say straight pipe it and add a BHAF...That will get you a little bit of a gain... Easier breathing the better it performs...
