Texas Speed makes a 3 in cat-back exhaust system for 98-02 f-bodys that is gaining popularity.It is called the "Texas Rumbler". I wonder have any of you guys tried it on a 3rd gen yet ive heard the exhaust systems are very similar and wondered would it work on our cars. It sounds great on 4th gens and its a free-flow muffler not restricted as much as say a chambered muffler.

It will fit like any other 4th gen catback. Minor modifications are needed, mainly connecting the I pipe to the cat connection. It's essentially a non stainless SLP loudmouth that utilizes a dynomax bullet instead of a SLP resonator.
Hope this helps
