This is mine. 2.5 catback with a flowmaster.10 muffler, with a dual tip.

 

It amazes me that the after market offers many cat back systems for the 4 door version of the Blazer /Jimmy but very few for the two door versions. I would think it would be relatively easy to design a cat back system for the shorter wheel base 2 door version and for the same price using the same muffler and many of the same materials. Maybe it is due to there being a lot more 4 doors out there than the 2 door models, therefore less demand.? O3jawja, your Flowmaster 10 sounds just right--not too loud and not too quiet. I would hate to take a long road trip with a really loud exhaust system.

 

Thanks jim, I was very worried about the outcome. Going from a 6.0 and 5.3 , i knew a dynomax bullet might not have been the best choice for a 4.3. I figured I would either go with a cherry bomb extreme, super 10, or a black widow race venom 250. Y pipe and cat are do for an upgrade soon!
