After search and search I've found nothing about the dynomax catback exhaust system for the 3.7L. Anyone tried this system or know anything about it? It's the cheapest I can find on summit and since I'm not really feeling like dropping a fortune on a new system, this one seems like the best choice. I'm having issues with the driveshaft U-Joint rubbing the muffler at full stuff towards the passenger side with the Frankenlift and no rear swaybar on my 02' sport so it's definitley time to replace. But I don't want to regret a purchase so before I order it I wanted to find a little more about it.

I hope it's not just another cheap system that sounds like crap. Is it smaller than stock or same size? Someone has to know something about it. Inform me PLEASE!!!

I bought the dynomax on my first car a Camaro Z28 V8 and it was the crapiest exhaust I ever heard. No performance gains and didn't make my car sound any good. I don't think it would do anything for a Liberty either. I purchased the flowmaster 40 series for my liberty and it sounds awesome. I got it from Rusty's for $250, I think the dynomax runs around the same from Summit.

If you want to save money fastrx, just get the muffler. No use in getting the rest of the pipe since you would be replacing a pipe with the same piece of pipe.

I have the flowmaster 50 series SUV model and love the sound. Not to loud, not to quiet, its perfect for my liking. Paid $100 from summit.
