Hey everyone!
I recently got an '05 Alabaster Limited crossfire with cedar and black interior.
The issue is that, being 7 years old, i think the cat may be degrading and blowing into the muffler, so there is an incredible rattle around 1400-1600 and 2300 rpm. Its starting to annoy me. I want to do an entire new exhaust. I was thinking of welding 4 universal cats, and then a megan m-rs muffler (link below) all together. I was wondering if anyone has done this or something similar. Hints and tips are always appreciated!

Thanks guys!

This is my custom set up:

The front cats are going to be really tight. I just replaced my rears with two small high flow bullet cats after both cats rattled...if you wait about 2000 miles the cores should turn to dust and blow out, but I will tell you the car was much louder and suffered a slight hiccup in power with them missing the cores. You can check eastern catalytic and they make a complete exhaust system with both fronts and rears and all pipes and you should be able to snag it for around 600.00, for us SRT6 owners it appears its off to mercedes for rebuilt systems at 2500.00.

 

Thanks guys, although upon closer inspection i think the cats have been replaced and its just residual stuff in the muffler, which is much cheaper than the entire system, so yay for that
