I was looking at modernperformance.com and was looking at perhaps purchashing the MPX dual exhaust and there's an option for Catalytic Convert or Cat Delete. Can someone explain to me the difference, the benefits of both as well as the downsides of both?


Thanks a bunch!

Converter:
Bumper wont be black
Deaper sound
Almost no restriction
Not commiting a federial crime

Test pipe:
Louder
A few hp
Blow flames more often

Do you have an SRT-4, or swapped, or using an SRT turbo? If not, I wouldn't get this part. The MPX exhaust kits are made for SRT-4's.

don't get the cat-less one if you're not turbo. I drove around with lth straight to muffler, and got pulled over at least 4 times in a 6 month period. It will be loud as hell

As long as you run a solid muffler system, the cat option wont make a huge difference in sound. Straight pipe w/o the cat is going to be super noisy though. BYR said it best.

The cat delete is just cheaper version of a true high flow cat. Get a magnaflow/car sound high flow cat, it's as straight though as you can get while still being legal. I got one for my old car, and if you hold it up to the light you can actually see through it, not clearly but you can see light through it.

I hate to be a stickler, but there is a very good reason for cat. converters. I would bet money the magnaflow cat flows just as well as a test pipe without the ozone destroying emissions.

I'm in active talks to buy a srt swapped neon so I'm looking at exhausts.
