my cats are shot should I just run str8 pipes or replace the cats? what are the pros and cons?
catless with an H-pipe.
im catless with an x-pipe and just a tad too raspy in the low rpm's
You can.
Pros: increased exhaust flow
Cons: smell, it'll be loud as ****
I think at times the rasp at low rpms also has to do with your mufflers. My race bullets sounded very good at idle and to about 2500 rpms. Once I got into it yeah it got raspy
I am curious about what an H pipe would sound like on our truck though, got any h pipe vids?
I would stay catted in a L.
I rode in a L with an O/R H-pipe, and a Magnaflow exhaust, and that thing straight put my 03 Cobras O/R Prochamber with M55's to shame, and that's probably one of the loudest combo's you could put on a Cobra while keeping the factory manifolds. That truck was wake the dead loud even at idle, and having to yell at the person beside you while cruising at 60 MPH is not fun.
This is mine with short tubes, no cats, magnaflow.

I dont care how loud mine is. Its wake the dead loud when I romp on it...Ive made guys tearing across the highway on their harley's at 80mph break their necks and turn to see my noise maker.
at 70mph cruising and idle though its very tolerable still.
I would get the high flow cats and punch them out. I have had 2 cops look under my truck and they thought they were legit cats.
