Any of you guys have any experience with one...is it good or bad? Any input would be appreciated.

 

they're ok, carsound is better.

 

it sucks it cracked 2 times in a month and thats just as long as i had it

 

2 years now for me. Turbo, NOS, all motor. Been throught it all, and still works great. I'm using the 3" universal, and it's been cut and welded more times than I care to remember.

I hear some people don't like it, others love it.
