no, nuthings is wrong with it. but if i can get a catco cat for like $40, i figure, why not. my cat is almost 10 years old anyway. a little birdie told me that the outlet of the hotshot header is 2.5. so, i figure i would get a 3 inch catco, and weld flanges on. at least then i have my cat for when/if i go turbo :-) Alex '93 NX2k
