Just had the catylic converter removed today. The car sounds more aggressive. Gonna see if it actually is at the track tomorrow. Was hoping to have the 3:42's installed but didn't have time. Also gonna install the 160* stat and HPP III at the track to see what kind of direct results we get from that. Should be interesting.

 

i was pleased when i removed mine.

 

I had the opportunity to hear my hooker cat back with the cat and without. We left the cat on because we didn't have the time to swap in the ORP, the hooker with cat has a nice deep tone, sounds mean as hell. I loved it, we took the cat off, got louder, still deep tone, and has a cackle/growl that I wouldn't trade for the world. Catalytic converters SUCK!.

to the !CAT mod.

 

yeah, when i took mine off, i was totally stoked. it sounds great. i dont know about performance. i guess maybe a little bit. i cant wait to do longtubes. i think ill get a little bit more power that way.
