Any videos with secondary cats removed with NPP?

AbsolutHank · 05-04-2016, 10:02 PM

Just wanting a little change in volume instead of doing headers. I'd rather spend that $$$ towards a SC!

I've searched here and on YT and can't seem to find a single video clip of any member who deleted their secondary cats?

Waiting for that myself. I think Mishimoto is working on a cat back system using the factory NPP and secondary CAT delete..

No difference at idle, big difference under WOT. I tried recording a start up and rev but phone mic doesn't capture anything after 3500 rpm. I think I should record it outside and not in the garage. Only thing that you can tell in the video is the downshift is louder. You really gotta hear it in person and it is damn worth the minor cost for doing it. I also did it temporarily, waiting on catless borla xpipe. http://youtu.be/0o-w-eOTvlE

You can get your cats removed under 80 bucks, so you can still do it and not effect you getting an SC lol

These cats are after the o2's, so you shouldn't get any codes unless the exhaust welder sucks.

+1!

If the welder doesn't have an adjustable welder and is just a straight one, don't do it because they won't be able to get the top part welded thus it will have an air leak and result in a CEL. I'm above 3k miles with cats gone, no CELs.
