Im pretty sure even with high flow cats, it depends on your mods and state requirements about passing smog. Only reason I dont bother with high flow cats now, is even with them on my other car, i still couldnt pass smog, it was a pretty heavily modded car tho.

Removing cats vs stock = Yes, you'll make HP/TQ (15hp range). I've seen some pretty nice dyno charts of cars with the ADM race pipe (which is made to be used on cars without headers).
High flow cats vs no cats Kooks told me I would see "a few" HP gain with the race pipe over the catted mids. So "a few" would most like be 2-3 hp or so. On a more heavily modified engine, you might see a little more than that. Last edited by SGOS252382; 08-11-2010 at 04:59 PM. |

Will your check engine light still go off with high flow cats?

I have hptuners, so I tuned the codes out. I got the JBA mid-pipes, and you are supposed to be able to put the stock 02 sensors back but because of a poor design, I coudn't put the front 02 sensor in. I had to plug it and get an extension and not use the driver side rear 02. I picked up .7 and 3mph at the track with nothing but tweaking the ECM tune a bit, !Cats and a better launch. I picked up .1 60', so that should have been good for .2 of the total ET.
