Cat removal with stock exhaust?

tower74 · 02-08-2013, 09:28 AM

Well to remove the stock cats..one it's a federal offense...just saying on that one but I doubt they will come after anyone for that one. Also it will throw engine codes for both banks unless you get them tuned out. I know, I more or less had straight pipes on my old Z. Driving it was a beating due to the noise but the turbo made up for it. You will have power gains somewhere around 30+hp gains.

With the F.I TP's you will NOT through a code due to the extended 02 bungs.

I had the Berk test pipes on mine and it threw the same codes all the time. Just went into Cipher and shut them off.

It's illegal to remove a working cat. Poke a few holes in the OEM cats after you get them off and claim you hit some road debris.

Well that's the Berk, if I'm not mistaken those are more likely to throw codes, especially since they don't have the extended o2 bungs.

Lol, I'm really not worried of authorities raiding the shop while my cars getting the pipes installed just to make sure they aren't removing a working cat.

I've never heard of anyone having an issue with the feds about removing a cat. Technically, though, it is illegal. If they ever decide to enforce it 99.995% of this forum is getting popped, myself included.

I burnt mine up...so spending $1300 on a new set or $200 for some test pipes. Easy choice...plus the hp gain

Hell no...I paid $150 and he was surprised I was willing to pay that much. Dealer wouldn't take it back with test pipes
