Hey. I have an easy question. I was crawling around under the Jeep a minute ago and noticed something interesting. Just below the collector flange on the exhaust was a huge dent in the downpipe. When I say huge, I mean the dent is reducing my 2 1/4" pipe down to like a 1" pipe!!! It almost looks like someone took a hammer and beat the pipe. Its close to the front driveshaft but I am pretty sure there is no way that the front driveshaft came up close enough to hit the pipe. ANy Ideas? Can I go to autozone or something and find a donut/flange that will bolt up to the header. I was thinking of just piecing an exhaust together and welding it up at work one weekend. Also, can I just take out the 02 sensor after the cat and zip tie it to the floor somewhere? Ive seen lots of civic guys do that to their #2 sensors when they dont want to run cats. Thanks

okay, here is what went down. I decided to put a straight pipe in place of the cat. Turns out the pipe coming from the collector isn't the same as the pipe at the exhaust tip. measured 2 1/4" at the back. I cannot find any pipes at Autozone or Advance that fit the stock downpipe...guess im running open exhaust until I can figure this out. Anybody know what size that downpipe is? None of the couplings I found fit it. 2 1/4" ID coupling too small. 2 1/2" ID coupling too large.

yup, just drove up to the red box with no muffler. Pissed off a guy in a z71 with flow masters because he couldn't hear his truck anymore. That was awesome.

Bought a 2 1/2" cutout, used a reducer to flow into the muffler. No cat. No problems. Everything is being welded up tonight or tomorrow. Im designing a vacuum valve for the exhaust dump. Should be easier than an electric valve to install and more reliable.

It's not our ticket, it's yours!:p I know that here in Oregon it's not a fix it ticket but rather a hefty fine. I doubt you'll ever be caught unless you live somewhere that has emission laws and vehicle inspections.

Ive never lived anywhere where you have inspections. I can burn my trash in the front yard if I wanted to.

Yeah, those HOA's are the reason why I don't like neighborhoods. I understand people want to protect their investments, but there is no investment like acreage. The benefits of owning cheaper land, and alot of it, outway the benefits of living in a HOA type neighborhood....IMHO

I'll agree that HOAs can be bad deals. Mine is pretty rational. It's a new neighborhood and everybody keeps it nice, but the HOA is hardly ever even heard from. Not one of the radical ones for sure. Just keeping dumptrucks off of peoples yards and no cars up on stands...

I've had zero problems working on my projects in the driveway. As long as they aren't there forever they are cool.

my mother has an hoa that calls the city police anytime someone parks a car on a curb. My brother got a ticket for parking on his own mother's curb. What bull crap.

That dent is there from the factory for drive shaft clearance. I wouldn't think the engine would run right without the o2 sensor taking a reading for the computer to run the right air fuel mixture.
thats a surprise? I know my shaft has slammed the downpipe a few times lol. It crinkled it up and cracked the pipe.

There is so much room in there, I wonder why they didn't just design the manifold collector to be 1 inch closer to the block, then you wouldn't have to do that dimple thing.
