upr x pipe leak

I installed my upr the other day and everything was pretty straight forward ... i used the flange provided and bought a new passenger side gasket but i have a leak on the passenger side on the back of the pipe where it bolts to tje cat back. I have loosened it and moved it and made sure it was tight and it still leaks. Any suggestions?

Thats the problem sometimes with these aftermarket mid pipes, some just dont fit right.

I'm sure you can fix it, i have no idea how tho without welding. Keep us updated, i think this is a common problem.

Re: upr x pipe leak

I got it to stop .. i used some exhaust joint sealer and rotated the flange a little and carefully tightened it back and it stopped. Idk how much the sealer helped or if it was adjusting the flange a little? And yes it is off road

Hmm, yeah sometimes those flanges are tricky. I think mines popping a slight leak it hangs lower than the stock midpipe. Everytime i go over a speed bump its scarping. Maybe i'll try the exact same thing. What kind of sealer are you using?

What brand is ur mid pipe? I have the upr and they are supposed to tuck under the car better than most others .. thats what i hear anyway. My car is lowered and i still dont scrape mine. It was something i grabed at advanced auto fpr like $7... exhaust joint sealer... dont remember the brand and im not at home right now

Oh ok. I have a dr gas o/r x. My car is really low anyway tho there is only like 5 inches from the ground to the car. The pipe tucked up really nice without the MILS, but it kept throwing the codes so i put them back in.

Call me crazy but it feels like i have more power anyway with the mils on, maybe its the angle that the exhaust flows through the pipe or something...

Thats about the clearance i have.... im lowered with the sportlines. I take it really easy over speed bumps but i did that b4 i lowered... having more power with the mils makes sense.... they tricking the computer into thinking the cats are there so ur computer is able to adjust. Thats my theory anyway..haha

Ah good point. It probably starts running in some sort of default mode which i'm assuming would be super rich.... Didn't even think about that. Good one.

Oh yeah, i lost about an inch to those things, scrape every time. Not too bad tho. As long as i dont bang it i'm good. The snail crawl accross bumps is super annoying.. I guess its a small price to pay for good looks and handling.

Im assuming u dont have a tuner since ur using mils? I just cut the rear sensors off and snipped the wires on the sensor. I left enough wire so i can splice the wires if need be later.... just saying if the scrapping gets to annoying

i actually have a tuner, use it all the time. I Haven't heard of programming your computer to the x pipe so it doesnt throw codes. Is that possible?

Hmm, interesting. I haven't seen that option on the strategy tune. I think i'll take your advice and give em a ring.

Thanks.

Damn man, if that works, pulling that damn pipe off again is going to be a b*itch! I've worked on that car a lot in the last couple weeks... glad I don't do it for a living.

Well, I could but I have to take it almost completely off to reposition it for better clearance. I think imma sit on that for a while until it really starts bothering me.

I just did a brake job on this thing and I couldnt get the damn rotors off, took me two days of beating the sh*t outta them.. i was about to take the blow torch to it until i figured out a trick. Then after all that, i put everything back together just to find out American muscle had send me the wrong size rotors haha.

I had same issue. Just turned off cats and applied tune. Usually it's dwn stream sens that need input for emmisions & fuel apps. Caused by high flow exceeding o2s cap.

Re: upr x pipe leak

Thanks for that info though! It was really helpful. I don"t know why I didn't think of that.

Re: upr x pipe leak

Hello, about the leaking exhaust:

The DIY leaking exhaust check is done at night with a flashlight!!
LOL, that's right at night with a flashlight. Here's what you do, wait till dark, crank up the motor, get your clear lens flashlight, flash it down the left and right side of the manifolds, observe for smoke. Before the exhaust reaches the cats, its smoke. Found out that my exhaust was damaged by same technique. My cats were getting banged on the street a lot becuase they were about 2-3 inches off the floor, bent them beyond repair causing exhaust leaks. That led to smoke entering the cabin via my Cobra-R hood which lets you sniff the engine while you hear it. True.

Reality Check:

If you must replace the exhaust system, minus the muffler, get a performance model, thery are usually cheaper than stock. Doing this will add an upgrade and improve performance.

let me know what you decided, and if the check worked for you. It worked for me.
