So I did a full exhaust swap a couple of weeks ago. I put on an Apex'i WS2, Jackson Racing cat, and DC 4/2/1 header. Everything went off without a hitch with the exception of my exhaust hangers. The middle of the exhaust(Just after the cat), seems to be hanging a bit low. I lifted the car up and it appears that the old exhaust hangers are stretched. My friend told me I should try getting polyurethane hangers to replace them. I checked Options, il4, energysuspension, and machiii. None of them had what I need. The car has 128K miles on it and is a 1998LS. Can any of you direct me towards a company that sells urethane hangers, or do any of you have any other suggestions that could help?

why dont you just cut the hangers off the old exhaust and have them weld it to the new one?

 

no one makes urethane exhaust hangers as they aren't performance-oriented. just go to NAPA or National Auto and get new rubber hangers.

btw...are you sure you installed the b-pipe correctly? my friend's APEX'i N1 was hanging low after the cat, he took it off, turned it 180º, reinstalled, and it was normal again.

 

When I installed my Apex'i WS, due to the larger diameter than stock piping, it hit the bottom of the Skunk2 SS.

First thing I did, of course, since I was still under the car, was bend the metal hanger posts on the exhaust. That fixed the problem.

Of course, I bent the posts up, so that the exhaust would hang lower. You could try to do the opposite: Bend the posts down, so the exhaust doesn't hang so low.

OK, then I got my high-flow cat, which ended up moving the whole exhaust towards the back of the car by a fraction of an inch. So now the exhaust was rattling on the heat shield on the gas tank.

So I roughly measured the existing rubber hangers, went to Pep Boys, and bought longer rubber hangers. Pep Boys had about 4 or 5 different sizes. I think I ended up getting the hanger for a Ford pickup. That big hanger had several different holes/openings. If I had used the furthest-apart holes, the exhaust would have been hanging very low. I ended up using one hole and one opening. Since the opening is way larger than a hole, I used part of the old rubber hanger to fill the void of the opening, so that the rubber hanger wouldn't fall off.

As for rubber vs. polyurethane.... dunno. It was hard, black and rubbery. Could have been polyurethane. People say to upgrade to polyurethane bushings for motor mounts, shifter bushings.... but I've never heard of upgrading to polyurethane for the exhaust hangers.

Sorry to ramble....

 

I'm fairly sure we installed the B pipe correctly. The hangers look like they would only go on if we placed it the way we did. I'll look into new rubber hangers though. Thanks for the replies guy's. Fortunately my cat didn't appear to move my exhaust back any further than the stock one. I'll also see about maybe bending the hangers on the exhaust so that it doesn't hang as low. It only scrapes on really bad speed bumps. I still don't like that though.

I just installed a cat-back system on my '02 Accord (4cyl coupe), and it hangs about an inch - 1 1/2 inches too low, especially at the rear (from the rear axle back), plus the muffler hit the (OEM) rear valance until I bent the hangers on the muffler. I am using the orig. (50k miles) rubber 'doughnuts' and the new cat-back's heavier weight than the original seems to have strectched the original Honda rubber 'doughnuts'.

Question: are any Honda or Acura 'doughnuts' any shorter (distance between the hole for the body mounted hanger rod and the exhaust or muffler mounted hanger rods)? I seem to recall that 2nd gen Integra hangers are shorter than the 6th gen Accords. Or, is there a good source online for univeral rubber hangers that are of the same basic configurtation as those used by Honda? Thus far, Googling hasn't turned up much of anything.

I'm trying to avoid heating the s.s. exhaust piping or bending the mounting rods too much for that throws off the geometry of how the entire system hangs - okay now as they match up almost perfectly with the stock location -just way too low. . .

re: urethane or poly-urethane hangers ('doughnuts') - I saw a listing for them on eBay, but I'm concerned that they may be too stiff, and could cause either vibrations, or even cracking of the header, etc.

Thanks
