So i finally figured out how to stop exhaust from hitting my bumper, and thought some of u guys may want to try the same thing.
I'm drilling at least two holes in the lip of the cut out where the exhaust tip hangs out. I put yellow dots on this xB bumper so the get the idea for the placement.

In each of the holes I'm putting in a SMALL rivet with a round head like so.

The rivets will give just enough space to keep the exhaust off the bumper as it swings over. I'm getting black ones so you wont even notice they r there.

What do u think???

I'd be concerned with the rivet scratching up the exhaust. Probably not as noticeable as a melted bumper. If there's not enough clearance, the exhaust might touch the rivet all the time and heat up enough to melt the bumper? Probably not though...

 

i have an after market exhaust and i have no problems with it melting the lip.i also commute 130 miles a day so if you have that problem with a stock exhaust take it to the dealer and have them fix it.

 

Yeah, if your stock exhaust is melting your stock lip then you have an issue. Hit up the dealer....

 

Um, just make sure the rivet is high temp plastic or something like that. If it's metal it will simply conduct the heat from the exhaust and melt the area immediately around the rivet.

Just my thought on the situation.

Yep- there's some problem with your exhaust that the dealer can fix... my oversize TRD axleback (90mm tip) hangs dead center, as did the oem unit...

 

if the rivets are metal, I'd wager they'd make an annoying rattle.

 

grizzly_choppers and PunkInDrublic bring up two really good points. If you can get some high-temp non-conductive stuff, you're good. Nylon? Kevlar? I dunno. But yeah - if it's stock, the dealer should fix it.

Had the exact same problem with my TRD axle-back. Wouldn't stay centered in the cutout opening, even after I "horsed" it over with a rubber mallet (mine kept wanting to slide left, over toward the center of the car).

Go to an Ace or other similar hardware store, back where they have all the plastic flip-top boxes of specialty stuff. Look for a metal washer that has a hole same size as---or slightly larger than---the muffler's metal hanger. Then look for a white NYLON bushing (same size inner diameter as the hanger's outer diameter, and maybe 1/4" wide).

After pushing the muffler over where you want it, brace it so it can't move. Slide one of the metal washers onto the metal hanger SNUGLY up against the rubber hanger, followed by a nylon bushing (use a flat-blade screwdriver to slowly ease it on, since it should be a tight fit). I went overkill and added another metal washer followed by another nylon bushing. Year-and-a-half and 35,000 miles later, still right there in the middle of the cutout. Good luck with yours . . .

 

JUST TO RESTATE: thats not my car in the pic, My exhuast is a strup, the rivets wont rattle if done right, and like somebody said earlier if the exhaust is touching the rivet long eneough to heat it up you have bigger problems. this is a precautionary thing that def wont work if the tip is always sitting against the rivet

 

i have the strup also.the guy i bought it from said that his lip was melting too.i found that if you play with it alitle you can get it to fit dead center.just move around the rubber hanger ultill you get it were you want it.i havent had problems with it yet.

 

The correct answer is, you leave it alone because burning your lip is what cool people do.

You can kind of see mine burnt up in this pic :)

 

the gasket at the begining of the exhaust may need to be reposistioned. i did thins and have had no problem. even a 10 hour drive averaging 75 did no damage to the bumper. also zipties will work too. their is a thread in drivetrain and power you can look at.

 

that's cool, rAndal.

 

Before you do all that clandestine stuff.

Get a new gasket and clamp and bolt for the rear assembly.

I just called dealer in NJ.

Bolt for clamp is around 2 bucks.

Clamp is under 15 bucks.

Gasket is under 20 bucks.

I have to go up and pay ahead of time and wait for them.

I can't find them on-line.

 

I just put my strup on and used a new gasket clamp and bolt. Position it where ya want it. I pushed the mounts fully into the rubber hangers. Then tighten the clamp. It should stay spaced evenly with about a 1/2" clearance all the way around. Also love the sound of the Strup!!!!

 

+1 for theShortBus - washers and nylon bushings. the can moves because it can. you stop it from moving, you solve the problem.

it's pretty much what I did too.

 

WHenever I've seen the problem of the exhaust tip wandering, it was fixed by replacing the little donut gasket that goes in between the axle-back and the rest of the exhaust system

 

Exactly right!
