New exhaust hangers...Muffler now going to melt rear bumper???
I might need some kind of heat shield for the bottom of my bumper so my muffler doesn't melt the plastic bumper...any suggestions?
Today I installed some stiff poly-u exhaust hangers, as my 3" turbo back jiggles around too much when I go over bumps. I was able to get two of the 4 hangers swapped, and called that good, as the exhaust barely jiggles at all now. Only problem is that the exhaust tip is now 3 mm under the rear bumper...I'm not sure how hot it gets, but I'm worried about melting the plastic bumper...it used to sit almost an inch under the bumper. Do I need to be concerned about melting the bumper? Thanks.

I might be going back to stock hangers until I can find a good heat-shielding solution for that underside of the bumper... |

Leave it! Talk about JDM style. Great look. Or rivet a sheet of alum right there, that looks great too with soot ya know. No I'm not kidding.

Well You might want to take a look at Motorcycle heat shields. I never had any on my bike, but from what I could tell, all they are are like a curved piece of metal (sort of wrapped partly around the actual pipe) - with a slight air gap between the shield and the pipe (I guess the gap acts like a barrier and allows cooler air to flow under it).
You might just want to get a piece of steel tubing with a little bit larger diameter than the tip (say like 3-1/8" or so) and then cut it in half - lengthen-wise, and have someone weld it to the main tip. Make sure to have them offset it atleast 1/16 from the main tip so the air gap remains. Maybe all that sounds a little too complex, and you could maybe just buy a motorcycle heat sheild and use that instead if your really concerned about it. |

Not sure if it's still there, but I saw a bumper protector on ebay last night. Looked pretty good and it might have been an STi product....

Guys, I checked again. It's not 3 mm of space, its 1 mm, maybe 1.5 at most. Basically, the bumper and top of the exhaust are nearly kissing...
I don't want some metal shield on it. I'm thinking some kind of dark, inconspicous sheet maybe 3 x 5 inches to protect that part of the bumper. Almost like a small sheet of sandpaper, but something that resists and insulates against high temps. Even better if I can paint it red like the color of my car so its unnoticable... |

I know there is an acceptable solution somewhere out there...I might just have to get creative and solve it myself like I solved my Scooby rattles (10w7 power) this past weekend.

Does anyone in FFI care whether or not you melt your bumper with your aftermarket engine?
I think not. |

heya,
I had a similar problem and my bumper was toasted.. had it repainted once already and its all burnt up again!. Finally I got the exhaust lowered so now its about 2cm below the bumper and no burning yet. Id recommend fixing it right away or get a head sheild fabbed up. Your bumper will burn fast! |

Cool, thanks for the info. I decided to to have the exhaust hanger supports rewelded for the poly-u hangers.
In the meantime, it's back to stock...who cares if my exhaust jiggles left and right every time I go over a rough spot in the road... |

Have you already tried using zip-ties to pinch the middle of the hangers in? This will firm it up a little. Nice temporary fix...

Sorry annointed, I don't have a link to the bumper protector on ebay and I also can't find it. Good luck with whatever you end up doing!
