Question Rear Bumper

Well...
Many of you know the problem I had when I took my car out to the track. The conditions were extremely hot and the exhaust tips were even hotter, thus melting the rear valence around the tips. You cant really tell, but it is there. If you look closely you can see it.
My question is....can this hole in the valence be repeaired economically?
Or should I just get a new rear bumper? (A different aftermarket one)
I just wanted to hear what some members had to say. I am leaning towards getting it repaired becuase I dont know if I can just get an aftermarket rear valance and not get the side skirts and front part. It might not look so hot.
Any opinions welcome.
Thanks
MIKE

Wow, this is the first time I've heard of this happening. Is one of your mods an exhaust? Maybe you could either change the hangers, or have an exhaust shop change the angle of the tips to move the tips further from the valance. Since the exhaust openings aren't "right there in your face" visible, you could probably get it fixed and they might only have to repaint the recessed area at the bottom of the bumper. These are just guesses without seeing the damage. Maybe you could post some pix.

Mumbles....Borlas are on there right now.
Really cant change the angle....They fill out the opening nicely....too nicely. I will try and post some pics this week. I have to get them scanned.
Thanks for the advice.

Yes thats happen to a couple of Borla owners. Most of them just use some kind of heat insulation between the bumper and tip! Ask Lexciting!!!!!

Wouldn't a piece of metal just conduct the heat to the bumper anyway?
I dont understand....could you post a picture?

What sort of heat resistant materials are out there that would work and look good?? Lexciting anything?

Alexus....It is safe to put the tips on your car....I was out on a 100 degree day running the car hard on the track. I dont think I will run into too many more days like that. The borlas shifted a lot do to body flex and eventually touched and melted my valence.

Thanks

that is an odd suggestion at first, but you could tweak it to work. first off, the metal piece could cover the entire inside or sides of the valance opening, so it would distribute the heat over a large area. or the metal piece could cover that and extend as far back as you like to really move the heat around.

a picture would be worth a 1000 words here. heck, it might even look good!

Looks like the exhaust physically moved and touched that one side.

I'd call Borla and give them hell.

Good luck.

Default It did move....

The exhaust did move...
The exhaust has some bar stock which has a rubber end that is connected to a hanger on the frame. All cars have this type of setup as far as I am aware. The exhaust has to have some give to it to allow for flex in the system. This will prevent any metal from stressing or cracking.

Yup, I got the same exact thing happen to me. I ended up buying another bumper anyway, but this time I will make a bracket for the muffler so it won't move, and maybe get some black heat resistant tape to protect the bumper.
