well i got my blitz nur spec r which is freakn big and its leaven black marks on my bumper would the kart boy longer hangers take care of this or do i just have to keep cleaning the spot? did a search all i could find about the "burn" marks was clean it. kart boy hangers or clean ???

keep the mark.............JDM BABY!!!!!!! hehehehehe

this guy told me i should get one of those panels (stainless steel) to put above it. id rather leave the burn marks then slap that APC crap on it. o well guess it will just be a weekly thing to clean

Have you checked out Varis ? They're CF and made in Japan, Fizz sells them and so is CVR Motorsports, they're priced on the high side and then there's the ebay CF exhaust finisher, the seller's from Singapore, cheaper but they're not domestic. Watch your bumper, if your tip is touching/barely touching, soon it will not be marks anymore but melting plastic.

The Kartboy hangers come in the original OEM style which is almost like stock. The long ones drop the exhaust about an inch. I'm getting the stock ones for my TBE cause the long ones make it hang low. I might go and purchase the Varis CF heat sheild depending on how things go in the future.

its not touching the bumper at all ive got just about 1/2 inch or so it looks really good where it sits id hate to drop it down lower. i might check into varis. so if i got the long hangers would it stop the marks??

The carbon-fiber bumper guard makes no sense -- CF is in a resin suspension that has to have a melting point pretty close to the actual bumper's melting point. It might look nice, but if the exhaust is hot enough to ripple your bumper it will melt the CF too.

I wish the JDM Subaru exhaust shield didn't look so odd.

its not rippling or melting my bumper its leaveing black marks from the exhaust thats all they wipe right off. all i want to know is if the kartboy long hangers will help stop this or should i find an exhaust heat shield for it?? no melting no rippling just black wipe away marks.....?

Here's your best solution:

i think subydude sells some nice looking SS bumper guards.

not a big fan of that look. alittle funky looking if you ask me. the CF one looks much cleaner and goes with the lines of the rear bumper much better. ill get the varis one after i get my DP

I had a Blitz NUR Spec and I used Kartboy's extended hangars, didn't have any issue with a burning bumper and it looked pretty good too.

not sure what im going to go with yet. i kinda like where it sits at now. might just go with the cf one

If you're trying to get it off your bumper, and it's not really melted-in, then try some Meguiar's Mild-compound clay bar, applied with a liberal amount of Meguiar's Final Inspection Spray.

You may have to first use some medium-drying solvent, like 3m light adhesive/tar remover before claying it.

I still say that if the bumper can melt, the CF guard can melt also.

I'm thinking of getting that stainless one shown below (the JDM Exhaust Finisher) and scuffing it up and painting it flat black with engine block/caliper paint. My APS 3" turboback sits about 1/4" of an inch from the bumper, it is really tight up against it. No black soot yet (I still have an up-pipe cat) but it is hot to the touch after a 30-minute drive.

in some situations, it messes with the geometry of the exhaust system...putting strain on the joints. Sometimes this stress is great enough to cause leaks. I tried them with my APS 3.5" and 1) it looked terrible...2)it was way too close to the ground...3)It put strains on the mid-pipe hanger and the axle back joint that I was not comfortable with...on the other hand, I had to use the extended Kartboy hangers with an axleback TurboXS RFL-Ti....that thing would have melted my bumper it got so hot...

I just put on the Kartboy std length hangers with my APS and everything is real tight (~1/2" clearance)...and since I am running either my stock bypass valve or an HKS 100% recirc, I don't run so rich anymore...so I get less backfires and carbon deposits on my bumper...keeps the flaming down...heh heh.
I noticed though that my APS doesn't get nearly as hot as some exhaust systems...probably due to the bigger diameter piping...

BTW...I am assuming that those that mentioned black marks on their bumpers above (not burn marks) are running 100% Atmospheric BOV's...yeah, you will get those black, carbon residues...and the occasional "Fireball" if your exhaust is a straight-through design...

ya im venting and i know it makes for a rich mixture causing the black marks and backfires etc etc. i was just curious if the hangers would aid in not leaving as much of a mark as it does. like i said before it comes right off when i wash the car with a little elbow grease. no melting ive got a little over 3/4 inch gap between bumper and tip. so not worring about melting. if i get some extra cash to toss around i might get the CF one. but for now ill just wash it
