Montreal STI please post pictures of the damage. Do you have the stock muffler and tip? Is it touching the bumper?

FWIW

Any time you do a hard track day most aftermarket exhausts melt the bumper. I have prodrive muffler and it melts the bumper. HKS is another.

Get some exhaust wrap and use some hose clamps for the track. Takes a couple of minutes to wrap the tail pipe and a minute to take off at the end of the day.

From a track day last year, read the end of the first post and a few more.

You could do just what you decribed above with some sheet metal and tin snips, a dremel to soften the edges, then, do it again, and samitch some header wrap between the two pieces just to make sure the heat wont transfer.
You should be able to find everything at the hardware store for under 10$ if you have or can find a scrap of header wrap and have tinsnips and a dremel...
Even buying the tools youd still save over the worldown3sperformance piece...
Good Luck!

I don't know how so many people can put up with melted bumpers like it's no big deal. It is something that shouldn't be happening. It's not hard to make it so the tailpipe is 2-3" below the bumper and about an inch sticking straight out beyond the bumper. You can run the STi HARD all day long till the gas tank is empty on the stock muffler and your bumper won't melt. I cannot see the justification for paying $1000 + for an exhaust system only to have it melt my bumper. I can assure you I won't be buying one that does this. Goes to show that certain companies out there do not do much R & D on some products.

Honestly, for the TXS RFL-Ti guys, I think all TXS needs to do is have the muffler stick out about an inch or so more. It sits a little deep that's why all the soot builds up on the bumper, I dont think height of a muffler really matters(unless its 1mm away from kissing it) as much as how hard its driven. Otherwise, a lot of aftermarket mufflers are bound melt the bumper after a few hard track sessions. It's not like a somewhat melted bumper would be totally unexpected given that the car was running WOT or close to WOT over a certain duration of time.

My bumper is f-in horrible after the TXS RFL turbo back. I've put 1500 miles on it since the install and the bumper looks like golden fried poop, it bothers the hell out of me and I can't ration putting that hideous metal plate on the bumper. I may have my buddy weld in a piece of pipe to have the muffler stick out a little more, and different hangers to let it hang an inch or so lower. Its an eyesore, worst I've seen yet. I may have a pic for you guys to see later tonight. Running catless (as I am) worsens the problem.

Also, since the RFL comes out at a slight angle, that plate would do very little to stop bumper damage. My bumper has browning at an angle, away from where the plate would cover. I wash it off as much as i can every time I finish driving, which is a hassle, but bumper is perm. browned. Needs a repainting or something halfway attractive to cover it.

It would be nice if someone knew how to make a carbon fiber piece to place on the bumper that is wider than that metal plate thing (which is an absolute rip off, btw). Carbon fiber has very good heat dissipating properties, so that would be ideal and pretty cool looking. Any ideas, or anyone know how to mess with a piece of CF? I may look into having this custom done.

^^ post pictures of this bumper browning. And I can't for the life of me understand why so many people are using TurboXS products because they seem like nothing but constant problems!

If someone wants to host the pictures, I can show you the pics of my melted bumper.

Remember I have a white STi so it looks even worse. TurboXS says it's an install issue but I don't seem to be the only one with this problem.

I agree. Maybe this is common to STi or WRX, but it certainly does not apply to all cars. I hang out on the M3, M5, and C5 forums for years now, where there are dozens of aftermarket exhausts that see track use, and I've never, ever heard this complaint.

I agree with the other posts, extending the exhaust tip an inch might help, as well as keeping the distance from the fender to at least 1/2 inch. Also if they made the exaust and tip separate parts, with insulation between them or just a crimp or rivet holding them so that the heat conducted isn't as much.

That this is somehow acceptable for a "performance part" is really just an excuse for not designing the tip right the first time and trying to cash in regardless of the mistakes made rather than trying to correct them.

Pics should be up soon, another user has offered to host them.

I am putting on the high-flow cat so I am thinking that the exhaust will run a little cooler now, we'll see.

Also the idea of putting on a plate suck so I have to go to a muffler shop to see what they can do. So far I am not impressed with TurboXS who seems to have been doing this for a long time.

I am still investigating if it is an 'install issue' however the mechanic who installed it said there was no room for maneuver and that the exhaust was a perfectly tight fit. He wondered how such a nice looking exhaust would not clear the bumper and be so close to the plastic.

Anyhow I will update you as this develops,

Rob

I have posted Rob's burnt bumper pictures at:

Look under "Rob's Burnt Bumper" directory and you will find the five JPG photos that Rob sent me for posting.

Mine looks just like yours does. I don't think there is anything wrong with the install. My bumper has just stated to show signs of the melt. No where near as bad as yours though. I am running the high flow cat though. I am going to the hardware store today to try to come up with something.

Have most of you had this happen after track use or mainly daily driving? My RFL ti axleback should be here next week. I'm worried about it now because I don't want a melted bumper. That'll bug the hell out of me since I'm a neat freak about my car.

How about a list of some exhausts that are confirmed to fit the sti correctly without melting the bumper?

I am buying the APR CF radiator plate from Digital Racer and showed him this thread. I let him know that there would be a decent amount of interest in a CF piece for the bumper. He said he would look into it.

I am looking into making one myself. I have been a high-end custom car audio installer for ten years now. I have done a lot of fiberglassing, mold making, gel coating etc. CF is not much different to work with. I just think it would be easier to buy a $50 -$75 piece from someone else rather than make it myself. We'll see what I come up with!

Call me an idiot...but what's the difference between stealthback and turboback and which would be better for the STi?

The stealthback only includes downpipe, racepipe or highflow cat, and a mid pipe. It bolts up to the stock muffler. The full turbo back includes an axleback muffler as well. You'd get the most gains with a full turboback, but I've heard you only pick up 5 horse or so with an aftermarket axleback on top of the stealthback. (If I had an Sti I'd keep the stock Sti muffler and get a stealthback)

A stealthback could be had with a high-flow cat pipe rather than a racepipe as well if I understand correctly.

But then, how do you justify replacing a working cat even in the case of the HF catpipe configuration? Apparently, even a catpipe replacement is not legal in many states & provinces?

OK so my home made Exhaust shield is in place. Looks pretty getto but it does seem to work. Got a sheet of galv steel from the local HD and cut out a nice rectangle. Folder it in half and put sticky Insulation on the top side. Formed it to the proper curve to fit along the bottom of the bumper. It sticks out about an 1/8th inch to the pass side and maybe a 1/4 on the drivers side since that is where the exhaust seems to be directed. Screwed this make shift piece into the underside of the bumper.
Slight Exhaust harmonic at about 82-84 but as long as you go faster it's fine. I can try bending it different to see if I can get it to go away. True test will be on Oct 6th when I go back to the track.
I'll try to take pics in the next coupoe days if people are interested.

Seems to be an inherent problem with the new Sti. Here is a quote from the new modified magazine:
"Another obvious trait of the Sti is that it runs hotter than a hooker on payday"
"The engine is hot and the exhaust is even hotter, so don't plan on transporting any ice cream cakes in the trunk. It's like an oven. We contacted Fluidyne in Ontario, Ca. about the inevitable heat problem.........

Umm..yes I did. Go re-read the post. (I was the third person to post)
Your right..I've been busy posting I'll make sure I correct any post I made and insert the word "aftermarket" I'm just doing the same when anyone else hears about problems. I'm discussing the issue..is that ok? No different than someone on this board discussing issues with the Evo or any other car for that matter. I quoted a magazine article that I'm sure most people haven't read yet. Settle down..I'm not trying to bash the STi

The posts have been corrected. I added the fact that it is with aftermarket exhausts. You may want to review them to see if they are satisfactory.

I know you read the EVO-STI post...I said you didn't CROSS post that one to EVOm. But you did manage to cross post 2x the post about aftermarket exhaust problems.

Discussing the issues is fine (IMO) I just think grabbing one piece of bad news and running back to EVOm to gleefully report it is childish.

And I never accused you of bashing.....although I guess that's what you're doing

pk!

edit: correcting you posts is honest 'cause it's not really "another STi problem"
