So I have noticed a significant decrease in my low end performance. got under the car and felt for some exhaust leaks and noticed that my buschur downpipe is leaking around the rear part of the flexpipe.

I have emailed buschur about this and am awaiting a response.

I recally someone else having this issue prior but dont recall whom. a search yeilded no results. anyone else have this problem?

does anyone know how difficult this will be to fix? I can welt .. i was thinking about unwelding the pipe from the flex area to examine, but im not sure what im getting into there ..

thoughts? thanks!

 

That's one of the downside of an exhaust system that comes with flex pipe.

 

I had the same problem with my RPW downpipe. I took it to a muffler shop and had them cut the downpipe and reweld it, creating a much better seal. You may also want to check if your gasket is blown, cuz I know mine would blow all the time. Best bet is to get a 2.5" gasket from the stealership - ask for the evo exhaust gaskets.

 

Same exact spot that mine started leaking. If you do unweld it, you'll find that the inner piping of the flex portion has blown out. Buschur is going to tell you that it's $100 plus shipping to fix it.

I took it to a local shop and paid him $80 - $60 for the flex pipe and $20 for the labor of welding it (because I didn't want to weld it).

 

Buschur quality = S H | T

 

Alex = harsh, but at times, I've thought so.

My experience:

Downpipe - leaked after 1 year of ownership. Yes, I live in Ohio, but Buschur does too, so it should be safe for salt, etc.

SRI - horribly designed. Seated directly behind the battery, you can actually feel it choking from lack of air flow. Doesn't exactly fit the MAS and required brute force to install. And it hits the fuse box because the intake pipe is poorly designed.

High flow cat - welded on backwards. If I hook it up correctly, the air flow is going into the "out" end and out the "in" end.

Gaskets - like any good company, they include gaskets with exhaust products. These gaskets do not actually fit their products. The holes do not line up at all.

 

thanks for the info guys. im gonna re-install my stock DP and will unweld the buschur one I think to investigate and see whats up and if i can fix it.

im still hoping to hear back from dave @ buschur tomorrow .. they've been pretty good in the past and i would hope to not expect less.

i love my buschur exhaust ... i loved the DP until it started to leak.

we'll see. thanks again!

 

uh... all my buschur parts work fine... i didn't get the down pipe tho... as for the sri design... would there have been another possible route?? no....

 

Digdat - good luck. Dave was always 50/50 in answering me.

KU - yes, your parts work so far. But I could be wrong.
And yes, the SRI can only go there, but if the intake pipe was bent a bit more, it would simply inhabit the empty area that the stock air box used to fill. But instead, it's run so it's touching the fuse box. If it was bent more, there would be more fresh air hitting the filter as well.

And I honestly do suggest you purchase the DP. For those of us who can't afford RPW's header/DP system, this is the next best thing. The Buschur DP was my first powertrain mod, and I can honestly say that even with everything else bone stock, I felt a definite difference. For the time that my DP was in one piece, it was an excellent mod. And I'm looking forward to putting it back on now that I've had it repaired.

 

RMR found another possible route.

 

Flex pipes are known to leak. I can't say I've ever had a quality issue with a Buschur product. Alex_alex, do you have anything to back that comment up?

 

yep. The search button. At least for evo parts anyways.

 

Whats the downside to not having the flex pipe?

I read it stresses the o2 housing?

 

Doubtful. But it'll put more stress on the downpipe itself (because there's nothing to flex/bend when the engine shifts).

 

If you look at the buschur downpipe the most extreme bend(other than the 90) is on the backside of the flex. Not hard to believe this would be a problem area. With a little knowledge of metal working, it should be a minor fix. After I put mine on I noticed the lowest part of the car is the flex pipe! I'm sure bottom-out would also change the quality of the dp!
