Problem with BMW Performance Exhaust -- Advice, please!

baduncadonk · 08-19-2008, 02:19 PM

I took Riss Racing catted DPs and BMW Performance Exhaust to my tuner yesterday and got a call back from him that the Performance Exhaust is not bolt on--tuner says it is not long enough and he is going to need to cut a piece from my stock exhaust and weld it to the performance exhaust.

Can someone who has the Performance Exhaust let me know whether they experienced this problem?

Also, did your Performance Exhaust come with two pieces--a shorter length of 3" tubing + resonator on longer piece of tubing?

Thanks in advance for any insights!

I do know that the stock exhaust is CUT so the resonator is removed (I think that is what it is). You cut the stock exhaust to fit the performance exhaust but there is no welding ..

Hope this helps !

Sounds like your installer cut the stock exhaust too short and is trying to piece things back together. Nate

the BMW performance exhaust is NOT a bolt on part. The midpipe section needs to be cut retaining what I believe is referred to as the secondary cats. The new exhaust can be welded or put on using a tight coupler. The coupler is the usual method to slip fit the two pieces together.

Even if he cut it too short, it's an easy fix.... if he's a competent fabricator.

The tube is kind of hard to come by though. I a few pieces of scrap stainless metric tube here (same size as the OEM BMW exhaust pipes). If you're local, swing by and I'll donate some to your cause.

The Performance system consists of two parts for the exhaust (the muffler and a Y shaped tube which eliminates the resonator), plus 2 very special clamps and comes with a new gasket for joining muffler to either the Y shaped piece or if you chose to leave the resonator in place.

There is absolutely no welding required, however if you choose to remove the resonator and utilize the Y pipe you will need to cut. What I did was held up the Y piece to the part that needs to be cut to establish how much to cut. I did this a few times to make sure. The clamps supplied with the exhaust allows you to join the new y piece to the exisiting exhaust.

Sounds like someone effed up and I'd be pissed. If you get a chance once you get the car back, would like to know your impression of the catted DP's.

Thanks,
Fran

Thanks to everyone who replied; the photos and advice made for quick solution!

In case anyone else runs into confusion with their install, my initial problem turned out to be that I didn't receive the full part set when I ordered the BMW Performance Exhaust from Leith BMW.

So, instead of joining middle pipes with the missing clamps, the tuner is welding that connection.
