I bought a turbo-back exhaust about 8 months ago from Buschur. DP, test pipe, and cat-back, all slip fit. I had big problems with the DP fitment. They sent me a new DP, no questions asked.

My problem is the connection between the DP and the test pipe. Every clamp they send in their kit is tapered. On the slip-fit sections, one side is bigger than the other, so one pipe will slide in the other, and you put a tapered clamp on it. Obviously the big side of the tapered clamp goes on the bigger pipe.

My DP/test pipe connection has no taper. The pipe on both sides of the joint are the exact same size. The DP expands at the end, and the test pipe is reduced on each end. I 'm not saying that it necks down and restricts power. I am saying that the clamps they supply don't work for this joint, since one side of the clamp is bigger than the other. Both of the DPs that I had from them produced the same results.

I direct you to my expert Microsoft Paint rendition below for a pictured analysis. See the "circled" area:



I talked to them through PM when I got the exhaust. No solution except to have it welded. I called them recently, and they don't have any non-tapered clamps. I have tried to find some locally, with no results, and they don't know where to get any. I'd rather have a clamp than have it welded, in case I ever sell the exhaust. Can someone point me to a 3" non-tapered exhaust clamp? Anyone else with this problem?

 

The picture that you posted, is that the way the exhaust you have from us is? IF so that is the way it is suppose to be. One slides into the other. Then the large end of the clamp goes over the pipe that is on the left in the picture and the small end to the right. In reality the offroad pipe or highflow cat is the part that is larger and the downpipe slides into one of those two parts.

Let me know what to do to get this fixed for you. Can you send me a picture of the parts on the car?

Thanks,

Yes, that is exactly how it was when i received it. One side is not larger than the other, at the joint. Both pipes on either side of the joint are exactly the same size. Exactly. One side is not bigger. This is how all the other joints are on my exhaust:



Notice how in the circled area, one side is bigger. Because of this, the clamps fit perfectly. In my first pic above, both sides are the same size. How can a tapered clamp fit the joint in the first pic? The space in the first pic is the joint, the part that needs to be sealed. But using a tapered clamp, one side clamps down on the pipe great, while the other side doesn't even touch the pipe. I have an exhaust leak here at the DP/test pipe joint because of the clamp.

I will take pics tomorrow and post them.

 

In the first picture you show the pipe slid together, do they slide into each other on your car?

You can just give us a call and talk with me if you want.

Yes, they slide into each other, as shown in the pic. I sent you a PM with links to the pics I took of the connection. Let me know what you think.

 

I see now what you have. You are correct in the drawings, description and in the fact the clamp we sent will not work. Crap.

I don't remember why we did the downpipe like that but that was an additional extension we put on some of them for one reason or another. A band clamp is not going to work.

A standard exhaust clamp will be the best bet to seal this up. I'd be more than glad to send you one for free.

I ran this by my dad too, we figured it out. We can actually get those band clamps without the step in them, so they would work out really well.

Just give us a all at the shop and we will send one out, I'll have to order it and will have it next week.

Sent another PM. Thanks for taking care of this.

 

Sent you an e-mail with the requested info. Thanks.
