I bought a UR test pipe from a board member and checked it for fitment this evening. I was dissappointed to discover that I should have done my homework first. The exhaust the previous owner of my Evo put on was an RMR downpipe and AMS catback connected with a shop-made Vibrant catalytic converter.

Is there a test pipe made to connect these exhaust pieces? Should I have a custom pipe made, or replace the catback so that I can use the UR test pipe I just bought?

Please check out the pics.

 

that testpipe is a stock cat replacement...

you will have to get custom piping done... sorry

 

Just send me the converter assembly and I'll make you a test pipe that won't throw a CEL!!
PM me for cost

 

Do what I did
Take a look at my "test pipe" It is just plain aluminized 3" piping I bought for $15. Paid a guy $15 to cut my flanges off and weld this thing on. Looks ok and works... if you want it to look perfect buy polished stainless and weld that on. Here are the pics:

How about this: where can I can a set of flanges, one 3-bolt flange and one 2-bolt flange for welding up a custom test pipe?

Thanks.

 

Make them. Flat stock, a hole saw, and a drill, + patience

 

I would rather buy them. Perhaps I will call AMS as I am confused how their catback could have ever bolted up to the stock cat.

Thanks.
