Well my shiny new Cattman y-pipe came today and I already had my car up on jackstands. After a couple hours I had the stock y-pipe off with only a few hitches. Anyway I got ready to put the Cattman on and I just can't make it fit. It seems like the distance between the two pieces that make the "Y" is about 1/2" too short. I've been trying for several hours to make it work with no luck.

Anyone had a similar problem? I did a search and found one reference to someone having to bend thier pipe to get it to fit, but no details. Any help is appreciated.

I had the same prob. I had to spread it at the Y section and it went in. No problems since.

How did you bend it? I think i'll give that a shot.

I got 2 pry bars, inserted one into each pipe (where they connect to the manifolds) and had a friend pull one way while I pulled the other way. We just kept bending until it fit.

i'd call cattman and tell them to overnight you a new pipe. 400 bucks for that thing,it should fit.

This is why I don't believe people when they say the Cattman pipe is the best. When you've have modify a $400 pipe with a crowbar to make it fit like it's suppose to is very disapointing. As much as I hated floating Stillen my money 2 years ago for my y-pipe, I knew the sucker was going to fit with no problems.

Well I just received an email response from Brian. Here's a quote:


You would naturally be wondering about variations between one Y-pipe and another, but those are VERY minor, limited to <5/100ths of an inch. The Y-pipes are made on a rigid jig, and are built as one piece from the downpipe flanges up (picture the pipe being built upside down), so its physically impossible for them to be significantly out of dimension.

Makes sense to me. He too suggests bending it a bit. He also says that sometimes it is necessary to bend the OE Y-pipe in the rare case that they are replaced.

Anyway no hard feelings on this end towards the Cattman - his email makes sense and he was very polite and thorough. I'm gonna go wrench that sucker open a little and make it work. Thanks guys.

I've had to manipulate factory Lexus pipes to fit. Exhaust parts r very funny. Think about how many times your manifolds go from 800deg to 60 deg. All the expansion/contaction. It never suprises me when exhaust parts need a little tweak. I only had to bend my pipe about 1/4 of an inch.
