Cattman Y-Pipe Comments, Install, & **PICS**('not 56k friendly')
I installed my Cattman Y-Pipe on my 2k2 Max Se this weekend. Thanks to PoLo for the tip on spraying the nuts and bolts with WD-40 ahead of time for them to be easier to take off. I had no issues at all with the install. I am fortunate to have an oil change pit in my garage so getting under the car wasn't a problem.
The only small issue was having to remove a clip that the wiring for the O2 sensor ran thru. I removed the one clip that mounted to the bracket above where the heat shield and stock y-pipe bolted to the frame and wire tied it to the wiring for the O2 sensor on the front set of exhaust headers. I experience no SES light.
With a stock exhaust, I heard very little difference in the sound. I even recorded the before and after sound and can't tell any difference. I can tell a bit of a difference in pick up as I roll thru the gears (manual). So, I took it to the track that night (local 1/8th mile). I ran a best of 9.037 seconds at 79.66 mph (which is an increase of 3.8 mph and a decrease of 0.42 seconds over my last times). The y-pipe is my only power adder other than a K&N Panel filter.
Below, I will post pics of the stock y-pipe before removal, the Cattman y-pipe before install, the stock y-pipe after removal, and the Cattman y-pipe as installed. Any comments are welcome.

just installed mine too. haven't driven it yet, but i feel less resistance from the gas pedal when i rev it a little. the only part that sucked was my dremel broke, so i had to use a hacksaw to trim the dreaded bolt and use an open-end wrench to tighten the nut, which is more elbow grease than my elbow will allow, and also had to cut the zip ties for that o2 sensor you mentioned. at least you had a lift, i did this all under jack stands. talk about claustrophobia.

HMMM
is that the new pipe?
what i mean to say is...the rear precat pipe....did he shift everything to the side. it seems like the pipe no longer blocks the 3rd bolt hole. can you confirm this?
glad you like it. 3.8mph is a difference. told you you'd feel it =)

Install was very simple. Took two hours but me and my friend were taking our time. I didn't have a problem with the O2 sensor or the bolt. I guess I'm lucky. Eddie, with a lift and strong tools, that install will be done in 30 minutes.

i have a little dilemma, it's lengthy, so here goes: yesterday, i was able to remove ALL the nuts w/ relative effort. i had some stuff to do, so the stock y stayed on, and i screwed everything back on, but not too tightly so i wouldn't give myself a hernia. today, i put the car back on jacks, and i was undoing one of the nuts from the rear collector, and i accidentally twisted the bolt off! (it wasn't the bolt that had to be trimmed, it was another one.) still, after putting the cattman on, i made sure that the other 2 nuts went on tightly. i finally took her out for a drive, and i can feel and hear vibration up to 2.5k (starting from stop, slowing down to make turns). anything from 2.5k and up, it sounds and feels as seamless as expected. free-revving, i don't feel and hear the low speed vibration as much as i do when the car is under load. can this be caused due to a 3-point flange screwed in by only 2 nuts/bolts? for reference, i have a cattman cattback. any thoughts/input would help (i know, i f_cked up big time here). i'm guessing i have to drill a new hole thru the twisted bolt and rescrew a new one.
