The Cattman Y-Pipe for the 2002-2003 Nissan Maximas are sweet. It is an exact fit with no problems on the installation. The only thing you have to do is extend the 02 sensor wires which took a little time. I used header wrap to isolate the wires from heat and used hay wire around it. Check it out and let me know what you guys/gals think....

This Y-pipe is da bomb! Sound is unbelievable!

Very cool. Nice job on the writeup and pics. I'm sure many, like myself, really appreciate you being able to stop from actually working on the installation to take pics so the rest of us can learn from your example. Link added to favorites.
Thanks

Nice write-up and congrats on getting it on. Told ya you'd like the sound.

 

looks very nice, but how bout some #s ? why not headers? i’m am also worried about legal issues like emissions, would a y-pipe provide reasonable gains wile keeping my ride legal? would i pass with headers???

Looks clean. How long did it take you for a complete installation?

 

Nice write-up, looks like you guys never had your hands full. The sound is nice, with a stock exhaust still retains oem sound and a stab of the throttle up top is very satisfying as well. With my berk and catt ypipe, she screams up top. How much heavier was the stock ypipe than the catt ypipe would you say?

BTW, don't expect any performance gains on the bottom end from the ypipe. It just gives the car longer legs up top.

 

looks great except for one note....you do know that the O2 wires are held by some zip ties on the upper portion, by the manifold. i disconnected them from where they were held and the O2 reached it's new location easily....no cutting here.

other than that, cool pictures. glad you like it...it is top quality.

 

Great pics! Another note, you can just dremmel down the existing bolt and use the old nut instead of removing it completely.

 

I was tired last night loaded the pics on cardomain.com. I have notes that I will be adding tonight. Thanks for all the replies

Thank you Lithiumax

^triple post!

 

I can vouche for that!!! Since getting the Y-pipe, my Max pulls MUCH harder on the highway. EFFORTLESS ACCELERATION!!!

 

Nice write-up and pics.... I will get there some day....

 

Just got mine in the mail today!
Cant wait to install it.

 

man that looks nice.... must sound nice... dave did you get the Y-pipe in a GD?

 

I took it for a spin, and it feels good ! ....... It will be a bit loud for some of you guys' taste. You all complain about noise all the time.....

 

Yes I did. I received the pipe in less than a week!

 

I thougth the o2 sensors are only moved/relocated on the headers only!!
