Installed the pipe - great fitment. Install was a pain but nothing to do with the production of the y-pipe. It was due to the rusty studs on my cat and precats. The O2 sensor needed to be extended about 4-5in because the stock pipe has a U shape angle going closer to the front of the car. Cattmans does not - which allows for better flow. I am throwing no codes.

The throttle response is better, my sound has improved, the car seems quicker above 3500rpm (I have the VIAS plate) I will be getting a dyno soon, and I have a baseline to compare.

I will post up a video soon. Thanks again Cattman!

 

good man... u should get it dyno to see gains and tuned properly

 

yeah next is dyno - then tune - then nx install

 

keep us posted

 

of course!

 

The cattman y-pipe was my missing link, making the most out of the intake and cat-back.

• Intake alone: small gain, mostly noise. Fun toy.
• Intake and cat-back: slightly more gain, raspy tone.
• Intake and cat-back and y-pipe: lots of gain, deeper tone.

Glad you're happy. Catts sells quality exhaust parts.

 

awsome man, you got headers as well.

 

good to hear, def understand. When i put mine in the time it took was mostly just burning the rusted nuts off the old and removing it.

 

This was the brand new one that he had made. I'm not sure if anyone has one yet.

 

Congrats man. Any pictures of the Ypipe? Pre and Post install?

 

you will prob see 5-7hp with the y

 

why didnt you just buy headers?

 

He is shipping the rest of ours this week. Not sure if I'm going to keep mine or not. Anybody (maybe) want to buy a brand new Cattman 5.5 y-pipe?

 

I thought there wasnt much gain with the y pipe on the 5.5 gens. If there is and this is because of the new design I might be interested whats the price tag on these? I would also like to see pics even if its just of the Y pipe.

 

Where is the video yo?

 

there isnt cause it doesnt remove the precats, thats why most get headers now.

 

if you are really sold on a Y for the 5.5 you can just get the warpspeed, i thought about the Y until i understood the whole precat thing, i actually had a cattman y that i bought from phantomV and i sold it before i installed it, Y for the 5th gen is great, y for the 5.5 not so great but hey, better than stock i guess, get her dynoed to see the gains

 

told ya to sell it headers ftw on a 5.5

 

lls, i never intended on installing it i was tryna make a lil extra $ it needed repair n i got it done fo free

 

i will be getting a dyno and a tune after a while - i have a baseline to compare as well

keep forgetting it lol - i am in the midst of moving to my new house
