Finally getting my Cattmann Y-Pipe installed tomorow. Are there any specific guidelines I should mention to the muffler shop such as gaskets? Any advice is appreicated. Thanks!

Could you ask the muffler shop if having the y-pipe is legal? I'm still wondering about this before I get one for my Maxima.

 

I dont see what the big issue here is, I mean Nissan Dealer would mind, but a muffler shop wont say nothing, they wont say much even if you ask them to remove your cat and install straight pipe.

It's a moral issue for me. Doesn't matter if a shop will do it or not, what matters is what's right or wrong. No moral judgement here, just personal beliefs about polluting just to gain 10-20HP.

 

The Y-pipes are NOT legal in CA. It removes a cat which is a big no no. The car will still pass smog after it's warmed up but it's still technically illegal because the emmisions equipment has been altered or removed. But don't sweat it, you'll be fine. Y-pipe was the best mod I have done so far.

 

Be sure that they replace the gaskets with the new gaskets you got. Also, ask them to use anti-sieze on the bolts and O2 sensors... They may need to unbolt the cross-member underneath behind the main cat to fit the y-pipe in. The Cattman pipe is a tight fit, but everything should line up fine.

 

hey bro guess what? i finally ordered my ypipe

 

congrats! which one? Cattman?

 

Yep thats why i was asking about the rt cat thing. if i should buy that too and install it at the same time. but im gonna leave that alone.

 

cool


instead of the cat, get a CAI

 

but i JUST got a pop charger last week

 

oh... ok thats cool then....


how about a UDP?

 

i was thinking about that. i know the effects it has on the auto, but is it good for the manual as well? there are mixed feelings about the udp so im really not sure if i should get it.

 

well then, save up a little more and get NOS you know that works

 

trying to get max hp N/A. no boost for me.

 

I just got mine today and was wondering if anyone knows of a good site that has detailed instructions on the installation. If so, it would be greatly appreciated. And yes, I did a search, got nothing helpful.
