I did a search and really couldn't find an answer to this.

What kind of HP/Tq gains can you expect from a Catback exhaust?

I'm looking at having a shop do a custom Catback w/ 2.5" piping going into Remus mufflers.

I know the headers/y-pipe is where a lot of power is...but unfortunalty these aren't available for us.

 

The y-pipe is coming up like.....NOW Within next week or so they should be shipping out if they are on schedule.

IF the bends are precise, then you should expect somewhere around 10-12whp, I'm basing this off of Cattman's cat-back with 2.5'' piping and magnaflow mufflers, so it may be a little different with the better flowing Remus mufflers.

 

Are you talking about the cattaman y-pipe?

What kind of HP are they expecting from that? What are they running...bout $300ish?

 

I found the price but not expected HP.

"NEW Cattman Y-pipes for 04-06 Maximas w/ 5-speed auto transmissions; due for release in September, early orders being taken now; reg. price will be $379.99, with FastCat catalytic converter $579.99, introductory price 349.99, w/ FastCat $524.99"

I wonder how loud this thing is. Guess I'll have to wait and see.

 

I was referring to the actual Cattman cat-back exhaust, not the y-pipe.

The y-pipe adds very minimal to almost no sound at all and it also adds about 10whp. Check it out on the 6thgenmaxima.org

thanks!

I really need to get one of these!

 

Anyone have any pictures of the Cattman exhaust on a 6th gen?
