Cattman Headers production Run December 2013
#10
Is there a thread with a sign up list? Also would anyone know if these are for the 3.0 or 3.5? Im looking to get a set of headers and Y for my 4th gen and im aware theres some slight differences between the two.
If hes going to have some 3.0 headers im in it to win it!

I think 95-03 are the same just different y pipes but call him.

$350 for a Y-pipe ..., nice! If I go in, I already have the B-pipe. Will I need a new CAT to make the conversion flow better? His site says the RT cat is NOT available ...? One of my Pre-CATS purrs at about 1800 rpm (annoying) ... Hope to install does not drive me Mad with any rusted bolts ...!

Cattman Site: " 1995-2001 Y-pipes eliminate factory-installed “pre-cats” and are not intended for use on public roads or highways. Primary catalytic converter remains in place and functioning normally."

If your willing to pay 350 for y-pipe then you should save up a little more money and get the entire headers and y-pipe combo. Trust me. Ive have a y-pipe, shorty headers with a y-pipe. Then two sets of cattman header and y-pipe combos. It is a hands down no comparison difference.

Y pipes:
95-98 are all fed spec.
Some 99-01 are fed spec.
Some 99-01 are Cali spec.
02-03 is different again.
Fed spec has both pre cats in the y pipe. Replacing y pipe eliminates both pre cats.
Cali spec y pipe has 1 pre cat. Only one (of the two) is deleted with a y pipe replacement.
02-03 y pipe has no pre cats in it.
Headers replace the y pipe in all cases, and thus, replace all the pre cats no matter what.
95-03 headers are all the same (except 02 bung and EGR Ports.

Not to try & undercut Brian's business. I posted this here to avoid the hassle from bargain hunters that don't realize the value of Cattman's.
Since I no longer own my 2001 Maxima. I have a set of (gen 2 w/EGR) headers/y-pipe/fastcat/gaskets & etc. (i.e. R-O2 sensor extension cables).
BNIB sitting in my garage, coated w/ VHT flame proof 2Kdeg.F aluminum/ceramic header paint.
Serious inquiries ONLY please, via. PM.
