Yeah If "Action Jackson" could enrich it to the sweet spot 12.5-12.8 @ WOT, he'll surpass the 200 whp mark easily.....with a "00" VI I'll say 220whp...Good run Dude I knew your #'s were gonna be good....you do have plenty of torque, which I already knew! See if you can upgrade to a Pathfinder 3.5L throttle body, your #'s should increase as well!

According to nmexmax and aj they think the high flow cat is giving it it's lean A/F, because back when i was running open downpipe I could have sworn the car was running really rich.
Thanks for the props guys (nice guy, cardana, crazy carlton).

The Dyno guys did use the wideband port on the catback right? Yeah if it's taken after the cat the readings could be extremely lean.... Just add a wideband port to your header Ypipe! Then give me a visit....we'll go test the WOT readings.....:{

I finally got around to installing my 3" on my boosted 99 Max. Will drive it Friday or Saturday for sure for a local Maxima meet. I"ll report back with driving impressions. Upon startup, it was definitely louder than my 2.5" Cattman Catback (partially due to the smaller resonator I'm assuming, bigger piping, and non resonated tip)
3" on the left, 2.5" on the right
3" on the right, 2.5" on the left
3" on top, 2.5" on bottom
3" resonator on top, 2.5" resonator on bottom
Resonated tip on 2.5" muffler (nicer thicker wall too)
Non-resonated tip on 3" muffler (thin walled)
3" on the left, 2.5" on the right
3" on the right, 2.5" on the left

2.75" fastcat on the left, 2.5" fastcat on the right
The trailing arm that is 1/4" away from the exhaust.
Tons of clearance to the gas tank...exhaust should have been pushed over a good inch to avoid banging the trailing arm.

Some random pics during installation.....
Good shot of the fastcat and headers
Nismo hangar- (3 total)
Generic Walker hangar from Napa (1 total)
Plenty of clearance over the axle

Very nice Wiz, your tip looks about where mine is. But I have the Stillen rear valence that hugs around the bumper up to the tip making it appear flush. I got those blank flanges to extend it a bit but still haven't had a chance to install them yet. When I do get them in, I'll post some before and after pics.

I was thinking of posting those in your exhaust thread, but figured you see these and pick and choose what you want.

Yes, I have a lift in my garage. Actually 2 lifts; a four post and a scissor lift.
The previous owner bought the car here in CA, moved to New York for 6 months, didn't like NY, and move back to CA. So yes, it spent some time in the snow/salt unfortunately.
I do my own work, when skills and time allow.

Oh, I almost forgot, I just put the 98 (silver) Maxima on the lift and measured the clearance between the Bpipe and the trailing arm... it's even less than what I measured on my 99 Max.. It's about 1/8".
I have an idea of how to fix this problem once and for all. Will let you guys know if it pans out.

Does anyone know the distance between the holes on the stock exhaust hangers? Im going to order a set of polyurethane exhaust hangers for the 3" cattman I just purchased Check them out http://www.rallysportdirect.com/Kart...2009-Legacy-GT I had them on my sentra and the 2.5" exhaust on my b13 didnt move at all! a pia to install but wonderful once they are on there...cheap too...
These come in two sizes - Regular 35mm between holes and long 60mm between holes. The 12mm is the correct size for the 7/16" rod that cattman uses to make his exhaust hangers.

o2 Sensor code after 3" install
Any of you throw an o2 sensor code after the install? I got a code for the o2 sensor after the cat, tried to reset it several times and the code keeps returning. I think I may have gotten some anti cease thread paste on the sensor. It was minor at best.. figured it would burn off in time. Its been close to three months now, I just reset the code and it came right back. Should I just replace the sensor? Is there a way to clean it?? break cleaner etc?? Any Ideas?

I did reinstall it carefully and I don't see how the o2 sensor can go bad by just removing it and reinstalling it. It didn't require any torque at all to remove it, so I know I didn't damage it during the installation. I'll remove it, try the break cleaner and see what happens.
