Cattman 3" Catback Exhaust - Order Here!
Just my humble opinion, but I think drone is, for most people (with a realistic perspective on the trade-offs of performance parts), irrelevant for a 6MT. Sure, you can select a small rpm range and hear the drone, but its so simple to avoid it with a manual tranny.

). The drone was ridiculous for the first two days then it quiets down significantly.As for why this happens I'm sure someone else can explain the science haha.

after a couple days the inside of the tubing accumulates carbon deposits witch somewhat muffels the sound because it's not reverberating of of hard steel, it makes the walls of the inside of the piping a little "softer".... that also aplies to the inside of mufflers, resignators and catalytics...
I found drone to be present @ 60-70 mph when tipping into throttle trying accelerate, it's not that bad!!!! That's part of the tradeoff for more performance sometimes,....... but I'll be attacking that problem in the next 2 weeks with 2 different products....it's that spare tire recess that acts kinda like a bass drum....I found shifting the A/t manually @ 3000-3500 rpm to sound really sexy as hell....We've driven this car for 3.5-4.0 hrs from Houston, Tx to Lafayette, La at least 3 times....My wife even made the trip once by herself....@ 70 you can hear it a little once @ 75 mph it quiet enough to sleep....The law made 3 videos with in cabin cruising on youtube guys......
Nmexmax call Cattman and notify him of the problem, he'll get one too you but in the mean time an ole school U clamp will work fine.....Good Luck

Damn people come on order these things they say these are the best exhaust for your Maxima! And I want to get mine ASAP so come on !!
Just curious about some things here
...I saw something about this being limited
- Is it still available IE:stock?
- How come I don't see the 3" on the actual cattman site
- How much in total should I expect to pay shipped to Canada...specifically Mississauga Ontario
- Is the demand really high right now , should I expect > 4 weeks for shipping ?
I'd be willing to place a deposit on an order ( if that's needed to confirm ) , the Friday of next week if things work out.

Just thought I'd post a little update on my system. Just last night, I did a rough timing of my 0-60 time with my new full Cattman setup (headers, fastcat, and 3" cat-back). Before the new system, I consistently got rough measurements in the 7's, and now I'm very obviously getting times in the 6's. This is all untuned with an automatic, so I'd say these are good results. I love my Cattman setup. Great quality, sound, look, and performance. Hopefully now I can afford to dyno tune someday......
There's definitely a difference in the midrange for sure.....I still think frrom a standstill my Cattman 2.5" bpipe/Oem rear muffler setup had a stronger 60' er and lit the tires up from a standstill much easier than the 3", but once @ speed the 3" really pulls hard as hell and I measured my 0-60 mph times in the 6 second range once the 3" cb was installed. I really love this setup as well.....

Have you measured the extra airflow with the 3" catback? Can you feel the power increase and is it measureable with your instrument(s)?
Anyhow,
This thing is insane, and well, you know me fellas, I'm the first one to ask for results, first doubter, etc. I question everything.
So, fitment wise my Gen I headers seem to sit further back than the Gen II’s or even Gen III’s. Even when I got my first Cattman B-pipe, it sat further back than I thought it should have. Where the piping turns 90º before the axle, it rests right up on heat shield for the fuel tank.
. Same with this, and of course, it’s larger piping so it's a bit tighter, but surprisingly I don’t have any banging/rattling ... yet. Seemed tighter than it should have been, as in I probably should have seen or heard something, but still have yet to. Yes I did install the piece w/ the welding mark facing the sky nearest to the FastCat. Another plus for me was that my groceries don;t smell as if the came from a 72 Chevy, since I now am rocking the Fastcat, before, no cat.Initial thoughts were WOW. No rasp, and that’s essentially all I care about WRT sound.
So 1st goes through,
traction breaks past 5K, 1-2, loss of traction way more than usual. And of course, I could say since it (fitment was so tight) could have been keeping the engine in its place far better than usual posing more mechanical rigidity. 
Not likely, since after the entire unit was installed, I did notice it was still floating, as it should be. So I’ll take that as a power gain and not a pseudo tightening up, no way that’s possible considering the length of the system and momentum (no rigid braces, etc) and the fact that it’s bolted in more than 1 piece (i.e. better flexibility), no to mention the flex pipe. So no, that was pure power gain.Ok, and I DID see more airflow (~3-4% peak, need to excel some graphs to see the entire picture). I hardly drive my car any more, so the noise might not be so bad. I did at one point remember having insane drone at the same RPM’s with my A32, so I guess I’m used to it. Though this isn’t that bad, and there is no rasp, which is effing awesome.
Alos, I do recall CMax stating that you thought you may have lost a litt,e say for a 60’ .. but, that’s what the 3” MAF housing is for,
. As has been stated for at least the past 5 years, it’s the cure for laggy T-response. Ok shat I’m done. So, take it from me with a grain of sugar or salt, maybe a clove of garlic since I am one of the if not the 2nd most picky about sound on this forum.

Funny you asked, I'm such a slacker, just got it installed last night. Took my time, and it took a few hours after work Monday and last night. Stripped a screw so, out came the grinder, and it would happen to be the one over the rear axle area, what a *****.

testing, couldn't respond to anything on the org for about an hour guys...nice reply NMEX, ur almost back to 100% of yourself.....LOL!!!! My 60' is usually 2.1sec b4 the 3" and ES Motor mounts.....

Yeah well I don't know about you, but I'm 3000ft above sea level. So that could explain why I'm in the 6's. Oh, and those are just my stopwatch times. How do you accurately measure 0-60 time? I'd love to do that. Oh, and you're tuned! I am not.

Screw your 0-60 times what's your 1/4 mi. times so that thread can end with you chasing the OP 13.84 sec/1320ft times.....it's still jam packed! I'll redo my 0-60 times soon and launch it harder than I did to get that low 6 sec 0-60 mph time!

Let's see how long that lasts. I tend to try & stay out of those threads that are itching for my input. 
Anyhow, little update. Went to Lowe's last night to check out some t-stats for the house, (Central air going into today, the evap cooler was FTL).
And well, yes, fairly loud down low but insane sound up top. Once again, I was always jealous reading about when 4AT's broke traction when flooring it, now it's a common occurrence, steering wheel goes crazy, it's awesome, and the insane wheelspin from 1-2 ..
Got a few more rattles and stuff, but strangely enough, not when shifting, no banging.
I was having an issue with it shifting into 3rd, which is fixed now (over run clutch pack solenoid) so I am at about the same time for 1/4 mile most likely. with 19" wheels lol
Oh, and perkman, did you ever drive around untuned? If yes, what was your increase in power/performance when you tuned it. Just wanna know your personal experience. I'm enjoying the added power of my Cattman setup, but I can't afford to tune just yet.
Huh. It seems those solenoids go bad fairly often. I just replaced my solenoid pack for a 1-2 slip/flare, and it fixed that.

I don't know about cattman headers. I got OBXv2 and they have problem for my cattman 3" . They make my exhaust hangs low little. I had to remove the those two plate that goes underneath the exhaust. It makes me worried a little.
