SRS catback review
Althogh it hasn't been driven more than 30 miles, I can say that it's too loud for me.
Finish is impressive, fitment is impressive. Sounds great @ wot and idle. Also sounds good when reving w/o load. Daily drive is the issue. Going uphill for example @ about 55 mph and 2k is hella loud. In cabin drone is unacceptable.
For the money, it's a quality unit, if you don't mind the noise. For me though, it's just too loud and I'm looking into ways to quiet it down.
No rasp and no fart though.

Weld bushings onto it. Ive seen where some companies are doing this at the factory; last I saw was either an HHR or PT Cuiser exhaust. Drone/vibration is transferred from pipe and into welded bracket, then absorbed by rubber "bushing."
A larger resonator might also help, if that's an option.

Any glass pack-style resonator is going to drone no matter how big it is. It's just the nature of the design.
That being said, if you want to reduce the drone, you might consider installing a chambered resonator before or after the glass pack.

Nope. I doubt you will find a performance catback for the Maxima that doesn't drone without modification to the system you buy. Especially if you have an autotragic. Performance exhaust isn't for everyone. If noise it a deal breaker for you, replace with OEM. You can't go wrong.
#10
You were warned. Compare the size of the OEM resonator to this resonator and you'll discover the biggest culprit of that drone. It's fairly inexpensive to replace the resonator and you still come out ahead of most catbacks. It does mellow out some after more mileage but the drone never goes away. In defense of the SRS though, I believe the drone is just as bad with the Cattman 2.5" catback.

Spock, this is with the Cattman Y right? I installed a Megan catback with my Y and initially it was too loud also. I replaced the metal intake tube on my SRI with the stock hemholz chamber, and that quieted things down a lot. It quieted down further once some carbon had built up, and now it's quite mellow, with no irritable drone (6 speed), but has a nice growl. If you have an SRI without the stock chamber, try it with.

^ This is true.
Once the catback breaks in, and the fiberglass in the glasspack starts to settle, things will quiet down considerably.
However, that quieting down phase will eventually end, and then things will start to get louder as the glasspack breaks down. However, that's years down the road. Your catback would probably rust out before that happened.
Also, for what it's worth, the SRS catback with the OEM axleback in place, with the Y-pipe will give the car a nice, quiet, yet tuned sound.
I remember going from eBay Greddy knock-off to OBX headers --> testpipe --> 2.5" piping from the eBay exhaust --> stock axleback. The sound was actually pretty nice.

It seems to some degree, drone is inherent ALL peformance catback exhaust. I've listened to MANY sound clips of exhaust setups and SR*S is among the most quiet & pleasing tones in the bunch. I don't find it objectionable, but that's my subjective opinion. From the start I mentioned the possible need for a larger resonator. In all fairness, no drone is a lot to expect from a 3"Dia/16"L resonator. I maintain, SR*S is a great value in price/quality/sound, despite any criticism to the contrary.

I'm disappointed you're not satisfied with the SR*S. That said, I'm VERY happy with mine and wouldn't have recommended it otherwise. Plus, I posted a detailed review of my SR*S here. http://forums.maxima.org/8249660-post92.html As a reference prior to purchase, for others to make their own decision.

Rowing the gears on a 6MT results in a different overall perception of exhaust tone than a 4AT would, that's true.
But it's not that great of a question, since spock drives an Infiniti I35. MT swaps into the Infiniti aren't exactly commonplace.

I just went to the dragstip and all my friends like how it sounded. Overall It's a great exhaust for the money

but not impossible... so to not ***ume i think it was a good question... anyways autos does drone more than 6 ot 5mt's... not even a cattman catback would save that

I think so & the 4th gen exhaust has a single 4" (potato launcher) muffler tip.

Relatively stock I35 = auto transmission. Realatively stock = NWP spacers and a SRI.
First step is to add a 22" resonator. That probably won't be satisfactory but it's relatively inexpensive.
When that doesn't work, I've been offered a G35 muffler from Tuner. A bit of fabbing, about the same total cost as a Cattman and it should be all good. Except for the fact that it's not a Cattman.
If not, I'll rip it all off and install Walker or Bosal and pout until I sell the car.
On a positive note there is zero rasp and zero fart back when you let off the accelerator. Also, when pulling away from a light, easing into 3/4 throttle quickly, (rather than standing on it), the tire(s), break loose @ around 4700 rpm. It didn't do that b4.

That should help out quite a bit. Magnaflow makes a wide range of resonators in different lengths, pipe diameters, and case diameters. Another thing to consider is fitting two of them on there. You would have to measure your pipe, but if two 22's don't fit, then perhaps two 18's, or whatever is needed to fit as much resonated area as possible.

You'll never fit more than 1 22" resonator in there. Unless you could squeak a 16" or so in where the pipe crosses over to the pass side. A 22" body, 28" overall length Magnaflow is on it's way. It's a gamble, (again), but I hope it helps. If I could reduce the decibels by 30% , which is about how much longer the 22" is, it could work.
Then again, I don't buy lottery tickets either.

a 22" resonator wont help.. ive tried this before... spock just simply replace the resonator for a 30" resonator if it really bugs you that bad, n if u arent using stock cat, install that back too.. it will help ur drone tremendously idk about it being fully eliminated though but dang near
