How log have you been running yours ? and what RPM do you get the worst harmonic. Some people say they get quieter, I dont understand how that can happen.

I love mine. Had them for about 5k miles. Worst drone is around 2k rpm just cruising

edub370

had mine on for 15 min with tp's.... then took them off and sold them so my ears wouldn't bleed. there is drone at all rpm's and SCREAMED at wot.

mind u, i'm 23 and pretty obnoxious and it was way to loud for me. whoever said it gets quieter was full of it. its not like a muffler where the packing can settle/change over time to produce a different tone. its a pipe... people who say it gets quieter have just gotten used to it

I'm 20 and my dad is 53 and loves it. It has a v8 sound at idle. The only reason it's loud I cabin is because our z doesn't have a trunk, it's a hatch. But to each their own.

now again, mine was with tp's, so i probably had a few more decibles than the average bear

I love the sound I have been hearing with them and will be installing mine ASAP once car is out of storage in approx 2 weeks. I already have the parts. To combat the cabin noise you could always do some dynomat or some other sound barrier in the trunk ara to help quite it down. I might end up doing this.

I also have been reading it helps keep the little annoying wheel well noises out when little stuff bounces around up in there. I always check for damage and there's none but some days those sounds like its hurting it, so I'd rather just not hear it. Lol


Evil sports - are you not liking them now? Or why are you asking if they get quieter? though I don't see how a straight pipe setup could get quieter.....

I've had mine since November and love them. IMO the worst it gets is right around 4k, below or above it sounds fine.

I get a harmonic at about 2800 that will create a buzz in my dash somewhere when its cold out. I wonder if that harmonic is such that it will cause things to loosen up sooner than stock.

IMO, i doubt it will cause anything to loosen up any quicker. If everything was tightened properly at assembly and you haven't touched it; it shouldn't come loose any quicker. Again that is just my opinion.

I agree. I have a different brand of 'short tail', but they are the same design as the AAM's. (I bought them here off the forum -- don't know the brand, but they look commercial quality, not 'home-made')

Except for the muffler deletes, I have a stock 370z exhaust (non-NISMO), including stock cats. I love the sound, but I would not want it *any* louder, so I'd never add test pipes.

I also have the K&N Typhoon intakes -- don't know if they have much effect on the muffler, but I really like the combo of the K&N intakes and the muffler deletes. To me, it *feels* stronger than stock, but I've never dyno'ed it, so I have no facts to back up that feeling.

Cheers,
Kent

That's just the person slowly going deaf from all the drone
