I have a choice with my test pipes... Resonated or straight. (AMS brand) anyone know the difference eg way to noisy, performance etc.
100% agree with the above. Loud, raucous exhausts may produce some amount of "street cred", but they soon become unbearably intrusive(when the initial excitement wears off).
I also have resonators and still have exhaust drone, Iv got a2zed putting in a centre muffler now to help with the drone
To echo everyone else, resonate. I had mine removed because of split welds as a temp fix due to being unable to afford replacements at the time. It sounded awesome - for the first 30 mins. After that I made it a specific point to not travel on roads at the drone speed where I could because I couldnt take it. Trust me when I say its NOT the same thing as an awesome loud exhaust.
Ok experts... 3" split dumps, 3" front pipes, 3" input into cat with 2.5" output (100 cell cats) 2.5 UAS x pipe to magma flow hot dogs.... You think this will drone ?
My Z isn?t going to be my daily but I can?t handle drone... might invest the $100 I save from taking resonators out into a better stereo. Or not... resonators it is! Twin 2.5 inch cat back will be loud enough
Drone is to do with the frequency (harmonics) of the exhaust at certain rpm. You realise resonators do nothing to alter this?
I've got magnaflow twin in twin out centre muffler, magnaflow oval twin tip rear mufflers, 2.5" mandrel bent 304ss pipe and it's fine. I put it mostly down to the centre muffler. Heard cars with only the rear magnaflow mufflers and it's stupid loud.
I've got just the magnaflow rears with a magnaflow x pipe in the center , it's been done with decent thick wall stainless and I don't find much drone, compared to the previous modified standard system it's great , altinator likes it too seeing I don't have to have the stereo just up to distortion
Resonators on a testpipe will not increase the severity of the drone. It may even contribute minimally to reducing drone but nothing of great significance. I have the AMS resonated 3" - 2.5" testpipe and I have drone. Previous to that testpipe I had a 200 cell cat in my other testpipes and I had drone with that as well. Common to both those testpipes was my catback. I installed some inline resonators into my X pipe and I noticed an improvement in reducing drone. I can see how the UAS or MagnaFlow muffler-type X pipe achieves significant gains in reducing drone. Here's some good info from here - http://www.300zxclub.com/showthread.php?t=202092 Another example of SBR (Side Branch Resonators). I would love to see this kind of tech implimented for our cars.
