I highly recommend this exhuast. It's my first but I've been into cars for a long time. I originally narrowed down my search to the ETS Quiet and AWE Touring. I was searching for a quiet exhaust so I wouldnt draw too much attention when hauling ass. When I saw and heard this exhaust I had to have it. It naturally produces the snap crackle pop without forcing it in the tune. I've been learning to queue it up while driving. It happens when I least expect it but that's because its still new to me. I've had it for a month and I love it so far. Its quiet at low RPMs but can get somewhat louder than stock at high RPMs. 310WTQ and 290 WHP tune done by English Racing. Upgrade List:Grimmspeed Boost Control solenoidProcess West VerticoolerAeroflow Dynamics F1 single exit exhaustETS 3" GESI downpipeGrimmspeed Turbo CastGrimmspeed Bypass valveGrimmspeed Charge pipe(found out the verticooler comes with one after I bought this, so don't buy an aftermarket charge pipe)Next Upgrades:Ethanol injection systemCold air intakeBig turbo from FPCompetition Street MPC twin plate clutchThis should all get me 500whp.

In the past I got the invidia R400 and it was great but with highway drone. This one is far better and with better sound. I would highly recommend!
J
Sounds really good with my invida downpipe. Crazy light, compared to my remark mid to subispeed muffler deletes.

Had for a year, quality still stands. only put 3k miles on it but still. As with a single exit you lose the sympathy of the quad but the tone is lovely. I’ve paired this with a GESI catted DP from MAPerformance and Cobb SF intake w box among many other engine mods that don’t affect intake/exhaust note. It’s loud but not necessarily SO loud. The muffler limits it from sounding like A turd in a straight pipe mustang or tin sound of a civic. Aggressive driving will garner mild pops and bangs but light throttle it won’t pop and bang. I don’t have some turbo killing Burble tune so make your own assessment on that. It’s light and what I was looking for I’ve always liked the JDM single exit style. Oh and 4/5 for the fact it’s not a true 3in where the resonator is deleted and also the gasket it comes with is a doughnut. Didn’t use the gasket for my DP.

Probably one of the cleanest and best sounding note exhausts I’ve had on an ej engine with stock down pipe. Some pops and bangs can be heard too which was a plus. Excited to hear it with my Cobb catted downpipe I’m putting on soon.

Easy install and perfect fitment. A little WD-40 goes a long way on the rubber mounts to loosen things up. The tone is beautiful I break necks everywhere I go and get plenty of pops and lots of low end throat from the back end. Makes the mustang drivers drool. Weight reduction is superb. If you are looking for an extremely high quality exhaust that brings the boom and cuts the fat, this is an outstanding choice. Wish I could get a sponsorship from these guys I would dip the Sti in Aeroflow all day long!
