AR Downpipe Install w/ Harman Motive Exhaust
I wasn't going to post a review on my downpipe install because there are already so many out there, but I couldn't help myself because of how smooth and unobtrusive the install has been to the car's daily driveability.
I used to have an Arqray axel back exhaust which I can with a secondary cat delete and the ultimate racing downpipes. There was noticeable drone anywhere around 2k RPM and the car was just loud - by that I mean it wouldn't really sound like anything until I was high up in the RPM range. The AR dp's with the Harman Motive exhaust is super smooth. There is almost no drone. In fact the car, after it's been warmed up, seems like it drones less than before the addition of the dp's. I couldn't be happier with the install. The car itself does not seem much louder either, except at initial start up. The only issue with the car now is the smell, but that is to be expected. I'll see how long I can bear it and maybe add some 100 or 200 cell cats to the exhaust, but honestly, I'm hesitant to do so because of how perfect the system feels right now. My only real concern is that the car actually feels like she's lost a little bit of power because of how smooth everything is running. I'll have to do a little more driving and datalogging to find out for sure.
