On a 1-10 scale of sound 1 being stock and 10 being v8 mustang loud its a nice 6.5.

Not too quite but not too loud. Absolutely live the exhaust note. Nice and DEEP!!

Perfect!

Fit, finish, sound, and performance. I'm a very happy customer.

The right ticket

Dustin williams led me to the MAPerformance exhaust kit and I was not disappointed. This kit sounds great and not over the top. I live in California so I didnt want anything extreme. I'm extremely happy with it!

Great Cat Back, Bang for buck!

The install went well until I got to the muffler and Y pipe connection. I was told they kitted the first rev with 3in to the mufflers. But found out it is actually 2.5in at the muffler connection. Of coarse MAPERFORMANCE got me fixed up. But just check your parts before you got to install them, I got stuck and had to go buy them while I waited for the correct clamp to be sent to me.
All in all.
Great exhaust system low level isn't loud and that's what I wanted. When you open it up you can hear the car come alive! Great addition to my '18 WRX. If your looking for a clean sound but still want that popp from a hi rev this is the kit to get.

Awesome sound!

Bought the catback no muffler and installed. At 1st it was a little higher pitched than I wanted. After a little time it got deeper and the exact sound I wanted! It also got slightly more throaty after installing MAP intercooler and charge pipe! It sounds loud at start up then calms down until you give it some speed. Then it gets loud again! Well worth the price!
