Loved the sound and enjoyed the install! plus the stickers were a great surprise

Checked a lot of YT videos for sound clips. I like the sound, and my neighbors don't even hate me. Was pretty easy to put on. Used a cheap set of ramps from the local auto parts store.

I got my greddy exhaust this week...and Installed it last wed. I like it very much because of its rumble and deep sound.. From this U can hear the real boxer engine of your sti.. Much more louder than compared to my bro(he got the hks one with silencer) ... Very nice and good performance

This exhaust is definitely for someone who wants a quality exhaust that's louder than stock, quiet on highways, but is loud when you get on it. Did not come with a resonator, but in my opinion it doesn't need it. The only issue I had while installing was my drivers side muffler to Y pipe flange hits the spare tire well. Took a rubber mallet and hit the well up a little and it solved the problem. Overall, gorgeous exhaust, great sound, and easy installation with all hardware required included with the kit.

....i love this exhaust, easy to install, came with all the hardware needed and gaskets. First off the exhaust i receive came without a resonator but it states it comes with one, I'm actually happier without it, it has a deep rich tone Greddy is known for, its quiet at cruising speeds but its loud when you get on it. I recommend this exhaust for anyone that wants a quad tip but louder then the q300.

This is what I was looking for. The sound is deep but not obnoxious. Calm at idle and throughty when you get on it plus there is a soft gurgle on release. The sound matches the car more than stock exhaust does.

This cat back bolts up just like any other. The only thing that was unclear was the part where you need to bolt up the mid pipe to the stock j-pipe. I originally thought that you needed to keep the donut gasket on but apparently there's a pretty sizable gap if you do that, and I actually snapped one of OEM spring bolts apart trying to close it. We ended up taking the donut gasket out and using the supplied shim gasket plus some gasket sealer goo to get a good strong seal. No leaks! Everything else was as smooth as butter to slap up. Recommend wiping everything down with alcohol before starting up your car to prevent oil burns and all that mess. Its a big step up from stock, really throaty after 3k RPMs, and deep all around. Just an incredible sounding system, with super quality welds and craftsmanship. I decided to go with this over the muffler deletes due to the fact that when paired with even a catted aftermarket J-pipe, the Greddy SP will contain any potential tinny rasp.... Whereas the deletes just dont care. Anyways, i think its louder than the R400 but a pinch under the Invidia N1. No regrets here.
