Invidia Q300 Cat Back Exhaust Subaru WRX / STI 2002-2007



Add to Wishlist


The Invidia Q300 catback exhaust system for the Subaru WRX and STI sounds as good as it looks. The Q300 features mandrel bent 76mm stainless steel piping and a free flowing oval style sport muffler to provide better exhaust flow for improved performance. Bolting up a Q300 to your EJ25 will allow your Subie's sonorous exhaust note to come through loud and clear when you want it to, without producing harsh or overly loud overtones; the perfect choice for those who want great performance with an exhaust note that won't wake the dead. The Invidia Q300 exhaust is designed with a polished rolled stainless 101mm tip for a stealthy sleeper appearance.

Specs:76mm stainless steel piping / 101mm (4 inch) stainless steel tip

Great product as always

I have the Invidia Up-pipe on with this cat back and a no-name downpipe. Fitment is perfect, install takes about 15-30min, Sound is more tame than most catback exhausts out there, noticeably quieter, and no noticeable drop in power(if any). You will not be disappointed with this purchase. I do recommend the grimmspeed exhaust gaskets for this, the supplied ones will burn out quick.

Had this on my car for about 15k now, and i love it. Quite at idle, but sounds like one mean machine at WOT, a lot of compliments so far. I love it, thanks Josh for supplying such great parts at great prices! Buy this if you want a stock looking exhaust with a great sound but daily driveability!

Great product from a great vendor!

I just recieved This product today and installed it on my 06 sti. I was looking for an exhaust that had good performance but was not going to get the attention of every police officer in a 5 block radius. This was exactly what I was looking for. The sound is great. It nice and quiet when I'm just driving normally but when I open it up it screams boxer rumble. It has a nice deep tone to it at all times. I'm very happy with the weld quality and the fitment To my crawford downpipe as well as the sound. And no review would be complete without mentioning how great the service was here at Josh was great to work with. No other company I know of will get back to u at 1am about your questions. I ordered this product Monday and it arrived Wednesday. I can't say enough about how great the product and the service was. 10 stars. Thanks Josh.
