Invidia Q300 Cat Back Exhaust - Subaru WRX/STI 2002-2007
Manufacturer Part # HS02SW1G3S
If you are looking for a great way to squeeze a little extra performance from your vehicle, then you will be pleased with the Invidia Q300 Cat Back Exhaust System. There are several performance attributes that makes this an excellent upgrade. This exhaust system has been made from 304 stainless steel and features 76MM piping. The exhaust has also been designed with minimal bends to reduce the amount of turbulence during acceleration, allowing the engine to exhale the exhaust gasses with less restrictions. This means you will have improvements in throttle response, along with increases in both horsepower and torque.
This exhaust will come with a beautiful 101MM polished tip, and the exhaust hangers are welded onto the stock location of the pipes so you don't have to perform further modifications.
New gaskets and hardware will be included to make this exhaust system ready for installation.

I did the install of this on my own. The two piece assembly made this very easy to get the pipe aligned while squeezing under my car. Exhaust came with all new gaskets and hardware. I purchased this to replace the custom made exhaust on my car (Needed something less quiet). It fitted up perfectly with my ETS rotated downpipe without issue. The tone is pleasant and made my mini monster less noticeable on the street. Being catless and having equal length headers, it still growls a bit. Once the wastegate opens, you can't hear this exhaust at all. Thank you Rally Sport Direct for the fast shipping over the last few years!

Q300 is quiet and easy to install, put the invidia bellmouth downpipe with it and all I can say is super smooth. Used two short hangers in the back and a long one in middle, If you have small children or just want to be stealthy this is the exhaust you need.
a great product

This catback exhaust is great. Its not much louder then stock so neighbors wont complain. Its a very nice deep tone that doesn't drown out the car.
Great exhaust, but...

This exhaust is awesome. It sounds great and looks great, but required a little fabricating for my application. To anyone installing this to a 2.5i Impreza, the midpipe is about 3" short. The most cost effective way I handled this was I made an extension pipe from some 2-1/4" pipe and a couple 2-1/4" flanges. Just weld everyting together and bolt the extension to the stock cat pipe and then the new exhaust will bolt in no problem. Tip: make sure to buy another set of bolts and 2 gaskets that fit the 2-1/4" flanges. Also, when buying the flanges and gaskets, make sure the bolt spacing is correct ( about 4-1/8" ). The stock cat pipe has a lip where the donut gasket fits that will need to be cut off and ground down flush to make a good seal.
Perfect except for one issue...Installed on a 2006 WRX Wagon

After getting this installed it sounds amazing, it's the perfect blend of rumble but not being overly loud and droning. The only issue I had (which wouldn't come into effect if you were replacing the downpipe) is the bolts provided to link the mid-pipe to the downpipe are to big and will not fit into the stock downpipe holes. The one's provided are an M10 and the hole will only fit an M8 unless you were to drill out the hole to fit an M10. This is my experience on a 2006 WRX Wagon which may differ from the Sedan downpipe holes. Just be warned that you may need to make a trip to the auto parts store for some M8 bolts and nuts if you are strictly using this for as a catback setup and not a turbo back. Amazing Product otherwise and will continue to order from you guys!
