Add to Wishlist


Invidia's Q300 catback exhaust system for the Subaru WRX and STI sedan provides a great alternative to the standard N1 style exhaust system without compromising power or quality. Traditionally, if you wanted a quieter exhaust system, you had to sacrifice performance to get there. Not anymore. Enter the Q300 series performance exhaust from Invidia. Q300 exhaust systems utilize specially sized resonators and muffler baffles to maintain power output while still producing a deep and mellow touring exhaust tone. Still skeptical? The Invidia Q300 will increase horsepower and torque tremendously all without disturbing the neighbors or raising the eyebrows of any local authorities. The ultimate in stealth power! Invidia exhaust systems include all hardware and gaskets needed for a seamless installation on your STI sedan.

Great, quality product from Invidia that comes well packed and wrapped to prevent any damage during shipment. Install took me about 40 minutes total and it is very easy todo; six bolts, 5 rubber hangers and you're done. Fitment is superb, and the tips fit flush with the rear valence, providing a clean, professional look. The sound is controlled and brings out the distinctive boxer engine exhaust note; a proper touring exhaust for this STI.

awesome exhaust!!!

This is an amazing exhaust that I've had on my 2011 sti sedan for a little over 2 months and love how it sounds! I recently changed to using a perrin equal length header and honestly... I like it even more now! Good quality from invidia as always and def recommend to anyone trying to keep the stock quad tip exhaust look :-);
