Invidia Q300 Exhaust System for 2015 Subaru WRX STI

Blending a high flow, large diameter polished piping design with a full canister, continuous flow muffler, Invidia's Q300 system is one of the most powerful street oriented systems available. The start of the Invidia Q300 exhaust is polished T304 stainless steel which is mandrel bent in Invidia's state of the art production facilities. CNC made flanges are then robotically TIG welded to give exceptional fitment and durability. Lastly, the Q300 exhaust muffler is added to finish the exhaust off. This muffler uses a flat bottom design to maintain ground clearance on lowered cars, high absorption Advantex packing for a deep sporty tone, and dual walled titanium or stainless tips to dress up the appearance of your Subaru WRX STI. Q300 systems work great on NA (naturally aspirated) and forced induction vehicles alike due to the optimized piping diameters for maximum power production with a daily driver friendly exhaust note.
