Invidia's new Q300 catback exhaust system for the 2008-2011 STI 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 has been dyno graphed to gain 17hp and 5ft/lbs of torque on a 2008-10 STI, 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 08-10 STI.

If you are looking for a top-quality catback that is quieter than the N1 series, this is the perfect choice.

This exhaust has titanium tips not pictured.

Adorable, well-made suit—perfect for special occasions 🤵✨
This suit exceeded my expectations! The color is beautiful and looks even better in person—perfect for weddings, parties, or any formal event. My son looked so sharp and received so many compliments. The fabric feels lightweight and breathable, which is great for warmer weather. It doesn’t feel stiff or uncomfortable, so he was able to move around easily all day. The set comes with everything you need—the jacket, vest, pants, and tie—making it a great value. I also appreciate the adjustable waistband on the pants, which helped get a better fit. Overall, the suit looks very polished and high-quality without the high price tag. Only small note: since it’s linen, it can wrinkle a bit, so you may want to lightly steam it before wearing. Overall, a fantastic outfit for any formal occasion—definitely recommend!

Sharp Linen Suit with a Breathable Fit for Summer
Size: 5, Color: Black
This 3-piece suit is a solid option for a summer wedding or any formal event where you want a kid to look sharp without them overheating. The linen material is high quality and feels much more breathable than a standard polyester suit. The jacket, vest, and pants all fit true to size and the stitching is clean throughout. I was impressed with how well the fabric holds its shape without getting excessively wrinkled after a few hours of wear. It’s a grounded, well-made formal set that balances a professional look with the comfort needed for a child to actually move around in it.
