Invidia 15-21 Subaru WRX / STI N1 Twin Outlet Single Layer Tip SS Cat Back Exhaust | HS15STIGTP

This Invidia cat - back exhaust is designed specifically for 2015 - 2021 Subaru WRX and STi sedans. It comes with all the necessary hardware and gaskets for an easy installation. The exhaust is crafted from 3 - inch mandrel - bent 304 stainless steel tubing, ensuring durability and corrosion resistance. It features 4 - inch polished slash - cut tips that add a stylish look. With a dual - exit design, it produces a louder and more aggressive exhaust note. However, compared to the Q300, it has a deeper, louder sound and may have drone at higher RPMs. If you only want a slightly louder exhaust than stock, we suggest the Q300. And if you have the stock downpipe, you'll need a product from GrimmSpeed.

Using this Invidia cat - back exhaust is straightforward. First, make sure you have all the necessary tools. Unpack the exhaust and check that all the hardware and gaskets are included. Then, carefully remove the old exhaust system from your 2015 - 2021 Subaru WRX or STi sedan. Install the new exhaust, using the provided hardware and gaskets to secure it in place. When it comes to maintenance, regularly check the connections to make sure they are tight. Clean the polished tips with a mild metal cleaner to keep them shiny. Remember, this exhaust is louder and may have drone at high RPMs, so if you're not a fan of that, it might not be the best choice for you. Also, if you have the stock downpipe, you'll need an additional product from GrimmSpeed as mentioned in the description.
