Building the ULTIMATE 2018 Subaru WRX STI - Part 5


We finally have our own catback exhaust on the market! In today's episode of throtl, we make our 2018 Subaru WRX STI sound amazing with a new exhaust system and blow off valve from GReddy Performance. To start off the episode, Evan and Mickey install the new catback exhaust. After, they install the new blow off valve along with some other parts from Perrin to clean up the engine bay. After all the new parts are installed, we show you how they sound in action by taking the WRX STI for a spin around the block. Check it out for yourself in the video below!

If you have a 2015+ Subaru WRX STI, don't miss out on this chance to get your very own throtl x GReddy Performance catback exhaust. The exhausts are available for preorder right now at the link below!
