REVIEWS & CUSTOMER MEDIA








Performance-- really light-weight and has smoother flow. Also has a really nice and loud rumble Ease of Install-- Pretty straight-forward. Only use the DP to mid-pipe gasket if you have a converter or else you will get an exhaust leak. You can reuse the OEM donut gasket to install. There will be a ~0.5" gap between the dp and mid-pipe but its okay; there will be no leak. Value-- Really affordable for a good exhaust. Greddy is a well-known brand world-wide. This exhaust is hard to get as it is always back-ordered. That definitely adds value to it. Quality-- The whole exhaust system is welded with quality and precision. Axle-back pipe hangs a little lower than any exhaust system due to its angled design. Overall, this catback is a great purchase and has a unique, classic look for our VA chassis.
Overall I'm really happy with this exhaust, especially when considering the price point. For under $500 you get an awesome piece from Greddy that bolts up with ease and sounds/looks great. With the stock j-pipe you get a nice deep tone, a few cracks and pops, and it's not too loud. My only complaints would be that it drones a bit around 3000rpms and that it's hard to confirm fitment with a lot of aftermarket diffusers due to the large muffler and aggressive angle. It didn't ship directly from RSD, but it arrived much sooner than I was expecting.
When does the money get taken out for the product ? And how long does it usually takes to ship the item?
Exhaust seems to be pretty good quality considering the lower price. Packaging was very poor. The exhaust itself was bubble wrapped pretty well but there was just little squares of styrofoam tossed in loosely so both pieces ended up moving around a lot. There was a flat spot on the tip. I'm coming from an Invidia Q300 so it's quite a bit louder. Classic STI rumble! Not sure if the tip is the wrong size because where it bolts to the muffler is not flush. There is quite an angle to the way the muffler sits, but I like it. It's also very light being a single exit. Check out the pictures and video. Besides the packaging and damage, I love it!

Q: 2017 STI Tucker2020STI9 months ago
Will this bolt right up to my grimmspeed limited downpipe?

A: We do not test fit of our products with other aftermarket products. However if the Grimmspeed downpipe bolts up to your factory exhaust then there is a good chance it would. We recommend checking with other users or sources before purchasing our exhaust system.
