18 WRX with Tomei
First, I really want to say delivery is very fast. I only waited for 3 days and got this beautiful Catback exhaust. When I held it, I have to say it is very light. I think it is most important to me. MY idea of getting my car faster is to reduce weight. Therefore, yesterday I installed it on my 18 WRX, which was quite easy. I spent an hour to take off my stock exhaust and half hour to install Tomei. The sound is really nice, not too loud. Really awesome sound! If you like JDM, go for it. 5-star stuff.

So after much debate on what cat back I wanted I was between the q300 or this Tomei. Needless to say, I couldn't say no to the titanium. I know the q300 and this are on two different spectrums of loud and after having a couple quiet cars it was time for some decibels. Also, I live in Anchorage, AK and shipping items up here can get quite expensive. With the weight of this (or lack of) the shipping charge was half of the q300. I feel I made the right choice for me. This cat back is beautiful. It's a real shame that it gets hidden under the car. Welds are top notch as is the fit. I installed this with the Grimmspeed stock downpipe to aftermarket cat back adapter and no leaks after driving the car 10 days. It is loud, as any canister type muffler is but does it sound amazing. Cold starts (as in 0°F) are loud, I kind of feel sorry for my neighbors as I live in a condo. But once warmed up it is no louder than the SPT cat back with Cobb downpipe on my old 2011 WRX. Driving I wouldn't put it at obnoxiously loud but you don't forget it's there. On the highway cruising at 65mph it is low key-ish, kind of like how it is at idle. But, soon as you give it any throttle it opens up a bit. The wide open throttle sound this makes is nothing short of music. It's quite addictive to hear and needless to say, my mpg suffers from me wanting to hear it. I put this on my 2014 STI. Only mods are Cobb downpipe, Cobb intake with box, and this cat back. I had the car dyno tuned at my local tuner (with only AWD dyno in the state) and car made 290whp/301wtq on our 90oct premium. RSD offering another great product. Highly recommend if you don't mind annoying the neighborhood :-)

I installed this on a 2019 WRX STI and it sounds phenomenal! It coaxes out that low, throaty boxer rumble and sounds great at any RPM. I haven't noticed any drone at highway speeds. It can get riled up quite a bit during cold starts, but otherwise it is not obnoxious. I will admit that I was initially hesitant to make the leap to single exit, but wow, I am so glad that I did! One final note: MAKE SURE TO PICK UP A "GrimmSpeed OEM Downpipe to 3in Cat Back Adapter" for installation on a stock STI. You will need it.

This exhaust is a work of art. Beautiful in every sense of the word. I’ve heard of cars with Tomei, before but never with my setup (Killerbee Coated headers/catless downpipe), so I was skeptical of the sound it would make. I bit the bullet and replaced my Q300 with this catback, which experienced horrible drone. This exhaust is A LOT louder, but the drone is gone, or diminished when compared to the Q300. Cold starts will definitely annoy your neighbors, but once warm, it’s not too bad. When I set my cruise control at 65/70, I can actually enjoy a conversation with my wife, which I couldn’t do with the Q300 due to the DRONE. WOT is a beautiful symphony with my header/down-pipe combo. To be honest, I still haven’t tried the silencer. Maybe I will this morning. While installing, line everything up first, prior to tightening. Stock hangars work fine with it also with minimal or no noticeable movement while driving.

Took me awhile to decide what exhaust to get but I’m glad I finally picked this one. The exhaust is perfect. It was easy to install, looks great, and also sounds great too. Also the shipping was insainly fast! I highly recommend this exhaust.
