Good fitment. Looks great. The sound is nearly orgasmic. Couldn’t be happier. Car drives much better, no tune. Overall heavier than stock and I prefer using stainless hardware over the hardware they supply. Well worth it, excellent choice.

The perfect sound, with super gorgeous big quad tips and blue Ti finish! I had Nameless deletes before and they sounded great, but too loud for daily driving and freeway cruising. This Q300 is perfect! Nice deep rumble on cold start and at idle. The deep, sporty rumble is there at low RPM's but actually gets less loud once you get above 3500-ish RPM's, which is great. On the freeway you still hear it for sure, but it's not the annoying drone like some other exhausts have. Only crap thing is the pipes were greasy and full of metal shavings (???) on the inside. RSD shipped the exhaust fully wrapped and sealed so I know it's not their fault... Invidia if you're reading this, what the heck? See pics below. Still very happy overall because the OUTSIDE of the piping and mufflers is beautiful. Definitely recommend!

I originally got the R400 exhaust and that was way too loud for me. I sold that one and gave this is a try. This exhaust is loud enough to hear a nice growl, but won’t annoy you during your daily commute. Both Invidia exhaust fill up the exhaust outlet in the back very well and look amazing. My younger self would have stuck with the R400, but now being in my 30s this is the perfect exhaust for me. My exhaust was missing some install hardware, but rallysport customer service is always great and Invidia was very responsive as well.

I got the q300 after a year with a nameless muffler delete and catless downpipe. My Wrx was really loud and I had gotten pulled over by police just for that. I decided to go with the q300. It’s perfect, it’s quiet when you want it to be and loud when you get on it . I imagine it’s pretty quiet with a stock down pipe but with an aftermarket dp it sounds awesome! It has a deep rumble to it and it looks amazing with my blue tips. Overall very happy and i feel like it increased my Performace though I’m not sure

After a year with a cat less downpipe and nameless muffler deletes and getting over twice for my “modified exhaust” I decided to go with the q300 because it seemed like the quietest one. It sounds good with the cat less invidia catless down pile as a good rumble to it. Still pops, and it looks sweet with the blue tips with my WRB. 8/10

A: You would need an adapter from the 2.5" downpipe to 3" catback. The tip material wouldn't effect sound.
