    How's it going guys? Do you think deleting the resonator from my cobb 3" ss exhaust system sound good? Is this a bad idea? Would love the feedback Thanks!!

    Rare Milltek catback for the GR wrx/STi hatch. This catback was discontinued by Milltek around 2020 so it is no longer available. It is one of the more subtle 3" catbacks available, very OEM+. Great if you want a 3" setup that has nice tips and an improved note over stock but you don't want to...

    Does anyone have experience with both of these CB exhaust systems? I have a stock 2021 STI and looking to add some volume without being obnoxious. After a good bit of research and videos I've narrowed it down to these two. Leaning towards the AWE but worried it might be too loud compared to the...

    Here in cali they pull us over if our exhaust is too loud. I have a perrin on my current build (370 whp) and am in process on a bigger setup. Fujitsubo was recommended to me as a good option -- great reputation and the forums seem to agree on the exhaust note. Specifically the Authorize R is...

    Hello, Few weeks ago I had my ignition coils, spark plugs and fuel pump replaced. I also had my injectors cleaned. Vehicle was running rough and very unresponsive before, and I haven’t had any crazy issues since. I might be going crazy, but as of recently, the exhaust sounds a lot more muffled...

    Hey all, I am looking for a catback system for a “stock” 2021 STI that can provide a deep rumble, but produce minimal drone. I don’t have too much issue with price as long as it’s not like $2k+. I’ve looked at AWE touring, COBB, and Borla, but don’t know how badly these drone. Any suggestions...

    Hey there, I’m a newbie to the forum, so hoping this isn’t already a thread, but I had a question regarding an exhaust noise/rattle at high rpms at WOT. It kind of sounds like loose gravel hitting my exhaust briefly when approaching red line at WOT. It’s difficult to tell if it is consistent...

    Hello I have a 2019 sti that I’m looking to finish. I want to get the most fun out of my car while being the most reliable it can be and still get my money’s worth of miles out of the car. Right now I have the Cobb sf air intake+ box and the cat back exhaust. Also I have a cylinder 4 cooling...

    Gents, I have poured over the threads and youtube videos trying to figure which one to get. I am looking to be more on the conservative side on sound, but still want it to be a a good rumble. I am leaning towards the AWE touring, it just sounds so damn good in the videos. What I am worried...

    Hello everyone, I have a 16 sti with a remark non resonated midpipe and boso axleback. I have an intake but still on stock downpipe and will stay that way at least until the summer. I want to know if the tomei is louder then this setup. My guess is the tomei is not as loud because of the...
