    Catless downpipe for 9th gen si. Had to get the pipe welded with a new flex pipe. It will fit on your 9th gen ONLY if you have a catback for our platform. The elbow you see on the side is a defouler for the O2 sensor. It tricks the computer into thinking there’s cats and will help you pass...

    Hey Guys, just got my car tuned and the tuner said that my o2 sensor has gone bad and need a new one so I decided to just order a Wideband AEM AFR Gauge online that comes with the sensor. Was wondering if the Wideband sensor the AEM kit comes with replaces the o2 sensor currently in my downpipe...

    my friend sent me a link to the skunk to RR exhaust I later bought it turned out it was for a sedan not coupe need help knowing if I can retro fit the one I have or can it bolt on just would be longer?

The downpipe now has a mean crack in it, is throwing a lean fuel mixture/O2 Sensor cel, and needs to be replaced. I’ve been dealing with the smell (amplified...

    As my name explains, I am new at this. I have a couple of months with a 2012 si sedan and looking to make it sound better and get some more performance out of it as well. I wasn’t sure where to begin though... should I get a downpipe first? Or the exhaust first? Should I get them at the same...

    Hi everyone, I just want to know your muffler modification to your 8th gen civic. Because I'm planning to change my muffler anytime soon but I don't want it so loud. Where others could definitely notice the sound a lot from the inside. Because my girlfriend don't want me to change it but I do...

    Working on getting a custom exhaust rolling for my 2015 Honda Civic coupe r18. I like the borla spitfire exhaust. I'm getting that and a Megan racing down pipe probably, don't know much about resonators.. k don't want droning to occur, looking for a nice deep tone. Any recommendations?

    Hello! I recently installed a Full Race catless downpipe and a 3" Yonaka exhaust. From 2,000 - 2,500 RPMs, I get a distinct 90's Honda, grinding aluminum, $50 eBay exhaust rasp. Has anyone else tracked down a rasp for certain RPMs window and eliminated it?

    Hi everybody! History: I have an AEM CAI and the person before me deleted the secondary cat and welded (very poorly) a 3" home-made exhaust to it. I tuned with Steve at E-Tunez with my FlashPro and was very satisfied with the result. I recently ordered and installed my Fullrace Catless...

    Hey guys, I purchased my 2015 FB6 almost a year ago and I'm ready for my first big mod. If anyone has a Full Race 3" Catback Exhaust used for sale let me know. I'm in Maryland, but can drive around the DMV area if there's anything available.
  18. Exhausts and Downpipes
    Just curious but would the ktuned 2.5" axle-back or any axle-back simply bolt right up to Invidia 2.75" piping? Or would modification be needed, as the axle back was made for the OEM exhaust? Just genuinely curious, don't plan on replacing the N1, but i'd just like to know what my options are...

    Long story short, I got my hands on a brand new Invidia Q300 catback for a steal of a deal (friend totaled his veh before installing it, he's fine, car not so much). Trouble is, I have a 15 Coupe Si and this one is for a sedan. I did a test fit on it 2 nights ago, and by the looks of it...
