  1. Exhausts and Downpipes
    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...
  2. Exhausts and Downpipes
    Hi guys! First post here I recently bought a plm catless dp without any gaskets or other parts. The seller told me I just need to order a 3 inch gasket. Is there anything else I need for the install? Such as bolts, washers, nuts etc OR can I just reuse the stock ones. And what are the...
  3. Wanted Section
    I'm in the Minneapolis region, but willing to pay shipping. Open to other downpipes as well, but would prefer the RV6 catted one. EDIT: Found one on local craigslist of all places...

    So I’ve seen there is the tuning section but I haven’t seen an answer for this question I have, assuming because this is really basic and I just don’t know it. So I have a Invidia N1 cat back + CAI. after I get my coils, I want to get a downpipe to get louder, backfire as well as a little more...
  5. Exhausts and Downpipes
    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?
  6. Mechanical Problems & Technical Chat
    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...

  8. Canada
    Eh! Anyone here buy/install a downpipe on their 9th gen si? If so what brand and type (Catted or Catless) did you get and do you know if you will pass emissions? Also if you have the RV6, how did you obtain it? Did you order it through the RV6 U.S. site, or is their Canadian retailer that I...
  9. Exhausts and Downpipes
    From forum suggestion, I installed my downpipe with a 70a Rear motor mount & 70a upper torque mount and it still cracked. i was on my usual route to work when all of a sudden the car came obnoxiously loud , and I immediately assumed it was the downpipe , I parked and checked and sure enough it was.
  10. Mechanical Problems & Technical Chat
    Hey everyone, I recently bought a used Buddy Club downpipe. Upon installation, I saw the flange for the downpipe simply does not line up with the OEM Catback. When two bolt holes are aligned, the other doesn't. Has anyone else had this problem? Anyone have suggestions? I have gotten it to work...
  11. Exhausts and Downpipes
    I'm planning on throwinng a CT Supercharger in my '14 SI Sedan. I'm hoping to find a downpipe with the cat to make things a little easier come E-Test time. Anybody know of any High Flow Down Pipes with a cat? Would be a great help. Thanks.
  12. Downpipes and Exhausts
    I am about to install an aftermarket downpipe and noticed the top o2 sensor has a shroud around it which makes using a thin walled o2 socket necessary. Is there a certain one you used that worked for this application? Thank you
  13. Forced Induction And Nitrous
    Hey guys, Im new here. I have been perusing many different threads on this forum for a good while now. Lots of great information. I am starting to gather parts for a supercharger setup and will be using the Kraftwerks kit that is available for my 2012 Si. I have an Injen axleback exhaust and...
  14. Downpipes and Exhausts
    so I was wondering if I were to put an exhaust tip on my 2013 civic lx, would it sound like a fart can or even change the tone at all? In order to change the tone, would I need to get the whole exhaust system or add a muffler? I'm not too familiar with the exhaust system, I know, shame on me.

  16. ECU Tuning
    Hi All, I'm going to be purchasing and installing a downpipe on my car in about a month. I was wondering if someone had a Flashpro map that I could use thats tuned for it instead of the basic reflash. I will eventually get my car tuned but wanted to do several upgrades before tuning. I.E...
  17. Maintenance/Repair and Practical
    Ok. So here is my DIY on how to remove the cowl and the various components to gain access to the back of the Si engine to remove the valve cover, top O2 sensor and the downpipe. I do not take responsibility if you damage your car in attempting to reproduce this procedure. Always take your time...

  20. Exhausts and Downpipes
    When the K24Z7 was first introduced, many people were disappointed with the integrated exhaust manifold that made conventional “headers” obsolete. This is especially true since the K-Series platform produced some very impressive performance gains with quality headers. When you look at the O.E...
