    Question for you folks.

    On my 2.0 Accord petrol I've currently got a custom single exit de-cat back sports exhaust setup with a silencer in the middle. It will be removed as I am going back to near standard as possible with the sound and music it currently makes to hardly any noise at all. I was given an option of making my new setup as a twin exit which I've never had before or sticking to the current single exit. Other than visual purposes IMO and a little bit more moola would it affect the performance in anyway compared to a single exit? Your reasons whether for or against would be much appreciated. I'm stuck in between a rock and a hard place at the moment.

    Cheers

    Single or dual both seem to work looking at the comments on that thread. I'm still confused bud :lol:

    Personally I'd run a single exit on a K20A6, because the flow gains won't translate into noticeable power - the difference between a 2.25" single and a 3" dual on your car without tuning I'd assume would be 1-3hp. However, duals look better IMO :Laughing:

    EDIT: All comes down to price really, duals won't harm and subjectively look better - there's no real gains over a single on your engine though.

    Interesting. I wonder if anybody else with a K20A6 has ever though of doing this. I guess I'll decide on the day what matters the most. Visuals or money. Cheers though
