  • b6t exhaust opinions wanted

    I am needing to get my exhaust done sometime this week or weekend, and I went out and looked at it today. The downpipe from the turbo measures out at 1 3/4" pipe at the cat flange, and it just happens that my exhaust has been previously redone to be 1 3/4" pipe too! It was straight piped to a stock style muffler with only one flange right in front of the muffler.

    I definitely want to add a flex pipe, and at my disposal is a 2" cherrybomb and a couple of OEM 03 Harley davidson softtail mufflers. The inlet measures 1 7/8" so either my current pipe will slide right in or it will be close enough I can butt it up and weld it. Should work out pretty good.

    The harley puts out about 70 horsepower and uses two mufflers, so I figure trying to cram twice the power worth of airflow through them will cause them to get a little loud.

    I have to have the wideband @ 30" behind the turbo, the instructions say 24-36" but 30" is putting it between the firewall and steering rack @ a 15* angle, then a flex pipe for 1' which is exactly where the first hanger is supposed to hold it.

    I don't know if I should use the cherrybomb as a midpipe to try to quiet it down, if I should just use one of the harley mufflers, or if I should Y pipe it at the flange and make it a dual exhaust at the rear axle?

    What do you guys think? I really want to use the harley muffler(s?) because they have catalytic converters IN them and I don't know anybody else running harley mufflers on a festy even tho I know it's been done before.

    Do you need a nice stock B6T Downpipe. You can have it if you want. Really nice condition.

      nah man I got one with the engine, thanks tho! I'm going to end up hacking mine up pretty bad by cutting the old flange off for the stock cat/midpipe, probably even go ahead and cut the heat shield off too before it has a chance to rust and rattle on me. Maybe somebody else can use that.

      You think I should throw that 2" cherrybomb in there to quiet down the harley mufflers?

        Might as well. Greg is still running the stock Festiva exhaust on his BPT. I'm sure it'll be all good. lol

            You will want at least a 2.25" exhaust on that B6T. Running a stock exhaust is like holding a pillow over the engine. The stock downpipe sucks

              Check out my B6T cars thread in my signature, I have pics of my 2.25" all the way no cat just muffler setup , It was cheap and easy and sounds excellent IMO.

                  I calculated 2.25" - 2.5" as being ideal.

                    I used to calculated alot too, now I just do..

                    It's really good to see you florida boys chiming in here, Since everybody is of the opinion 2 1/4 is needed I'll just do teh barest minimum to get by for now (flex pipe) and move up to a bigger exhaust in a couple weeks. I'll save the harley exhaust for the aspire. I have too many other jobs lined up for the very near future to spend time redoing all the bends, flanges, and everything.
