ANY BUYING/SELLING IN THIS FORUM WILL RESULT IN AN INSTANT BAN!

Read the rules: http://www.cb7tuner.com/vbb/showthread.php?t=43956

Myself, and the other mods have been very nice and lenient with the rules. We have been deleting threads, and giving out warnings. Some members didn't get the clue and re-posted over and over... Now ANY member buying or selling in this section will be banned... No IF's AND's or BUT's.

    Downpipe Combination

    hey guys
    I wanna do the 2.25 downpipe upgrade on my 91 cb, looking for some performance, but I dont want a loud exhaust. I went to the mufflershop and they told me that the 2.25 downpipe with a dynomax exhaust and magnaflow catalytic (for fuel economy and performance) is a good combination for $300 bucks. I though about let the stock muffler and do the other but I don't know If the difference is so notable. Or just do the pipping (no cat). What you guys think it's better? (other ideas are welcome).

    If you're looking at spending $300 for an exhaust, I'd recommend this:

    A little bit more, but well worth it.

      if you want to keep it quiet straight piping it is definitely not the way to go. My exhaust is 2.25 straight pipe and it's obnoxiously loud.

        Definitely looks good, but the shipping and installation would make it a little pricey at the end of the day. Ill check if some local store work that system and the price, but the info is good.

          Do you have the stock muffler with 2.25? If it's like that thanks for the info.

            no it's not stock. I'm not sure what kind of muffler it is though, it came with the car.

              Use a cat. Don't kill the environment for 1 horsepower... plus, it will smell bad and sound horrible.

              Any section of your piping, including your muffler, that is smaller than the rest will create a bottleneck. A major restriction.

              Get 2.25" piping, add the largest resonators you can fit. Get a good performance muffler, such as an Apexi World Sport 2 axleback (or just pick up the entire WS2 exhaust and forget about the custom piping)

                Everything on the post makes sense. But do you think the dynomax muffler isn't good enough?
