    Opened up cobra 4-4s for Sale. Loud.

    Came on the bike. I opened them up by cutting off the battle ends. Will take best offer and would be happy to ship in the CO-US. Just installed a stock muffler so figured I would sell or trade these off to someone!

    Cut out cobra baffles.

    So from the inlet side took my long pry bar and busted out the center cap (small plug inside the baffle tube) and used dremel to cut the spot welds and a 1-3/4" metal cutting hole saw and cut off the baffle end plate. The results as far as I can tell I picked up some midrange power compared to...

    Strange Cobra Phenomenon

    I purchased my V-Max here in Hungary a couple years ago with a custom VERY LOUD exhaust system. I have since purchased a Cobra 4-into-4 system for a quieter daily ride to work. In a different post, I've had a chronic problem with #3 cylinder popping and sputtering. I recently returned from last...

    Needing a good used cobra slashtip

    Does anyone happen to have decent take offs of the Cobra Slashtip muffler for sale, especially the lower left unit, with good chrome? I think I have blown out the packing or whatever is inside, as it sounds like a straight pipe on the one muffler. Thanks, danlankford@hotmail.com

    Cobra 4 into 4 Slip-ons

    When I bought my Max a year ago, it came with the Cobra 4 into 4 slash-cut mufflers. Far and away the best look IMHO for the classic musclebike look. However, the allure of the dark-side called from the bark of the Kerker 4 into 1, and the Cobras were retired to sit alone on a shelf. I planned...

    Cobra Slip ons w/stage 7 kit

    Looking at buying an 85 vmax, the owner put a stage 7 kit in the max without changing the exhaust. it idles fine but you must choke it to drive. The price is right. do you think it just needs an exhaust system? Would it work run with cobra slip-on's I have?

    Cobra Exhaust back to Stock

    I just got my first Vmax 2003. The past owner changed the Stock exhaust to a cobra 4-4 Set up. I have read poor things about the set up and loss of horse power and am looking at changing back to the stock system that was supplied with the bike. The past owner put different jets in the carbs...

    Looking at my Cobra Slash Cut mufflers, it looks like the baffles are just welded in from the outlet end. Single weld, as seen in this image It would be nice if they could be removed. Is it just this one weld per muffler that holds the baffle inside the can? I would very much like to be...
