    Default Haifley hardtail exhaust help

    Hi guys, I got a 94 sportster that i'm hardtailing and I bought a pair of the lowbrow shutgun exhausts. When I went to install them the mounting bracket is about 1" from the rear engine bolts it says to install it on. So I'm wondering how bad it is if I don't have a bracket holding the exhaust on. My other option is to make some custom spacers but since its the engine mounts I didn't know how smart that was either. Thanks

    Stand back a bit and get more pics of the exhaust so the hive mind can offer solutions to use that or another bracket and perhaps place a tapped block or bung out of the way elsewhere. (No exhaust mount or anything else should interfere with easy motor R&I.)

    You need a mounting bracket and stronger is always better! You were wise to ask because intercepting the problem beats breaking studs off in the heads.

    Here's the exhaust and you can see how the bracket isn't close to the mount.

    It looks like the bracket is welded on upside down???? Or it's not the right pipe for your year........

    You do need a bracket holding on the pipe not just the one at the front...........

    Those are very nice looking pipes by the way..........

    You could make a little extension that bridges the gap. Those pipes look great on the chop. Could you get a pic of the whole bike?

    The bracket isn't welding on it's just bolted. And it's meant for a stock frame and my hardtail motor mounts don't extend past that pole so it's not flush. I was thinking about making some spacers but didn't know if it was smart to have spacers with the motor mount bolts. Here's all the photos I currently have, stole the rear taillight ideas from andrewc's build.

    The bracket need not be welded but it's mount could usefully be welded.A vertical top rail to bottom rail welded piece of bar a few inches from the aft end of the shortest pipe would be a good place for a bracket

    Round bar is sexier than flat bar and a suitable tab small enough to hide behind the pipes would support them while being unobtrusive. The further towards the end the greater the rigidity. Round bar is cheap and common at hardware stores though if your local metal supplier is handy they usually stock it cheap and may have some cutoffs from other jobs.

    If you attach it to an extended motor mount bolt, use red Loctite on that bolt. I would do that only if I had no way to weld a stronger setup closer to the rear of the pipes.

    Check pics of similar hardtails and don't feel any pressure to use included incorrect brackets on a custom. That's often not the strongest way to go and hardtails should be stoutly put together.

    Yeah I was just replying to Tattooo's comment about it being welding upside down. The pipes have a mount near the end already so I was thinking I can either modify the bracket to connect to just one mount, run it with no bracket, have a 1" spacer on the motor mounts, or weld a new tab to the oil tank to secure the pipes that.

    There's a couple of bikes that I have seen running these pipes without the bracket so I was really just asking if it's better to have a spacer on the motor mount or have no support bracket for these pipes.

    Ok is it bolted/clamped on upside down? Could that be the case?

    Common among folks who don't know better. You were wise to ask. Many a motorcycle has been fucked up by owners too lazy to support their pipes.

    BTW I always anti-seize the exhaust nuts so I don't unscrew the studs when I remove a pipe for maintenance.

    Looks like that passenger peg is bolted on a tab near the ends of the pipe...could use that tab as an anchor point for a bracket.

    2 mounting points per pipe minimum and that does not include pipe into head things (studs, bolts, clamps ect) Just my 2 cents

    Can’t totally tell from the photos of this would work, but from what I can see I would weld a mounting tab off the bottom of that oil tank and then connect it to the existing bracket on the pipes if possible. Using the passenger peg as a mounting point isn’t a bad idea either. Good luck!
