Videos are both very fun and useful. A ride video is on my list of things to do in the spring too..
If MAC made 1 1/2" headpipes, I would be tempted to get their TT style 2-2, with the pipes tucked in under the engine. Mainly for the looks, and I think I could live without the center stand.
Lots of information to unpack here. I think I will go with the mike headers, now on to figure out which muffler...
Since we're on the topic of exhausts, is there anything great about having a 2 into 1? Is there a performance gain?
Performance gain? Not where it counts. You won't see a 2-1 system on an XS650 race bike. On every 2-1 system I've seen, the second bend of a headpipe will find the asphalt in even moderately frisky cornering.
I've got an old 2 into 1 on mine that wouldn't ground out as it runs down the center of the bike and comes out fairly high just in front of the back wheel, not sure why they seem to make them so you can't go around corners now
I guess it has to do with retaining the center stand.....Cool bodywork BTW, Tracy?
WOW Jay, a Tracy faring...very rare and looks great on your 650.
Stock 79 Special mufflers tuck in nicely. The fit is clean looking. Although I have not yet heard these, I think it is fortunate to have an original exhaust system in good condition. I am curious as to why so many XS owners have replaced them ? Is it because of a desire for better ? Is it because the originals were worn out ?
Because they're usually shot. They're either rusty to the point of having holes in them, or all dented and scraped up, or all of the above, lol. Besides, replacing a stock system can usually net performance gains if done right. The early stock systems aren't so bad but the later ones are more restrictive (once the E.P.A. stuck their nose into things).
My bike had a crappy aftermarket exhaust when I bought it. I hated the sound and look of those mufflers so it was an easy decision.
Yes it's a Tracy body, ive had a couple this ones a muck nicer shape
For me that is one of the biggest problems with old bikes, finding them with even usable exhausts. I've been lucky to find a couple bikes in close to runable condition for around $100.00 and being a tight wadded cheap skate just hate to spend three times the cost of the bike on an exhaust system!
Yes, to find original 77-79 Standard mufflers in primo condition on a bike for sale locally is always a goal. For several years I have intended to find that, Buy the bike, Remove and stash the exhaust system and sell the bike. Sadly that nice original exhaust system just does not show up locally in any of the ways I search out bikes for sale.
Unfortunately, shelling out for a complete new exhaust is just something many (if not most) of these bikes need. But we should consider ourselves lucky. The few hundred dollars we have to spend is far below what many must spend on other bikes.
Has anyone tried these. If so how loud are they?
This seller has a shed packed with new HD take off mufflers. I bought two for a Goldwing I fixed up for $10 each.
I have the MikesXS 1 1/2" pipes, purchased fro Heiden Tuning. To be honest, I am not that happy with them. Both bends are too sharp (bend radius too small) in my opinion. Just don't look right.
Hoos and Mac only offer 1 3/4" pipes, as far as I can tell. Not ideal for a street XS.
What we all should do, as a group, is to approach Hoos, and suggest they make a 1 1/2" street headpipe option, with nice large bends, and a slight upkick at the end, suitable for straight mufflers. I am pretty sure that would be a popular item.
Speaking of bends, Comparing the Standard look to the Special look.
That nice tight Standard bend looks very appropriate for a bank of four head pipes in a row all being tucked in to save space.
On these twins which have more character and free space I prefer the more flowing bend look of the Special head pipe.
It would be interesting to know if either shape is superior to exhaust flow over the other but I would bet on the Special for performance as well.
I'd pay quite a bit for 1 1/2" single wall/ thin wall SS headers with the "Special" bend......
Sent hoos a PM.
