Title: Dented yosh exhaust
Post by: bbaw8 on June 30, 2009, 09:46:27 AM
Is this yosh pipe worth the $40 I'm about to spend on it? Seller claims it is useable and no function damage has been done? Also can it be fixed if needed

I think the $40 depends on how much work you're willing to do. I wouldn't pay $40 just to stick it on my bike how it is, but if you're willing to drill out the rivets, pull it apart, and try to flatten it back out, then rivet it back shut, I think it's well worth the $40.

I'm not sure what the best method would be, if you completely pulled it apart I bet you could stick a round bar through it, and roll it semi-rolling pin fashion, and take some of the bigger dents out. It's probably still going to have some marks on it either way. You would also cut it in half and throw out the dented part and just have a short exhaust, as some people seem to really like. It also looks like the front end is a bit dented where the rivets are, so it'll take a little extra effort to line it back up and seal it back shut.

It's a $350 muffler new.  I say +1 on the cutting it down shorter.  It's gonna take a bit of time and determination to make it look really good tho.  If you're not concerned with looks than it's definitely worth the cash.

I say pass.

If you're willing to do all that work getting that muffler up to snuff, then you might as well get some sheet metal, some bags of steel wool, and make your own damn exhaust can.

+1 on the diy. you can get a two brothers repack kit for $19. some sheet metal and exhaust pipe all fo rthe $40, and have a under belly exhaust with the GP style exit slash cut pipe right passed the foot.

Well, I went ahead about bought. not sure how to cut it, will lookinto that. I do like the look of the shorty cans. I may just stick the dented can on and leave it be.

Found a nice video on repacking the exhaust. Will probably do this and roll out dents in the process.

Looks just like the Busa yosh I bought from Ronin sans the BAD.

Quick side question off of that one. Does changing the length of the headers/midpipe mess anything up as far as the jets/compression/whatever else? I have a lot of interest in making the Vance&Hines on my bike a high mount if I learn how to weld this winter like I'm hoping. If there's a longer distance between the engine and the exhaust, will it do anything to it? I might also consider an underbelly, as they usually look pretty good, but that would depend on my welding abilities, as I'd have to cut the pipes before they joined, weld an adaptor on there, and then stick the exhaust on. The high mount would be nothing more than unhooking the springs and pulling the midpipe apart, getting some more metal tubes with the right bend, and welding it back together. I assume you can buy nicer pipes for exhaust systems than what they have at pepboys, the crimped bends would just make it look awful, unless I just wrapped it all in the header wrap tape when I was done.

Make sure you take pictures and post them when you get the exhaust and hack into it.

tt_four from everything I have read on the GS it is very susceptible to compression change from the pipe length. Everything I have read of Buddha and others is re jetting is a must. I suppose you could get away with it for a while but it would sound and run like a POS.

crimped pipes are also bad for flow, not just looks. do yourself a favour and get a better pipe supplier.
