I know it has been discussed on here in a previous thread (I have read it, it is what got me going in this direction)...Soundbites have been included and such, but what I am looking for is a little bit of specifics on sizes... I am going to build an exhaust this winter using a glasspack. What size should I use?? What size inlet pipe?? Can (hole..bore?)?? Length (I am thinking 12" or 14"...isn't it the shorter it is, the louder it is?) ?? I talked to the guy that does all of my exhaust (good guy) he said that we could weld on a 3" mandrel bent tip (for looks)...showed me an example (tip was slipped on to the glasspack itself)...said it would look like there was a big ol' pipe coming off of it...I liked it. This is for an '02 S3T...I want it to be louder, without spending a whole lot of $$$$. Figure if I can get one together for under $50 then I can use it when I want (most of the time) and run the V&H the other time. Thanks. | ||

have you felt how heavy a glasspack is? | ||
| Essthreetee |
Nope. | ||

My only glasspack advice is to get one with a perforated core, not a slash cut one. The louvered, slash cut cores are pretty restrictive. A V&H is essentially a glasspack with a perforated core, so I'm not sure exactly what you'll be gaining if you've already got one. | ||

I don't know...wasn't really trying to gain anything other than noise, but at the same time I don't want to LOSE anything either. Figured that if I could make it louder, look fairly decent, and not cost too much in the process then why not...bored mostly.  | ||

essthreetee- V&H make a couple of different perforated tubes / cores / baffles. I think one is called "Race" or some such. Probably get you quite a bit more bark - and maybe even some more bite. That may be the easiest route... Call 'em up and find out about parts for the SS2-R muffler. It's nearly universal in V&H sport applications with minor inlet & exhaust differences. -Saro | ||

Saro...thanks for the info. I will definitely be giving them a call.... | ||

I have heard V&H pipes that have been hallowed out and sound just as loud as a force pipe. You may want to see if you can pick one up off ebay and then it would be an easy swap with your current pipe. I run a WileyCo and will be building a straight pipe swap piece this winter. | ||
| Essthreetee |
Koz - If I can swap the baffles with little effort, could I also just pull them out?? Is that what you are meaning?? Because then it WOULD just be a straight pipe...right?? But I would lose a lot of performance by running with NO back pressure...wouldn't I??? | ||

Do NOT run a V&H without packing and without the core. It is NOT a nice pipe. Without Packing and WITH a core, the core will self destruct! It relies on the packing for physical support. Completely gutted (just end caps & the shell) mine sounded metallic and didn't really make good power. Just my experience... -Saro | ||

You are going to loose performance reguardless with what pipe you change too. I have a guy in town I have ridden with that ran the V&H pipe with basicly nothing but the can. He removed the rivets on the tailend of it and took out the guts. It was loud and had a rumble/echo type sound. You could just try starting your bike next time you repack your can like this and see what you think. As far as back pressure goes. My dad has a 1200 sporty with X-1 cams and Buell thunderstorm heads. With Screaming eagle cans he had 78 hp, with very open V&H pipes he had 72 hp with a small dip in power just below 3000 rpm. His bike is louder then my M2 and that is more important to him. | ||

have you felt how heavy a glasspack is? Betcha it weighs the same, OR LESS than my D&D.. Its cool though, looking to go a force... Chase} | ||

The packing in the muffler serves a couple of different puposes. On the V-twins like the Buell's, the exhaust pulses are LARGE! The packing not only quiets them down, it dampens the shock waves. Without the packing, the mufflers self destruct from the pounding. Find someone that runs with no packing in a V&H, check out the rivets, I'll bet they are loose. Back pressure is also not a totally accurate term. A pipe like a Boss or a V&H are essentially straight through with no baffling. It's the pressure waves generated from the exhaust pulses that move back and forth along the length of the entire exhaust system that cause the gains or losses in performance. Changing length of the header runners, the collector length or the muffler length will have different effects on different parts of the power band. Diamater changes will do the same thing. Changing the "reflectivity" of the muffler internals will also changes things. A loose packing acts different than a tight pack as will the material used for the packing. Kind of a black art really.

I have personally built a slipon glasspack muffler and ran it for 2 years on my 99 m2. It was loud but not as loud as the force pipe i run now. I used a 2.5 inch inlet and 2.5 inch outlet muffler with a turn out (witch made it louder). the muffler was a hearthrob from jc whitney 12 inches long part# wl222840 $24.99, then I used a dynomax muffler 12 inch long I cant find the part #. I liked the dynomax better.. | ||

or you can go to summit or jegs and order the pipe inserts. Basically they are the muffler insided either 1,2,or 3 slips. I'd guess that muffler packing could make it quiter. The glass packs I've delt with wiegh much more than a nice alum muffler | ||

You are going to loose performance reguardless with what pipe you change too That is an inaccurate statement... A poorly designed pipe, header or modifying your exhaust without knowing what you are doing will result in poor performance. I run basically a straight pipe designed by KT components and from that to a stock header with a Supertrapp was a difference of 10RWHP Are you going to build a full exhaust or just a slip on??} | ||
| Essthreetee |
Are you going to build a full exhaust or just a slip on??} I was just going to be building a slip on...and yes I DON'T know what I am doing. I do know that I am NOT going to be racing...so if I lose a little (as little as possible) HP, then no biggie. Plus if I don't like it....back on goes the V&H and I am out a few $$$. The glass packs I've delt with wiegh much more than a nice alum muffler It couldn't be as heavy as the stock ton that I took off in place of the V&H...so I figure its gotta be ok...  But then again, what do I know. | ||
| Spiderman |
Why don't you modify your stock can. I have seen a lot of success with that. | ||

I was just going to be building a slip on...and yes I DON'T know what I am doing. Yeah, that is where I stand when it comes to actually designing the exhaust. I figure without the use of a dyno, it would not be easy to make a pipe that wouldn't loose some power. On the other hand, Once I put my bike together (WileyCo pipe and force intake) I took it to Appleton HD who after Dyno tuning and rejetting the carb got me from 67 hp up to 78 hp for $165. It was worth the money to let someone, with the tools and the talent, dial the bike in. | ||

If you go with the homebuilt setup, stay away from a glasspack as these will eventually lose their packing just like a v&h / wileyco / etc. For a maintenance free setup, use a Moroso spiral flow racing muffler. Davefl has one of these on his - see the pics..... http://www.badweatherbikers.com/buell/messages/43/44564.html http://www.moroso.com/catalog/categorydisplay.asp?catcode=35001 http://store.summitracing.com/default.asp?target=partdetail.asp&part=MOR-94050&N =400105+4294923429&autoview=sku | ||

Essthreetee, I think this should answer your questions http://www.badweatherbikers.com/cgibin/discus/show.cgi?tpc=47623&post=494409#POS T494409  | ||

You guys haven't figured it out yet, huh? I had a cherry bomb glass pack on my S2 before there were anything known as "aftermarket" pipes. It's simple. Run the pipe in the opposite direction! |
