Question Questions about baffles...

So, I've been lurking here for a while now and I done a few things to my 94 since I got it a few months ago. My question is about baffles... Attached I have a picture of my bike with the "modified" (not really) exhaust. When I got the bike the first think I did was go though it with my brother and fix all the little things (we are currently doing the stator mod, its going well). We discovered that the PO has cut out the baffles in the stock muffler and had cut the muffler ends from the pipe instead of just unclipping it. We decided to just take off both mufflers, put on exhaust tips and clip the chrome back on.

Long story short, looks great, way too loud. I need to quite it down but I'm concerned with putting baffles in these already rigged exhaust. So, my questions are:

Will keeping my pipes short hurt my valves or over all engine?

Will putting baffles into these pipes as they are fix my loudness issue with doing further harm? aka: "V-Twin Manufacturing 1-3/4″ Baffle Set for Drag Pipes" from jpcycles

Or, should I just weld the stock mufflers back together and then put them back on the bike with some kind of baffle to replace the one the PO tore out? And finally, if so how would I go about doing this?

Thanks to all you guys, Snipe.

Is the Goat's Belly (power chamber) still under the bike connecting the 2 exhausts?

If those are just straight pipes and no baffles, you are lacking the back pressure the engine wants to run well. If the bike is running lean, you could do damage to the valves.

throw some Harley Dyna mufflers on it.

If you really want stock muffs, I am sure someone has a pair they took off.

The goats belly is still there, I would rather leave them as they are and just bolt in some baffles. I'm pretty cheep and just want the bike and run/look decent without breaking the bank.

Dyna mufflers are Cheerio on Ebay, you can score a pair for around 40 with shipping. Check the for sale section too.

So just adding baffles to the pipes I have left is a bad idea?

If you still have pipe installed after the goats belly, it should be fine with baffles. You wouldn't be able to put the baffles directly (without altering the belly) into the belly since the holes aren't straight through.

I think if someone really wanted to, baffles could be used in the downpipes alone without any bad effect other than it sounding pretty choppy.

I think I have about 8'' of straight pipe at the very end, I was hoping I could just put a universal 8" pipe baffle inside that like the one mentioned above. But now you guys have me think that a fatboy/dyna muffler is really the best overall option. Anyone have good suggestions on these HD mufflers, fit, year, mounting?

Sorry if I'm asking too many questions, I just want to understand it fully. Thanks.

The newer ones have catalytic converters built into the mufflers. They're also typically a bit on the long side. I've seen a number of posts on here about putting on baffled sportster mufflers. They can be found pretty cheap. I put screamin eagles on mine and I'm pretty happy with them.

I looked yesterday and saw one set of HD Dyna mufflers on Ebay, starting at $19.95. Several others were listed but are much higher priced.

On another site I use, they have a pair of 32" HD fishtails at $30 and a pair of 22" HD Dyna mufflers at $19.95. Both sets looked really good in the pics.
