2.25 are as high as Rush go and are the loudest. Not recommended without high flow and download. I have 2.0 and they are pretty loud, but good loud. I have heard 1.75 too and they sound good. All depends on the person.

Bigger baffles are for more "built" motors. I wouldn't recommend getting bigger ones for your mod's.

You can just replace the filter with a high-flow filter like a K&N and not pay for the entire housing. Most people replace the whole housing for a different look though. I just installed V&H with quiet baffles on my bike and I'm loving the sound.

more dumb questions....

When I take off the old muffler....do I have to add any lubricant or sealer where it slips on the exhaust....or just tighten up the clamp...

also...do I havee to put the stock heat shields on the mufflers.....

thanks guys....sorry for all the dumb questions....but now I want to start working on my bike....my dealer wants 108 an hr......

no lube or sealant is needed. the stock heat shields fit right on the rush mufflers perfectly and will hide any blueing. Do yourself a favor and go with the 2"baffles they sound great and with the h.d download it will really wake your bike up.

when you say the HD download....do I have to change the mapping that came with the bike....or just leave it alone?

Thanks

That is what the download is. It runs about $150 at most dealers.

you can just leave it alone if you want but the download will raise your rev. limit and whatever else it changes seems to be sort of a mystery, but what wasnt a mystery was the differance it made in my scoot, like when getting on the interstate. it is a noticable power increase. Im not saying that its as good as a power commander-sest-etc. but it does make a noticeable differance. if you only want sound and sound alone put the mufflers on and go riding.

thanks....but again conflicting reports...I was told if you just add on the mufflers...you do not have to do anything else with the bike.....

if I am going to have to pay $150 for another download...I might as well go with a PC V
