All other things being the same, what is louder, the Rinehart 3.5" or the Rinehart 4" slip-ons?

 

I run the 4". They are fairly loud, but I like em.
Found this for ya:

 

3.5" is definitely louder, the 4" is more low toned. very common for people to be surprised the 4" is not louder at all.

 

Thanks, I found the same. It's just hard to tell from videos.

 

Thanks for sharing. I am having HD order me the 4" Rinehart slip on with Rinehart True Duals. The 4 inch seems to be a little deeper sound than the 3 inch.

 

Yes. I agree. Pretty hard to tell.
I can't speak for the 3.5 in, but the general consensus seems to be that they are louder.

Here's a similar thread from awhile back.

I have a set of Rinehart 3 1/2" slip-ons that have about 20,000+ miles on them. I had them on my 2010 SG and then put them on my new 2014 SG back in April. They have some really cool slotted Arlen Ness tips. I never liked the plain tips on the 4" Rineharts. But anyways I don't think they are loud at all, neither does the wife. I will say they sounded better on the 98 c.i. than the 103 c.i. for some reason. I think that's because of the heaver cam in the 103 though. They are not that deep sounding but we like them ok. I was looking for some Street Canons till I found out a lot of folks have a deceleration pop with them. The Rineharts never pop or backfire at all. I'd consider a set of RC Components Slip-ons too.

 

 

I have had both the 3.5s and now have the 4 inch ones on my Limited. I only kept the 3.5s on the bike for a couple weeks. Were they louder, yes, but the sound was a raspy nasty loud. Took a trip across the mountains with them and found them to be annoying actually. sold'em here on the site and put the 4" ones on. Much much better sound. A nice low rumble and much more pleasing to the ear. If you are just lookin for loud and loud is all you care about, the 3.5s will fit that bill.

 

hmm i would have thought 4" louder
Good to know as i have considered these pipes as well
