They sound awsome but the neighbors hate loud pipes. I actaully like the R4. I don't think that a quiet core can help an HMF slip-on that much. I buy most of my stuff on Ebay. I heard HMF pipes are around 104db's.

 

My hmf actually isn't that loud. Maybe 97 db's!!

 

How much is it to get new packing for the E-series pipe? I would still like to know my original questions because they were never answered.

Tractorpacker, I seen a new White Bros. S-bend E-series at the dealership and the canister shorter than mine and it had the new white brothers logo on it. More than likely the cracking problem should be solved now.

 

well i have had a e-series full set up for a year and a half and had no problems. I do have a big dent in it from where a gut hit me going thru the trails but all welds are good no cracks but the reason they crack is simple two different metals stainless steel and aluminium got to be a weak point but i do love mine got a big increase in power and wheelie ability. I whould recomend it definitly

 

Does anyone know how much packing is for it? Also is anyone running a Quiet Core? I have pics in my page of my E-series if you want to see it.

 

Just got back from the dealership and I wanted to order the clamp and spacer but the place they called was out of stock and said it would be a month before they could get one to me. I didn't order one. Does anybody know or have an idea of where I could get the spacer and clamp at? Also, would any other aftermarket clamp work? The stock one is too large in diameter to fit the White Brothers silencer.
