Anyone know if any changes need to be made after taking the stock tip of my bike and replacing it with a PMB endcap? will my bike run any differently?
seems like the opening is bigger than what was oem.

any suggestions or comments very appreciated!:thumbsup:

anyone going to gorman for christmas weekend? predictions for crowdedness?

Just an edit:
this thing was so easy to put on. the instructions supplied with the product were extremely straight forward and with no tools it cost me:
1. cordless drill : borrowed Free! :smirk:
2. high temp silicone : 6.99
3. thread locker for the allen bolts : 3.20
4. rivet gun from harbor freight :4.28

totaling :smirk: 14.47

I don't have an '07, but I do have a PMB end cap and it went right on, no worries, nothing to change, ran the same.

I threaded the holes in the end cap so I can remove/repack easier.

Hope that helps.

Don't you need a green sticker to do Gorman? Used to back when I was riding there.

I put a pmb endcap on my 426 and it looks great, slipped right in with no mods, and has the option of running a quiet insert for the places that are finicky about sound. Truly a great product.

the sound was just as loud as stock, but when I run my quiet insert at strict parks, I have ran a 90 db sound test

they are expensive, but are less expensive than a new louder pipe. Especially for those who like the power that their bike has stock but just want to add bling and a spark arrestor

No, adding the PMB end cap does not reduce (nor increase) the sound level of your bike. At least I couldn't tell. Never had a sound check when I lived in Kalifornistan. And I don't believe any other state mandates them.

I do have the sound reducing insert, though never used it. It just rolls around in the bottom of my tool box. I use it for a paperweight.

I swear mine got a touch louder when I put it on.

The PMB has a slightly larger oulet compared to the stock end cap.

Maybe it just changed the tone slightly?

Maybe its all in my head?
