Custom Moto GP Pipes
 

Made some new pipes today thanks to my friends at the local shop. I cut stock mufflers off, dropped a baffle from a set of Lasers in, and the shop cut some end caps. The baffle is like the far one pictured but bigger, the closest baffle pictured was too loud. I ended up drilling a few holes in the baffle once installed to improve the sound and hopefully decrease the back pressure a little. The test ride before said drilling felt good, but I think some power was restricted hence the holes. They sound great now, before the holes the sound wasn't too loud but sounded kinda funny and hard to describe. I may paint them later and possible just the tips from the weld back but that'll be another day. Enjoy!

Oh yeah, the shop only charged me $25. :D Excuse the dirt too.

Thats interesting... How is the sound?

looks loud

Cool idea! How 'bout a profile view?

Deeper now, but not throaty like cans. Before the holes it had an annoying medium pitched sound like a small loud four stroke.

I'll take one in the daylight, maybe after a bath.

I'll bet that is WICKED LOUD:eek:!!

Your neighbors are gonna hate you:D.

Cool look. Look forward to hearing them.

Hey is your avatar the pic I took @ Crabtree?

Unique look, but I'll bet it's almost as loud as an uncorked Chevy Small Block.:cool:
My 62 year old ears could not handle that.:eek:

We need a sound clip!!!

I'm with ya there! I'm also unsure of what this does for the power curve and carb mix. I do know that these are very critical for the Superhawk.

You can do a lot with local shops when you're doing these kinds of mods. I had a local shop bend and weld a mid-pipe for the VFR so I could put a hi-mount D&D where I wanted it. They charged me $70 bucks and bought them a case of beer.

My little sewing machine now sounds like a Nascar racer. Just not as loud.

OOps I'm sorry! The second picture makes it looks like that the VFR has dual exhaust. It doesn't - the Superhawk is parked closely beside the VFR and the exhaust tip shown in the backround is the right side Jardine on the Superhawk.

I did a 250 mile test ride yesterday in the mountains and the noise is about the same as a pair of TBR cans but not as deep. Nobody behind me complained, I can hear the bike but it all but fades away at speed while cruising. Power feels good, maybe slightly less on top so I may add a couple more holes.

Can we please get some sound clips on these 2 machines? I'm dyin' to hear the music! I've alway liked the sound of the viffer w/ loud pipes.

Very nice.

Here's another pic of the whole bike in its natural habitat.

The pipes really aren't that loud. Quiter than TBR's, maybe a tad louder than Jardines. I'm still wondering about the power, I think it gained a lot down low which is great on the street, but definitely thinking it lost some top end. Guess I'll drill a couple more holes.

did you have to re-jet after putting these on?
