? For exhaust guru's


A key point here, ride thousands of miles in real world conditions
 
Paul, Art definitely does not live in the real world, so how in the world did Carpenter Racing come up with the most efficient design?

I suspect that there's some black magic at play here.

Don't ask me how I found this, but at 5:20 into this macabre video, Art can be seen employing his test protocols (scary stuff)...

 


Phil, we're taking your mushrooms NOW! Go vomit like a good boy, then turn it back on Dinah Moe Humm!!!

WELL PHIL you are witness to the Road testing and also the drag strip testing at ATCO DRAGWAY and lots of Dyno time testing different designs
 

How on earth can your butt-dyno street rides of over "thousands of miles" assess the performance of an exhaust system???
 
Raaaaalph

'Tis true that Bob Carpenter and his friendly elf, IFT test the ever loving life outta' all the mods which spring forth from Carpenter Racing well before they are released to the general public. and Art's a pretty good sport re: all the abuse he's earned here.

Now back to our regularly scheduled 'shroomfest


 
Oh, you mad alright.. What's next, one of these?


or, for a bit of winter fun, one of these...

Well that's what I do and have been doing for 45+ years of riding, I have learnt a thing or two about what does, and does not work.
Not sure if this one does tho'
