Ducati Update 7a:
I’m hitting the finish line with the updates which I wanted to get done for the Superbike-Coach track day at Thunderhill West Raceway on 8/5/- so next Saturday.
First off… I am not willing to spend AT LEAST $4000 for a full exhaust system- nor about $2000 (!) for slip on mufflers (there is clearly that “Ducati” thang going on if you can follow me here). Yes I know it’s weight reduction, but A) wait and see, and B) you might wanna know what my test for a German magazine turned as we put 2 R1’s on the Assen TT Circuit to compare.
So based on my experience (which could be different than your opinion), I decided to stick with the stock headers and to ‘core’ the mufflers because they are a major bottle neck and heavy as a Smart car. Let me walk you through.
I took off the entire system to brush it clean. The exhaust flap in the Y-piece was easily removed and the hole got closed flush with a bolt. The exup servo motor becomes senseless and will be replaced with a 50 bux ESE-Eliminator so that the computer thinks… ‘all good’ :-)
At the same time I’ve removed the California EVAP canister (the smog block off plates and all the hoses and whatnot will be removed later). That’s a good number on the weight scale already, but what I could get out of those mufflers… holly crap :-)
See the pic of the open box and the stuff in there?… that got all removed (cat and db eater, etc) and nicely welded up again- finished with a mesh. Weight reduction: 1.4 kg only on the mufflers, so about 4 pounds, and a db gain of X (video is about to come).
Cost on this one… almost non. After a map flash, there will be more peek power and the sound will melt your face!!!
