Better buy some magic pixie dust to sprinkle on that Cobra-equipped bike because in the face of all information to the contrary, you want to-believe you can make that dog of an exhaust regain what performance it loses after installation. I've owned or ridden your Cobra-equipped VMax, the Kerker 4/1; a full UFO 4/1 with the UFO shorty beveled exhaust tip, with the UFO megaphone and its two different exhaust tip sizes; and the full UFO system with two different custom canisters. I've also owned different slip-ons, including the F1 2/2, the Supertrapp 2/2, and of-course, the stock VMax exhaust.
I've dynoed my bike, though not in all configurations mentioned above. I've owned one or more Vmaxes continually for twenty-five years. By a considerable margin, the dog of the lot was the stock VMax with a Cobra 4/4. It wasn't in the same league with any of the other bikes in power output, throttle response, ability to rev, or riding satisfaction. Never having ridden a Jaapanese-market VMax, which came without the VBoost, but after reading multiple stories about them, I'd say the addition of a Cobra 4/4 comes closest to approaching the Japanese market bike, with its lesser power.
I said it before, I'll say it again: nothing you can do to that Cobra 4/4 system is going to restore the power you lose from having it on your bike. No 'Stage 1' system for your carbs, no hacking-up your Cobras, fuhgeddaboutit. If you want 4/4 megaphones that make power, buy the UFO Quadzilla and a pair of earplugs, as they are ear-damaging loud.
Dozens of members have tried drilling holes in their stock exhausts in various locations: the collector boxes, and the megaphone plates, or have tried removing the megaphone plates and then drilled holes into the ends. All that does is make them louder. No extra power, just louder.
There have been members on-here with the Cobra slip-ons who have descended into the rabbit-hole in-search of the Cobra lost performance before your appearance and none of them have had success. The #1 guy who freely-offers his advice and who has built many a modified VMax, Sean Morley, has informed you that it's a useless endeavor.
I get it, you want to keep the system that came on your bike, whether it's the looks or the sound (to me, they sound like sitting on a flat rock in a wet bathing suit, and farting) or that you're $-down and want to find the magic panacea to restore the lost horsepower your beloved Cobras cost you. It's out there, next-to the Holy Grail. Don't you think that in the time since the Cobras were released, someone would have already discovered this?
It's your time to waste. By installing a stock system you can boost your horsepower by a considerable margin, and to my ear, the stock full exhaust sounds better than the Cobra anyway. Appearance versus function/performance, for most VMax riders, the latter is a higher priority. If someone gave me a Cobra system, I wouldn't install it on my own bike, I'd look for someone like you who is so-enamored of the appearance that they can overlook the gaping performance loss they cause.
I'll send you a stock VMax exhaust megaphone set, just pay shipping, so you can install a stock system, and see for yourself what you're missing in performance. They aren't pretty, but maybe after 'discovering' that unicorn of performance, you will admit that on a performance bike anything that robs you of why the bike was designed, marketed, and sold is just a poor modification. Unless form over function is your overriding goal, and the eye-candy is worth more-to you than the performance.
