Thanks!!! I just sent it to you.
Thanks, got it! Those are Cobra 4-4 Slashcut slip-ons. I've never seem them with a coating of gold on them before! Not bad!

Since these Cobras cause a loss in HP due to the overenrichment will rejetting the carb bring the HP back up to stock numbers???
I was thinking of getting the cobras because I think they are the best looking/sounding pipes for this bike. That's just my opinion.
I'm just wondering if rejetting will bring the HP back up to stock numbers. I've heard that a 147.5 main jet is a good one to go with.

It'll help but these don't scavenge like the stockers or most if not all other A/M ones do so your numbers will never be great.
I've seen two different bikes on different dynos make 95hp with these and stock jetting. Mine with Holeshot and Morleys kit made 124hp. THAT is a lot of HP difference.

As chris noted, you will never be able to get the pipes to perform like stock or any aftermarket header. I had considered adding in a couple of joints to a set sometime back but never got around to it. If we connected the two mufflers on each side together that should help some but still not going to put any kind of decent number out.

Plus you still have the restrictive OEM headers :damn angry:

How much HP should a stock bike put down at the rear wheel? I realize that the Cobra pipes are slip-ons and use the stock header pipe but don't most exhaust systems do this as well?
Are there any other pipes out there that sound like the Cobras? I liked the UFO exhaust but it sounds VERY loud. I'm looking for something with that deep V8 rumble.

Look at around 110 and 119 hp on average, depending on the tuning.

The thing to remember is the stockers have a cross over and the Cobras do not.
Deep V8 rumble would be either the Holeshot or the Marks 4-2.
Personally I think the Kerker sounds the best.

very nice indeed....
the great thing about slip ons i would say they all go on easily....
my cobras on the old vmax were simple as hell to take off...
i can't get the supertrapps off but haven't tried to hard yet, haven't needed to...
