Hi Burt I didn't weigh the muzzy but it not heavy. I would say that the stock header tubes weigh as much if not more then the full muzzy. I've had good luck with muzzy. I had a Full ti muzzy on my 2000 Zx-12 I paid like $700 for new.lol
Had one on my 06 Zx-14.
I'm not knocking Brocks at all I'm sure they make a great exhaust BUT.. $1800 man that is a lot of money. I paid about $1100 for everything (full pipe,Pcv,fans,block off plates)I'm saving for BST also.
As far as the difference in power. I was told the pcv would come with the right map. Boy was I wrong. It had the stock map in it. This is the e-mail I sent Dave @ muzzy. It happened Sunday I still haven't slept.
"Hi Dave this is Jody from WV talked too you last week about the fan blades. Here are a couple of pics. It looks good sounds great. Runs like crap. How bad you ask? Picture this if you will.
2005 zx-10 with just a yosh slip on with that cheap Chinese plastic from eBay and 2 PEOPLE on the bike. From a 2nd gear roll when I hit 3rd he went by me like I was hard on the brakes. It was that bad. It was sooo bad I’m thinking of painting my bike a different color changing my name and moving too a different state. Think god it wasn’t a Suzuki"
With that said. Dave sent me a map today. I haven't rode the bike as of yet.
The map he sent me i thought the Fuel table numbers would be bigger. I figured bigger motor & more air bigger numbers. I found my 06 map he sent me it has way bigger fuel table #‘s
I’m going too get a dyno tune. Talked too them Saturday he said they are 7 days behind.
I haven't felt this bad since the bully in grade school used too beat me up and take my lunch money
Back when muzzy made real exhaust
