So I want to know how many of you have a pipe and why you got it. Did you get a pipe for looks, performance i.e. hp gain, different sound i.e. louder, or didn't even bother. I will probably get a pipe next season for sound, I want to be heard by those mother's with SUV'S bigger than my appt! :finger: That and I do like the looks better. :D (carbon fiber just looks cool!!) However I don't think I would ever notice the hp gain that some claim. So if you have a pipe or are considering getting one, why did you get it or why would you get it?

If you only ride on the street I really feel anything more than a slip-on is a waste on time. The money you save would be better spent of rider training, protective gear, and suspension.

If you ride on the track grab the full kit.

Roberts right

I believe that the slip is perfect for the street. The increase in sound is the primary reason for the change. I plan on putting just a slip on as soon as I pick up the gixxer 1000. The benefit of the full system on some bikes is the weight savings, but I'm not gaining much so who cares right??

a pipe is for hp gain primarily...

an aftermarket pipe is less restrictive on air flow, it opens up the engine to breath like it should...thats why it sounds better too..when you get the pipe, you will notice the gain right away..even a couple of horsies are alot for a 400 lb machine..

a slip on will be fine for you..and i actually would rather have the slipon, usually a full system will give you more peak hp, but a slipon will keep the midrange torque...and the torque is fun to have, (more usable power)

it varies from bike to bike but each manufacturer will usually have spec sheets on their websites to compare power curves...find the one that gives the most bang for the buck...

also, if you get a pipe, a K&N filter is a good idea too, now that your engine can handle more air intake, give it to it...make it breath...aww yea make it run...

When I replaced the stock system with a full Hindle system on my 95 YZF, I did notice *some* difference. And then I noticed that it started backfiring. And I just wasn't too happy with it. Hubby's solution was to put in a Stage 1 jet kit. No more backfiring, and it was a bit louder. I didn't really care as long as the stock can was gone. It was really heinous looking.

I noticed a big difference in hp when I put a full system on my SV. But it too started backfiring. Worse than the YZF actually. The jet kit helped, and really smoothed out the flat spot in the lower RPMs.

Soundwise, it's loud now, just the way a V-twin should be! :D

I think I noticed more of a difference when I changed the exhaust on the SV because Suzuki sells them really "dumbed down" to begin with, as opposed to the 600 cc sportbikes.

Have you seen the stock exhaust on a 929? You could anchor a destroyer with that thing. With aftermarket it "feels" crisper and the midrange "feels" a little stronger. But honestly any time you spend money modifying your bike your mind can play funny tricks on you.

I always put a pipe on my bikes. I originally did it for sound, to be heard by the cages as you mentioned, and for looks.

Recently, I put a Vance & Hines slip-on on my ZX9 and MAN did it make a difference in the power ~I swear! Ask Sagekiller666 -he rode it before and after the pipe and I didnt say a word and he mentioned the power increase.

Also, the stock pipe MUST be full of lead cuz the weight is incredible.

I like CF cuz you can touch it while hot without tears :rolleyes:


So the reasons are:

Safety (sound)
Looks
Weight savings
Maybe clearance
Maybe power increase
and less chance of boo-boos with CF

I agree with Robert in that a slip-on is just fine for the street.

The main reason the stock pipes weigh so much is that they are built to last, out of double wall tubing. Usually you lose some power at some point in order to gain some at the top, unless you put some dyno time in. Me, I drilled my stock muffler to give me the sound with no expense, or loss of performance.

I think on this ZX9 the wight has to do with TWO Catalytic Converters (one in the mid pipe and one in the can) :mad: ... California

I put on a pipe after I wore a hole through the stock one. Makes me wonder how a company like Honda could put out such a poorly designed race rep. That stock pipe drags when yo think about going right. I guess I'm the fool that bought it.

pipe

I got a pipe because Im too old to smoke a whole joint by myself. And I got pipes for my bike to keep people from killing me in traffic. Its not a magic shield that keeps you from dying but it sure does help. After installing my Jardines Ive only been merged into once in 4 months. It used to happen every two weeks at least. I love to see poeples heads turning as I approach them in traffic. Its not an ego thing at all, it just lets me know they know Im there. LOUD PIPES SAVE LIVES.

I got a full system for the power increase and weight loss, the stock header weighs about 15 pounds, the Two Brothers header weighs 7lbs. Everything Suzuki was heavy and restrictive, so I got rid of it.

1. Weight Savings.

Stock exhaust systems weigh a ton, especially the cans. Not to mention the cans are usually high up so it is mass changing the center of gravity of the machine. The change can be felt on mots bikes right away with less effort required to make the bike change direction. The header pipes on a lot of bikes are also double wall, more so in the past than now. The double wall was to prevent discoloration which would tend to run the warranty claims up.

2. Horsepower. Changing the cans with slip ons will usually improve low end and mid range, especially when paired with a jetting change (old days) or a Powercommander II with the appropriate map. The mid jange boost is pretty dramatic and is right wher you can use it. To gain much on the top end, a full system is needed. Horsepower gains are made in the pipes, not just the can which is a muffler. Micron has made significant gains with the Serpent pipe design which significantly reduces restriction in the tight bends needed on most 4 cylinder bikes like the F4i, 929 & R1/R6 7 GSXRs.

3. Don't ever buy a pipe for noise! If you do you belong in a different club with the Cruiser guys and their straight pipes & fish tails to make noise hauling beer guts around trying at bad ass.

Thanx for the tips guys!! I have only have one more question, I like the looks of the high mount pipes and was wondering if anyone knows a pipe that can be mounted where I won't have to take the rear foot pegs off. I have only seen one picture of and F4i with a high mount pipe that went behind the foot pegs. I asked a guy at my local dealer and he said that hight mount means you have to take the foot pegs off. :( Just wondering if someone knew a certain brand or something that could be high mounted and keep the foot pegs.

High Pipe!!

There are lots of manufacturers that offer high pipes!!

M4, Two Bros, Yosh, Leo Vinci, many more, but that should get you started.


Good luck!
