A Few Exhaust Questions

[AC400TX]

I'm thinking about a new muffler for my AC 400, but I have a few questions...

1. Will it void my warranty?

2. Will I get a noticeable gain (torque, speed, etc)?

3. Will the pipe require me to re-jet or do anything else?

My choices are:

Muzzys

Super Trapp Mudslinger

Super Trapp IDSX

[trailblazer_02]

yes

yes

yes

i dont have a pipe for my quad but yea it will void ur warranty... idk if it will give u torque but i do know it will give u hp... ive never heard about rejetting ur quad,, but i dont think u have to anything else to ur quad

[01 RAPPY 660]

u will have to re jet up in size on your main, and yea u will get more torque and speed.

You DO NOT have to rejet in every situation. I put an after-market pipe on my quad and did not change my jets. It runs fine. Only difference other than the performance gains was every now and then I get a little back fire. Like once a ride. If you put a pipe on and it is popping like crazy change it. You will know right away if you need to.

i would rejet anyway so u get a little more power from your wheeler

[outlander560]

u could rejet but u have to know wat u r doing... i agree with bot i dont see the need to rejet it really doesnt give u that much of a power boost..

well im one that (LOVES) the power and speed so, i would rejet if needed to even if it's just a small power gain it ALL adds up.

[outlander560]

yea ur right it does add up,,, but he doesnt need it to put on an exhaust

[01 RAPPY 660]

well lets hope he likes his new pipe:yes:

[SunLrider]

hope you like the new pipe:yes:

[outlander560]

so r u going to get a pipe or r u going to wait for the warranty to be over?

[Naterenfo]

okay i have a question, What is re-jetting? and how do I do it?

[outlander560]

rejetting is wen u take the jet that is inside ur carb and change it to a smaller jet stream or a bigger one.... now u do get better mpg and more hp..... but a problem with rejetting is that if u live in a region with different climates you have to change the jet for warm weather and cold weather.... it is a lot cheaper then the other kinda of mods out there but u also need to know wat ur getting urself into before u tear ur carb apart...

[AC400TX]

so r u going to get a pipe or r u going to wait for the warranty to be over?

I haven't decided yet. I just bought a winch and a wheel and tire kit, so it'll probably be a little while before I get anything else.

I'm trying to pace myself.

[outlander560]

that is a good idea... did u take it out yet

[Stoopidbot1]

Re-jetting is dialing in your carb.

[mywifeknowseverythin]

You cannot REJET a Carb on the internet.....

But....For any of you that have Questions......I found this for you.....Very Good Read

carb tuning

Personally,,,,,,When I change a Pipe.....From Stock to Aftermarket,,,OR,,,,Aftermarket to Aftermarket.....I do a Plug Chop to see where Im at....I let the Plug do all the talkin:wink:

i dont even like to touch my carb

I thought rejetting was dictated by alititude and not climate?

Basing it on seasonal changes would be a major design flaw....IMNSHO......

makes sense

[Sc0tt]

Rejetting is necessary when there is a change in the air to fuel mixture. It can be with altitude or it can be with changing parts like intake and exhaust components. Now that I have this written I think that txduggan was being a smart as* and this makes me look like a dumbass but I gonna leave it anyway. :dammit:

[SunLrider]

ive always wanted to put a banshee carb on my sunl just to see what would happen:wink:

[outlander560]

i know that it is about altitude,,,,, but wen i called my dealer after installing the kit he said u have to change it to the different climates.... sounded a little odd but i have no idea if he is right or not...

it depends on how thick the air is, like in the winter u drop a size becuase of the air in winter is thiner.

[SunLrider]

whoa i never though of that

[01 RAPPY 660]

okay i have a question, What is re-jetting? and how do I do it?

theres 2 jets the MAIN & PILET. the pilet jet is for bottom end power changes and is fine tuned with the air fuel screw, the main jet is for mid and top end power changes a mid power change is done by the needle clip setting and a jetting change, and the top end power change is done with a main jet change and needle if needed. If u are running lean(to much air per gas) then jet up, and if u are running rich(to much gas per air) then jet down.

i hope this helps you.

mine was running too lean the other day i think it was from hitting a tree, it shook it up

LOL.............. what did that tree ever do to you?

That's on a 2 stroke. On a 4 stroke there is only one to change for altitude.
