AC400TX

A Few Exhaust Questions

41 posts in this topic

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

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.

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...

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. :wink:

I thought rejetting was dictated by alititude and not climate?

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

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 ass and this makes me look like a dumbass but I gonna leave it anyway. :dammit:

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