Hello everyone. Today I sawed off my factory exhaust and went to install the muzzy. I confused as to which pipe goes into the main exhaust ports.

any help is appreciated thanks!

I had the same problem. So I decided to find the two pipes that fit into the mufflers. This leaves only two pipes left. You should be able to figure out how to connect the two left over pipes to the muffler pipes. Then it's simply the other end of the left over pipes that go to the motor. I hope this helps.

ok yea good idea. Im gonna install the mufflers and the brackets and all that then work my way backwards. also, when fastening the head pipes to the exhaust ports all you use is the oval shaped bracket that gets bolted down right?

thank you for the input!

Drivers side pipe: long head pipe and short exhaust pipe with O2 bung in it.
Passenger side pipe: Short head pipe with long exhaust pipe, no bung.
Both pipes will be angled to the drivers side past the drive line if that makes any sense.

I would recommend installing new exhaust donuts when you do it and leave everything loose until you think you have it. Make sure you have the spacing Muzzy recommends off the rear or you don't have it on right. My cans slide a little past the exhaust pipe flange to get the clearance and no problems yet. Love the Muzzy.

This photo was taken from the drivers side wheel well. Sorry for the mud, but notice the O2 bung and drive line and spring locations. Hope this helps.

Yes, thank you!

 

[Rhurricane200]

what do you mean by new exhaust donuts?

 

[Fozzy]

Their little gaskets that go in the head and get smashed down when you tighten the flange bolts. If you have not seen them, they are still in the head. New ones are not a must but will help guarantee no leaks.

Oh right, I understand now. Thanks alot Fozzy, you have helped me tremendously! Installation is a breeze now haha.

Your instructions are a million times more help full than muzzy's

today i had to grind off part of the driver side arch protector that goes over the rear diff because my driver side muffler would not fit between with only the top muffler mounts installed. Do you know about this? Also, how in the heck to i get the allen bolts in for the bottom muffler bracket closest to the exhaust ports? there is literately no room in there..and its not a matter of the bed being off, more so the top of the rear diff and just tight space. Any ideas is appreciated.

Thanks!

that was a PIA for me as well. Use an allen and take your time. I had little to no room for this. It will work. It just take your time.

 

[Rhurricane200]

Man you arent kidding its a PIA. I was thinking about removing the mufflers and the top bracket closest to the exhaust ports so that I could thread the allen bolts for the bottom bracket into the top one and then bolt both top and bottom brackets back onto the frame. Hopefully this will work because whats hard for me is getting that allen bolt to thread in just a little bit...

 

[tazz3069]

I feel you. Had the exact same issue. You did remove the metal shield right?

 

[Fozzy]

Yes you have to turn it 1/4 at a time. I found the muzzy directions to work the best. I thread locked the top brackets on and just started the front and rear bottom brackets and wrapped typing paper around the cans and slid them in. I didn't have the heat shield on.

Yea, I did remove the metal shield. Ok thanks guys I will give that a whirl now this morning.

Thanks again for all your help.

Today I finish the muzzy and begin a cam and machine sheave install!

 

[Fozzy]

Good luck, cam not to bad, just make sure the decompression pin is in right and the sheave you will need a good air gun to get the bolt off. Tune your fuel injection and you will be amazed how much it wakes the rhino up.

yea im looking forward to see the gains...as for this damn muzzy, I really gotta hand it to them for a difficult install. Im sure their engineers could of done a better job designing the mounting brackets...the rear one at least. They get an F+ so far and they only way they'll make it up is if im completely blown away by their 800 dollar exhaust system!!!

please excuse my frustration!

I didn't see any mention of you having a fuel controller. If you need help with the mapping for your mods, call Nate over at Alba Racing and he will set you up. Just Muzzy and a stage 2 Rhino Hot Cam increased the horse power to 40 on my 08'. You will notice it big time! HAHAHA!!!!

 

[Rhurricane200]

Thanks Roo...I do have an MSD with the correct mapping loaded. I finished my Muzzy install yesterday and today I begin my machine sheave and cam install.

Thanks again everyone!

No problem, another thing I will mention is that if you have the spark arrester screens installed in the muffler cans, keep an eye on them and don't let them clog up with exhaust packing. This has happened in the past with Muzzys and caused damage by causing a very rich mixture, actually washing the oil from the cylinder wall, damaging the piston.
