Those will single exhaust post up

[sandawgk5]

I am looking at how those with single exhaust have it run. I need to run a cat also I will be running 3" from the y-pipe out the back and I am looking for a side exit behind the rear tire. I run a flip so the stock exit wont work.

It looks like I have room to fit the tail pipe between the frame and the rear leaf and run it up by the floor underneath the wheel well. The object is to get it as high as possible and out of the rocks but clear of all the moving suspension parts and stuff.

Any input and pics would be great.

I run a custom 2.5" Y-pipe into a 3" high-flow cat into a Flowmaster Super 40 (3" inlet, dual 2.5" outlet) dumping just over the axle. Here are the pictures of it:

Do they say anything at the smog station aboot dumping it under the truck? I would prefer to get it out from under the rig as down here most of where we run is dry and dusty.

I'm stuck in Smog-Nazi Cali as well, and when I took it to get smogged, they didn't really bother me about it. I dumped it because I plan to do a shackle flip on the rear to get rid of the shackle, and there's not enough room there to run pipes out.

Stock location works for me with a shackle flip , pipe above spring saves the exhaust on the rocks

I also have a exhaust shop made y-pipe , single to a bigger cat I installed , to a single muffler up close to the floor in front of the axle .

Look at my link, the last pic will show the exhaust reroute for the Flip and Inboarded Shocks.
Basically, after the Y, it goes into the Cat then into a Flow-50 then bends and routes on the outside of the frame rail. Very similar as this one

This is what I am looking at doing but I am not inboarded yet so room might be tight

ira, im not sure if i like that setup or not. wheres the end of it? does it just point down? it just looks funny to me, but it does get it up and out of the way.

Yep, I've got a 3" pipe from the Y on my '91. It's on the stock hangers to the axle. Slight upward kink at the axle (flip + 1 1/2" zeros) then continues straight backwards with only a slight kink in it running between the shackle and gas tank, straight out the back just below the bumper.
Sorry but I can't get a pic now and I'm going away tomorrow.

Mine will bend at the rear and out the side right under the rear quarter.

Here is a crude paint version of what I intend to do. It will all be mandrel bent 3" aluminized.

3" Flowmaster Cat back on my '91 'Burb

 

[muddybuddy]

see now i kinda like that, eventhough i didnt really like the last one

any particluar reason you dont just want to run the stock piping? i got all the factory tubing for my '88 from the y pipe back and it was all 3". then i just cut the end part off. got all the tubing which was pre-bent and everything for under $80.

Ya you can see my stock tailpipe dumping by the gas tank. It is not 3" it looks aboot 2.5 and aboot the only good portion of the exhaust is the y and the tailpipe the rest looks like swiss cheese. The muffler is attached to the cat by about 1 square inch of metal and non of it is mandrel bent it is all that kink bent ****. I am putting a new cat and a Flowmaster super 40 in so I figured I would change everything out to 3" mandrel bent. When I get the cash I will prolly go with a set of TES headers. I dont run inners so plug changes are not a big deal to me. I have to get the new exhaust on by mid march as I have to smog for my registration and I do not think it will pass the way it is.

Here are a couple pics of mine...If you want more detail and info, just let me know.

I have a single 3" that dumps right next to the gas tank armor. No way it will hang up on anything. I run a Flowmaster 50 SUV, and it is pretty loud inside the truck. I donno if it's the muffler, or where the exhaust is dumped, but the whole exhaust system is tucked way out of the way, so I'll deal with it for now.

I will see about getting you a pic of my exhaust when i get home tonight. Here are a few pics of my exhaust.

 

[Slapperbar]

Mine's a Big Block 70 series, Quiet inside and nice tone outside.

Yeah, I'm not gonna lie, the Super 40 is VERY loud. I have to drop down to an idle when driving past the fuzz, because the last thing I want happening is them pulling me over for a loud exhaust, then writing me up for no mud flaps while they're at it. That would ruin my day...
