I'm planning to put a stainless dual exhaust in my 94 full size. I have figured out the front half, with a few more measurements that part of the project is complete. Now for the mufflers back, over the rear and out the back part. Does anyone know where I might find the pipes for this ? The only pipes I can find are aluminized steel, not what I want. I'm searching for 2.5" bent pipes that travel over the rear and out the back. Made from stainless steel. Any suggestions ? I'm NOT a millionaire. Just someone who thinks this would help make the exhaust system last longer.

 

I don't think there are any stainless tailpipes besides factory, so I suggest find a shop that does mandrel bending and have them make them for you.

 

I'm not a real fan of the way they made the stock piping, front pipe small, middle pipe an odd size, and the rear different size too. Thanks for the tip about having them made. Do you, or anyone else for that matter, know if it's possible to get a diagram of a dual exhaust layout with bend dimensions for the after the muffler, over the rear, and out the back, or should I just take a wire and bend it out my self and measure it for a template ?
If I can find a company to do this prefab, I will share this info for those who don't want to keep replacing rusty pieces from under their truck. I'm thinking there are a few out there that might feel like me.

 

Just spent half my weekend, some of it in the rain, making a temporary fix to my exhaust system. The intermediate pipe needed to be replaced along with the muffler, all welded, and I did my best to save the dual pipes out the back. My work area is my parking place in front of my house on the street. This is a temporary fix like I said, lots of cutting, grinding, and I mean tight quarters. I found an aluminized dual pipe system to complete my temporary fix of the tail pipe while I search for a prefab outlet to bend my stainless duals. My question is on the aluminized dual, muffler back system. They say it will fit 88 to 95 Silverado and Sierra models, my Blazer being a Silverado, in some circles, does anyone think these pipes will adapt to my vehicle ?

 

I feel stupid, I totally missed where you said it's a fullsize. In that case, these tailpipes should fit on yours, it doesn't like your truck or year but any GM full size from 88-98 is the same from the muffler back. I suggest you start with stainless headers, shorties work great but longtubes make the most power. Then continue with a mandrel bent y-pipe, stay 3" single and use a dual outlet muffler of your choice and weld up the tails.

I found, after investigating, the only difference between the full size Blazer and the Silverado is where the gas tank is located. Where the Blazer's is happens to be where the spare is on the pickup. After talking to the company that makes the kit, the tech told me to just move the pipes forward a little and shave off the extra in the front of the pipes. Temporary fix for now until I get some estimates for bending the tails in mandrel style stainless. That will be later on since I have a few other projects to do on the little red head...

 

Yeah same with my Suburban, gastank behind the axle inbetween the frame rails. I figured since the pipes are made to go around a tire they'd fit around the tank but the tank is probably bigger. I'll have to look and see if there are a set of pipes made for the Blazer/Tahoe/Suburban, because I plan on going single 3"/dual 2.5" out.

 

I hoping to order mine in a couple weeks to finish the temp fix, and if the weather would cooperate, I want to climb under there and try to take some measurements and angle positions for a template to give the stainless benders info for an estimate on bending pipes for my true duals.

 

..Cool.. kind of planning this too.. Its kind of expensive though.. Kind of planning some new style on the dual exhaust tips too on mine.. Good luck to that mate.. I'm new here by the way.. Cheers..

 

I got my temp pipes on and like I thought they don't fit as well as I wanted. Drivers side hits the rear shock and the passenger side hits the rear shackle mount. I'm going to try to remedy this by cutting the tails and add 45 degree elbows and pull the drivers side away from the rear shock with the hangers. Welcome to the site.
