1985 GM Pickup Exhaust ?'s....

Hello all,

I have a 1985 Gmc Sierra Classic Pick up, Long bed single cab 2 wheel drive. I was wondering if any of you could guide me to some true dual exhuasts, that have Cats.. I've called Jegs, which was absolutely no help and didnt even want to help me out, to summit racing which never answers there phones on the tech section. Right now i have true duals, that are all rusted out and are coming out the stock exits on both sides. Im putting a new 350 crate motor in it, and maybe headers later on down the road when money isnt soo tight. Also could you tell me what you think about these exits if i can get them that is of course, before the rear wheel or where they are located now, just in front of the rear bumper. Any help would be greatly appreicated. Thanks a whole bunch, sincerely

Brandon

Hi Brandon..

I have an '86 3/4 ton 2by with factory duals. I don't have cats, but if you NEED to have them for emission requirements, your best bet will be a local muffler shop for the complete system. I have a big cabover camper so I have the ends out the sides behind the wheels. If you run them straight out the back, you run the risk of gassing anyone in a camper or in the back of the bed.

In front of the wheels is ok too, but you may end up with dirty wheels! LOL

i had a true dual set up before the rear axle..... it would be a bit louder.. but also a bit cheaper to make.. as for cats i would check with your local emissions shop.. cats arnt cheap.. and i wouldn't put them in unless i had to.. out here 86 and older don't need cats.. just a thought.. expecialy if your on a tight budget..

You can get small aftermarket cats at most parts stores now for under $100. Put 1 on each side and run real duals.

Adding Headers to that crate motor will eliminate worrying about the lack of Mandrel downpipes from the manifolds.

Quality hi flow cats for a lot less than prices above.
Drop me an e-mail if interested.

dual exhaust

I have an 85' chevy full size blazer and I just put a 2.25 inch dual with H-pipe out behind the rear tires. I didnt use any cats because they are too expensive and we dont have emissions tests her in N.M. But if you are going to use cats go with the 2.5 or 2.25 inch catco high flo cats, they cost about $55 a piece. I used dynomax super turbo mufflers and they sound real nice, not too loud, and a big performance increase.

Oh yeah, if your truck didnt come with dual cats to begin with, you will still be illegal by installing 2 cats. Becuase it is illegal to even change the stock route of the exhuast, so if you dont have emissions laws dont do the cats. JC Whitney sells some dual kits for I think 139.99 out before rear tires dual 2.25inch w/out cats.
