    Question about \"off the shelf\"dual exhaust.

    Do "off the shelf" dual exhausts run below the tranny skid plate or above it along the frame? I want to find one that goes above the skid plate so you cant see the pipes from the side. Thanks

    Re: Question about \"off the shelf\"dual exhaust.

    Most I've seen run above the skidplate/crossmember, but never really fit right - Most muffler shops will run you a complete dual exhaust for well under $200, and route it just about any way you want.

    If it weren't for bad luck, I'd have no luck at all[​IMG]

    Re: Question about "off the shelf"dual exhaust.

    The shops around here will only work on the exhaust from the place where the cat used to be back. I want to get some pipes to that point from the stock manifolds and let them do the rest. Right now I have pipes running below the skid plate and I dont like how it looks.

    Where ya located? You need to get that profile filled out!! Another option would be to put a set of headers on it and run from there.

    I would still need to get some pipes from the headers to the place where the cat used to be. How hard are headers to put on? I have a 91 Blazer 4x4

    Re: Question about \"off the shelf\"dual exhaust.

    I did my headers in about an hour and a half on my 85. Once you've gone that far past emissions correctness, the shops will typically give up on the converter issue. You'll have to put your oxygen sensor in the right hand collecter, other than that, it's a quick bolt on affair.

    Re: Question about \"off the shelf\"dual exhaust.

    My dual exhaust runs over the crossmember and fits PERFECTLY. It's a Dynomax header dual kit. Well worth the $100. They also have a manifold kit that I've also installed on another truck. That fit good as well and costs $110 or so. Try Jeg's High Performance. Just add two mufflers and 4 clamps, other than that it's complete. For a K5 you won't even have to cut any of the pipes to shorten them. You just bolt it right on. Took me less than 1 hour.

    Re: Question about \"off the shelf\"dual exhaust.

    Headers will work fine, but you need to make sure you have an O2 sensor bung welded in on the LEFT side. Most places you can get headers can put the bung in for you. Not all exhaust places will work on a post '75 vehicle if you want true dual. I found a place here in Wichita that did mine. He's all about true dual. He told me he wouldn't do anything but that on my truck. I laughed and thought that was cool. I'm going to get headers for my '88. Most exhaust systems run over the crossmember. I haven't seen one that goes below it. That's new to me.

    Sorry about the backasswards O2 sensor - Having a Ford moment there.

    You scared me for a second there! I had just gotten through welding the O2 sensor bung on the left side!

    I would get shop to bend the pipes for you. I installed a dual exhaust kit and it sucks a big one

    Re: Question about \"off the shelf\"dual exhaust.

    If you get a long bendable rod or coat hanger and then crawl under your blazer and make the bends how you want the exhaust to go, most exhaust shops will bend you the tubing and then you can install it your self.

    Re: Question about \"off the shelf\"dual exhaust.

    How about the 82-up(?) 6.2 litre diesel exhaust? True duals, factory hangars (read, never loosen up or rattle) and will bolt right up to 350 exhaust manifolds. Probably real expensive to buy it all from GM, but worth a shot. If you can buy them aftermarket would work as well. If you are too lazy to surf my site (just kidding) to see the exhaust, heres the url to my pics that show parts of that setup: http://www.dorianyeager.com/index2.html

    Re: Question about \"off the shelf\"dual exhaust.

    My local exhaust shop wanted to bang me $280 for dual cat-back, so I went elsewhere. That place wanted to charge me $250 for a single exhaust from the converter back.

    If any of you guys hears some clanging out in the driveway tonight, do not be alarmed - I am borrowing your exhaust system.

    Just buy the Dynomax kit. The Diesel idea is a good one, but unnecessary.
