wow good call joe i was maybe 30 seconds into buying one lol. Yeah im thinking now maybe str8 them. But might just take the whole thing off and run shorties. Thanks for help guys.

The thicker the flange the better, if you don't go with 3/8' flange I would think about these http://www.summitracing.com/parts/JEX-FLX3010B/

Nothings worst than spending all that money and 6 months later you have a warped or cracked header, plus for the price they look really cool.

what i did was get a collector extension kit from jegs, have them bent like the stock pipes are and voila, true duals with no y pipe. But mine dump right where the bed starts. But if you want your pipes to exit by the bumper, you have to have them side by side cause of the tank.

is this what you got? http://www.jegs.com/i/Hedman/500/69440/10002/-1

[AverageJoe]

no, i got these shorties http://www.summitracing.com/parts/BIG-11504FLT/

And then these and bent them how i wanted them http://www.jegs.com/i/JEGS/555/30631/10002/-1

then welded my mufflers at the end of those with turndowns, it comes out right at the beginning of the bed though.

Cheaper than a muffler shop, but i do all my own stuff.

It should fit in place of the factory ones, but its 3" collector

[benoit454]

The ones I bought from ebay instainless for $122 shipped fit directly in place of the stock manifolds and the top side is a very thick flange has to be at least 3/8 or so. The collector is thick as well and as mentioned uses no gaskets it's ball end to fit in place of the stock manifolds and bolt to stock pipes without a donut gasket. I love em.

[AverageJoe]

could you look those up for us?

Sweet, thanks man. About how long did it take to install and how happy are you with them? (The one that you got http://cgi.ebay.com/ebaymotors/Chevy...Q5fAccessories )

[benoit454]

I'm very happy with them, mine had duals and I didn't have a welder fo I didn't want to cut or weld anything, as for bolting thwem on not long. About as long as it'd take to remove the 3 lower bolts and the 6 upper bolts on each side, maybe a couple hours or so if that but mine had been off recently. If the manifolds aint been off might take a little longer. I removed all my plugs so I wouldn't drop one and break a plug, and that was the biggest PITA of the whole job putting the back 2 plugs in on either side. You need an offset 5/8 or short 5/8's socket made for plugs that let's you use a wrench on, but I got by with a regular box end 5/8 it just took some time.

[Chevy350V8]

Well i found out that i need some rear lights and high beam lights. Im going to try and get the bed armoured and clean up the cab corenrs. There not rusty just a little surface rust. I can post pics a little later when i get it done. Im using coke and rust stoppage black paint. Any one else have a better way? Thanks
