12600526 MANIFOLD. Engine Exhaust Manifold - LH. Required: 01LHD.
12600527 MANIFOLD. Engine Exhaust Manifold - RH. Required: 01RHD.

Wow, good prices. GMpartsdirect generally kills you on shipping though. Check out the build thread index-- I know there are a few running them in there for sure. Or, do a search for TBSS...

I used them, Only clearance issue was between the motor mounts and the manifolds. I shaved the bump off of the mounts. Others just do a little clearanceing with a grinder.

Re: TBSS Exhaust Manifold Info (Pictures)
 

I'm using TBSS manifolds with dirty dingo adjustable 73+ mounts with the matching stands and rubber. They fit great with zero issues, they are not even close to the mounts or stands. I did notice the part numbers cast on mine are 12567483(LT) & 12567484(RT). Not sure what the difference is.

Re: TBSS Exhaust Manifold Info (Pictures)
 

They charge $25.41 to ship them for a total of $125 so not too bad if you don't have maninfolds that work already.

Re: TBSS Exhaust Manifold Info (Pictures)
 

Does anybody know it the GMparts direct manifolds come with the heat shields?

Re: TBSS Exhaust Manifold Info (Pictures)
 

Lists a seperate part number...in my experience with them, anything listed separate that doesn't have a "*, kit, package" listed means its the item ala carte. I would expect to get the manifold alone, no studs no heatshield.

Re: TBSS Exhaust Manifold Info (Pictures)
 

They don't ship to Canada!! AAAAAHhh!!

Re: TBSS Exhaust Manifold Info (Pictures)
 

Those two part numbers list as Chevy SSR truck manifolds...

Re: TBSS Exhaust Manifold Info (Pictures)
 

I do! ...and mine come with heat shields and pipes...

Same engine, same chassis, stands to reason same manifolds. Never look at an SSR the same again...

2004+ GTO : 12563277 and 12563278
They look like they tuck close to the block and ont have two vertical studs. Should be plenty of frame clearance...

Re: Stock Manifold Options for LS Swaps
 

Any input on which (if any) manifolds for a stock '57 front end?

Re: Stock Manifold Options for LS Swaps
 

Didnt the ssr have different heads with d port on exhaust ?

Re: Stock Manifold Options for LS Swaps
 

I dont believe so. They started in 2003 with the 5.3L so it should be round port exhaust....

PS: I have a pair of 5th Gen Camaro manifolds on the way. I'll post pics when I get them...

Re: Stock Manifold Options for LS Swaps
 

Also test fit the 2010 Camaro manifold... Camaro on the left, Sierra on the right...

Re: Stock Manifold Options for LS Swaps
 

Anyone know if the TBSS manifolds will fit with a 5.3/Dropmember set up?

Re: Stock Manifold Options for LS Swaps
 

Anyone?? Can't seem to find what headers guys are running in the squares, with DM and LS Swap....

Re: Stock Manifold Options for LS Swaps
 

Its 7" from the last manifold bolt on the head straight down to the flat gasket surface of the flange.
It sticks out 5.25" from the side of the block at its widest point. (Opposte of where the starter would attach.)

Re: Stock Manifold Options for LS Swaps
 

does anybody know if the stock LM7 flange fits the TBSS manifolds?
i see they are both three bolt flanges, i was wondering if i could get that lucky. i need a set of manifolds, but was hoping to still use the pipe and flanges.
i know i will have to cut the pipes loose from the y so they will fit in the frame.

Re: Stock Manifold Options for LS Swaps
 

The ones I have bolted right up. I think I have the SSR manifolds but they are identical to the TBSS ones

Re: Stock Manifold Options for LS Swaps
 

What are people using for reducers/collectors for the TBSS Manifolds? Do I have to find a TB and grab the exhaust system off of it, or is there an aftermarket piece?

Re: Stock Manifold Options for LS Swaps
 

Anyone? :uhmk:

I wonder if an exhaust shop can fab some collectors for the manifolds?

Re: Stock Manifold Options for LS Swaps
 

I unded up using the Camaro 2 bolt manifolds but I had the local waterjust guy cut two 3/8" steel flanges for a 2.5" OD exhaust pipe....

Re: Stock Manifold Options for LS Swaps
 

Ya, looks like I'm just going to have some made, or make my own ;P... Thanks mcm

Re: Stock Manifold Options for LS Swaps
 

Thanks guys, all good info for making a "right" decision!!
5.3 2006 going into my "new" 78 Silverado

Re: TBSS Exhaust Manifold Info (Pictures)
 

I just received my Dirty Dingo motor mounts and compressor mount, but no instructions for the bag of bolts!
Could you show me a pic of the compressor mounted and the idler?

Thanks

Re: Stock Manifold Options for LS Swaps
 

GM part number 9220232 is for a 2010 Camaro exhaust manifold collector gasket. Its a metal (looks like stainless) gasket with crush ring of what looks like the old stlye (think lead and brillo pad) material... It has the 2.5" inner diameter.

I also bought a FelPro gasket of the same design but for a 3" diameter exhaust. I may make another set of flanges with the 3" hole. I only bought them becasue I thought they were the correct ones but couldn't get the dimensions. Not cheap at $18 each so I'll see if I can make them work for a 3" exhaust....

Re: Stock Manifold Options for LS Swaps
 

i went to my local napa store for the gaskets and exhaust studs and nuts.
studs and nuts are the same without the hex end on the stud.

and i did cut off the factory LM7 y-pipes and they do fit TBSS manifolds.

Re: Stock Manifold Options for LS Swaps
 

How thick are the flanges on the TBSS Manifolds at the head?

Re: Stock Manifold Options for LS Swaps
 

I tried to order a set of these online through one of the online GM parts suppliers,and after the order was processed,was told that the left hand manifold #12600526 was not available,with no date for availability.Following up,they tell me it is most likely that the left TBSS manifold has been discontinued.Being that these manifolds was used on a fairly limited amount of vehicles it is likely that GM will just sell what is left,and that will be it.The right hand and heat shields are currently available.

Dorman has an aftermarket manifold,appears to be the same,but is more than double the cost.

You guys thing these would work as we'll ?

Re: Stock Manifold Options for LS Swaps
 

They seem to have the same basic profile as the 2010+ Camaro manifolds. I wouldn't spend the $400+ USD... They build Camaros in Canada.... find some take off manifolds...

Re: Stock Manifold Options for LS Swaps
 

my stock l92 manifold will clear passenger side of my 77 but drivers side collectors empties into my frame rail...gonna check out if i can find 2010 up camaro ss or tbss manifolds...

Re: Stock Manifold Options for LS Swaps
 

i just ordered tbss manifolds from gm parts direct. 129 shipped. no indication of back order. used Camaro manifolds on ebay $135. + and i would have to get down pipes i have flanges and down pipes.

Re: Stock Manifold Options for LS Swaps
 

I'm looking at buying an 04 2500HD with 6.0/4L80E. Will the stock manifolds on it not fit my '73 C20? Can a little clearancing be done? Probably going with the Dirty Dingo sliders, no AC.
