Anybody using them? http://www.speedwaymotors.com/p/5425,415_SandB-Chevy-Stainless-Tru-Ram-Exhaust-Manifolds.html I'm wanting to get rid of the leaky headers that are on my Suburban & the price of even after market stock style manifolds are gonna cost about $200 - $250 new. Vett Manifolds from the dealer that are for the 2.5" exhaust will run about $300-$350. I like that I can get the Tru-Ram manifolds in stainless & it looks like it would be a piece of cake to change the spark plugs too.

Those aren't going to fit very good nor are they going to perform very well compared to a good set of headers. Your exhaust would have to be extremely tight with the manifold exiting in the center due to the crossmember. Not sure if you have 2 or 4WD. I had a set of these style manifolds on an older K10 I had. If your headers don't seal well I'd opt for a better quality set.

i agree with the fitment part there. they will be a little tougt to fit. but i dont agree with the performance part. i had a buddy that had them after hedders and i noticed no difference at all. just my opinion.

My Suburban is a 2wd & looks like I've got plenty of room for the exhaust dump. I don't like the headers on my Suburban now because they have rusted threw & hang lower than the frame. I'm gonna make a new crossmember for the transmission when I swap in my 700R4 & do something with the drive shaft center support crossmember to keep the exhaust above the frame.

I'd suggest you just buy a higher quality set of headers for about the same price..those manifolds take up more room than you think. You'll have a REALLY sharp bend in the pipe to get around the cross member. From what I've seen, engines with rams horn manifolds like those don't perform as well as a GOOD set of headers. Ceramic coated, especially ceramic coated stainless, wont rust, and if they're a good set, they don't have any clearance issues.

I'm not to concerned with performance, I'm more concerned with future exhaust leaks & accessibility to spark plugs for future tune ups. I'm all over the "go fast", now days I'm into draggin' my trail rig through the rocks as slow as possible. The Suburban is going to be my new daily driver / tow vehicle / family travel vehicle, I just can't do anymore long trips in the wife's Honda Civic, even if i does get 35 MPG.

I'd still go with good headers or stock cast iron manifolds..those rams horn manifolds REALLY don't look like they fit well on these trucks...I'll bet you can find some stock manifolds at the junkyard for like $40..

Yeah, the Good Guys car shows coming up quick here & there will be swap meets too. I was thinking about trying to find some Vette ram horns or truck ones with out the smog tube tap holes in them.
