The title says it all. Can anyone offer this or at least point me in the right direction?
For
What's the difference performance/sound wise? I want to squeeze as much power as I can. I also have a feeling that the manifolds are much cheaper.
For headers, TTI is generally regarded as the hot setup. However, a lot of us prefer the HP cast iron manifolds.
Good to know! Also I'm assuming with the manifolds, clearance is not an issue?The HP manifolds flow the same numbers as a set of headers. Plus there is the added benefit of not having to deal with exhaust gaskets periodically blowing out on the headers and snuffling away.
I have Hedman shorties on one of my cars, you can read about it here:
Forums / Performance Tech / Hedman shorty header review - C-Body DryDock
Been on for 11 years, not a ton of miles, but no reliability issues or gasket issues in that time. NOTE - gaskets must be sized for the standard head port, not the bigger MaxWedge port, because the sealing surface on these headers is a little smaller than those gaskets, so you can get leaks around a large-port gasket. Other wise known as snuffling. I used copper gaskets (had to search for awhile to get the brand with the right port size) and they have been trouble free!
My nose is clear and my headers don't leak and my fuel mileage is up 1.7 mpg over HP manifolds. Wtf do you guys tighten stuff with minimum 36" breaker bar, your not supposed to drive the header flange through the gasket just clamp it.I just checked, no header snuffling here. Whew.
