i have a godspeed manifold and it is usable. thats about it. the welds are good but they ran the finning to close to the tanks and when they welded the tanks it ate up the ends of the fins. doesn't affect performance, its just ugly. asides from that its just like SSAC.

go megan, at least they are trying to make a good product.

Alright sweet, ill get the megan than I guess... Just heard they crack, but I'm replacing all new exhaust hangers so it has a less chance of cracking ( site says it cracks due to viberation....if anyone has a MR and like it and nothing bad happened let me know

the vibration usually has little to do with it.

make sure you mount your exhaust to your transmission as it comes that way OEM anyway, a downpipe with a flex section, and a support welded on your manifold with make cracking very unlikely.

what happens is the aftermarket downpipes tend to run a bit lower than stock, and when they get hit, all of that force gets transmitted to your exhaust manifold. that is usually what causes the cracking.

you *probably* don't *need* the flex section. my downpipe does not have a flex section and i have not had any problems. however, i am not running a cheap manifold. and if i ever do buy a new one, it will have a flex section just for an extra level of caution.
