So whats the deal with the tubular exhaust manifolds and 3" down pipe for the 3sgte on ebay. Are they any good? do they crack? do any of u 6gc members have them?

i also never said that the stock manifold was the best there was for the motor either....full-race will defenitly out perform a stock one...but if all your doing is bending tubes to a cool shape and claiming sum BS number well then thats no good..an improper design (like the one on your car brian) acts like a radiator releasing heat temperature (energy) from the exhaust gases...this causes a power loss..not much but it does...hotter gases = better spool and kinetic energy..with proper design, materials and labor a tubular manifold can be beneficial over the stock...but you can't claim anything (like someone already did) without actually producing 1 and testing it...thats all i'm sayin if your not totally power oriented and you want some bling then by all means its fine...but if your function over form then there is a difference
