The weather has been nice, so I've been driving my gt everywhere. Well I started cleaning the engine and noticed something odd, so I jacked the car up and looked. My DS manifold is actually a little cracked, which would explain the odd sounding exhaust and extra Off road smell. So I am asking those who would be better in line to answer, for replacement, should I pony up some cash and save some weight with shorties, or look for some better conditioned stockers. I know 99% of people say shorties don't do jack sh*t. But I did throw some on my v6 and noted sound, low-mid power and obviously they weigh less. I can't speak for the 4.6, but I did notice a real gain in the street department on my six. But enough of that. I am just looking to replace the cracked manifold. I am keeping my system the same, as I already bought the O/R H, and have decided against long tubes for my current build. So asking you guys' opinion. And if shorties are a decent upgrade, what brand? I've heard hit and miss about BBK and JBA, so looking for some firsthand info. It's not a huge issue as I won't be doing that until I find some heads, and figure I'll do it all at once, but am now in the browsing stage. As always appreciate any input.
