Gday all,

So iv got my self two sets of extractors one is a genie set that are fours into one and the other set is a no name brand that are fours in to two then one. So what i want to know witch one is the better one. it will be going on a supercharged 5k when i get around to it.

Cheers Jamie

I would think the 4-2-1 but we would need to see pics.

+1 but depends if 1&3 2&4 are paired or its different

ill get some pics up tomorrow for you guys

I'd also check out condition. Do both have flat mounting faces? Do ports match up, is there weld and crap sticking into the tubing? What size is the tubing?

When my KE70 was supercharged, I ran 4-1.

 

Cheers, Jake.

four to one with a merge collector is best for high rpms, just ask anyone with a v8.

tri Y style are better for torque + driveability
