Which headers would make more power on an H/C 346ci? And which are better. Kooks 1 7/8ths or LG Streets?

 

I am going to venture the LGs will give you more power. Their site claims the 1 /3/4" primary size is just fine for power under the curve (BTW- Borla manufactures the LTs for them I believe) but I've read good results with Kooks too. It would seem the smaller LGs will give a bit better drivability around town and wouldn't give up much (if anything) in the upper RPMs.

JMHO.
