You don't want 1 7/8 headers without large cubes.

I am thinking about N20 as well. Will I benefit then or do I still need a bigger motor than a 346? Thanks.

You could use them if you were going with a big cam, were going to use nitrous alot, and if you were mostly ONLY interested in top hp gains with sacrificing low end TQ.

After going back and forth I've finally decided to go with the LG Streets. 02 Z06 that will probably never go beyond bolt on items. I did a lot of reading and also called LG (and a couple other vendors). I don't think I'm giving up anything going with the Streets on my application and the current deal is pretty good bang for the buck.

Just my .02 or in this case my $895

I have the LG Streets and I'm happy with them overall. For a few extra bucks (few hundred actually) you can set up to the American Racing ones which have a little better build quality and ball flanges.

LG's and AR's are going to give you similar hp and similar difficulty (or fun) installing.

I would do the American Racing headers hands down. All the tuners I have spoke to are raving about them. Give Carmen at The Vette Doctors a call..

EBAY HEADERS...... Well, they are cheap as hell, make power, sound good, and are made of stainless.








I run kooks 1 7/8 though.

I have Kook 1 3/4 they have been good. But recently had the air tube break off of the primary on the driver side.

Do a search and see if this is happening on the others you are considering.
