What do the new trucks dyno with this system(4.8 or 5.3)? Is it the 15 to 20 rwhp gain I've heard so much about or is it higher?
The systems look really nice.

There will be no 2" primary unless your making nearly 1000hp or have a 450+ cubic inch LSX you'll be fine with a 1-7/8's we have supercharged corvettes with a 1-7/8's system making 1000hp. It's a short primary around 23" so unless your combo is very extreme you should be fine with the 1=7/8's
