Short answer, yes.

I have kooks 1 3/4 no cats with 3" exhaust.

Heartbeat blower with cam, only 6psi and Im at 581whp on a mustang dyno. Sure you could gain another few ponies up top with 1 7/8, but to me its not worth the $1000+ for a new set of headers.

I'm in the same boat. Pfadt 1 3/4". Would love to bolt on a set of LG or ARH 1 7/8"s (I think they are the two best) but can't justify spending another $2K+ (for me, since I'm overseas) for the upgrade, for just a few extra ponies. If I could find someone that would buy my headers, I would probably do it though.
