I have heard the SS headers are a 1 1/2 primary tube, and the CAT are 1 5/8
primary tubes. The SS tubes may be small for aftermarket heads. A higher
performance build, especially if using aftermarket heads with larger port size
may need the the larger tube size to assure that the ports on the heads are
not partially blocked. I have heard both headers are good, higher performance
builds may want to consider the CAT headers, they will probably support a
little more horsepower.

Subject: Re: [Tigers] Which header?
Can't speak to any power gain, but I can verify that the Sunbeam Specialties
headers fit with no modification on my Mark 2. Tight, but they fit. There's
some confusion about which headers Classic MotorSports used in their Tiger
build. One time they mentioned SS, the other, C.A.T.. They had to modify a
motor mount, if memory serves. Maybe Mr. Suddard will offer a comment.
