Sanderson and TTI are the only companies that make specific short headers that fit. TTI sells the head pipes for theirs as well. If your considering long tube headers, Doug's and TTI are the only companies that make a log tube that does not hang low, i.e. tube under the steering linkage. A 90'd 5.2 Dakota or Full size truck/Van 5.2/5.9 mini starter helps with room.
Is your car an auto or manual, Column or floor shift?
