340 headers?
Whew! I just got done with my Hookers. The regular comp series units. There hanging low as normal. I have had far warning and exper. with these clone headers before. I have to say, the Hookers were murderous getting in. But fit great. No denting. I also have in the past used Headman. Same results.
Other manufactures get an "F!" in my book.
But, like I said, it's the typical 3 out of 4 pipes under the linkage deal again.
