No way, headers are great! But the word of the day here on Sesame Street is: TURBO! The way I see it is that it's easier, and cheaper to replace the Quaife before your 3l install than it is to purchase a set of headers. There usually is not a waiting period for the Quaife(headers took about 1.5 months), and the Quaife is cheaper! $595+shipping instead of the new header price $660+shipping. So the offer is on the table, they have about 800 miles on them, and are pretty sick! Or, we could trade for 5 Benjamins????
