That's assuming that the company making the header actually makes it differently for the VTEC and non-VTEC Integras. Cookie-cutter header and exhaust systems are so common. Imagine my surprise when the Comptech header and exhaust I ordered for my Type R was the same one they were selling for the LS. Took the header back but unfortunately I was stuck with the exhaust (which BTW was the same size as my STOCK exhaust and did absolutely nothing but make noise).MichaelDelaney on Mar/22/04 said:I would not even recommend to my enemies to put an LS header on a 1.8L VTEC motor. The higher powerband location on the VTEC motors would get stiffled.
