Anyone used the GT X-Pipe, part no. M-5251-M8 to do a resonator delete on their GT350? If so, is it a direct replacement or does the GT pipe need to be cut? There are some after market pipes out there, but I'd like to stick with Ford parts on the GT350. Ideally, I'd like to purchase the X-pipe from the R, but it looks like Ford parts has no exhaust components available on either the GT350 or the R. The current X-pipe on there appears to be just clamped on with no welding involved. Is that correct? Thanks for your input.
