i do have up for fs listed a modified ztube, this is the oem gtube that i have severed off the resonator and sealed it off completely for good, so in essence it's a ztube but oem so it will look good with your engine cover, make me an offer total shipped

the mod gtube is very stable, the resonator hole covering piece is much larger than the hole, and the material is quite thick, the bondo is on there for good - it and the cover ain't comming off or break loose unless you wanna destroy the entire gtube with it, gl
