Hey all, i think the noise i've heard upon accelerating from 2500-2900 RPM is a thin metal heatshield that goes over the pass side exhaust manifold. it is super rusty and loose because it looks like some straps or mounts are broken. trouble is, i can't find this shield in the part manual - all i see are two shields that go on top of the crossover pipes in back... or is the right one the one that i need? doesn't look like the right shape though. the thing that is loose on mine wraps around the manifold. i'm guessing this is something i should leave to an exhaust repairman to fix, what with all the old rusty exhaust hardware around there. does anyone know what i'm talking about here? or is this a job that i should be able to do? (i'm pretty handy but not when studs break off....) Later, Andy Soma576@xxxx 1982 DeLorean DMC-12 VIN#11596 Fargo, ND 58102 [Non-text portions of this message have been removed]
