Will later style y pipes and manifolds fit my '84 V6 Mustang?
My '84 3.8 Mustang has a crushed/collapsed y pipe. I looked for aftermarket replacements but everything listed is for '85 and up, or 94 and up. Does it really matter? I've already swapped in a dual hump trans crossmember. If I buy one of these y pipes for an 85 and later Mustang, will it fit?
I'm also wondering if Later factory exhaust manifolds, (or aftermarket headers listed for later 80's mustangs )will bolt up to my engine. For example, some factory 3.8 manifolds off of a '89-93 3.8 mustang ? Did later factory manifolds flow better? Mine are cast iron, and look like they were designed in the 70's.
Any info is greatly appreciated
