I agree, Hooker, Hedmen and TPIS are all 4 into 1 type. Never seen Tri-y for a C4 before.

It was mostly due to the new 383 they were attached to!  :evil  ;39

Pacemaker make then for C4s ,both mirror and chain drive conversion
Part # 5300 /5301   (1 +3/4 only (1+5/8 special order)

Any exhaust shop should be able to order them.
Approx $800 but a dealer on eBay was doing them for $550 earlier this year.

Conventional 4 into 1 ,header flange is approx 20mm below floor pan.Mine is lower than stock with Z51 susp and have not hit them yet.Perfect fit , no 2 plug is a bitch as pipe bends back and in over plug to clear steering shaft.

Thunder Kiss:
Pacemaker, very interesting.
More info here.  They're mandrel bent with no AIR pump lines and it says you need a hi torque starter as they may not clear the original one.

I'd love to see pics 87Z51.
