I'm looking at getting headers for my 86 tpi irocz and was wondering which ones were the best i also need a y pipe

 

The SLPs are the best, but most people use the Edelbrock TES and are very happy with them. Both are sold in Summit.

TH 700R-4 Transmission with 2.77:1 Rear End

Current Mods: Edelbrock TES 1 5/8" Headers, Hooker 3" Aerochamber Cat-Back System, Performance Resource Chip with 160* Thermostat, Accel Ignition Coil, Cap, Rotor, 8.8mm Wires, K&N Filters, JET TPI Air Foil, All Free Mods, Falken ZIEX Z-Rated Tires.

Best ET : 14.32 @ 97.7mph
(corrected for elevation)

Next on the list: LT4 HOT Cam

 

All I've got to say is Hooker Headers hands down. Ask any exhaust shop which is the best & they will say it's Hooker (well that's what all the exhaust shops that I went to said).

This is a tuff one. Everyone who has gone with SLP says SLP. Everyone who gas gone Edelbrock says Edelbrock and same goes for Hooker. Only time I ever heard anyone complain is when they didn't coat there Edelbrock TES headers and they rusted out. Same goes for hooker. If u get Hooker or Edelbrock TES Headers, make sure u get them coated. Its worth every penny.
