See sig for engine combo. Looking for the most power and best sound out my headers. Currently have a set of heddmans. Exaust system will be dual 3" with flowmasters come wensday.

Im about to do the same thing and im getting Edelbrock TES. SLP are obviously the best and will outlast almost any othe brand but you better be willing to pay about 500 for the headers plus the installation kit. The TES headers are only alittle over 300 and they come with everything you need. But if you have the money go SLP.

Definitely the SLP 1 3/4". The Edelcrock's are too small and restrictive.

If youre running dual exhaust, why not go with the hooker super comps? They have 1 3/4 primaries Thats what im running on my exhaust and theyre a lot cheaper than TES and SLP

...Whatever turns your tires.....

 

No longer getting dual exhaust damn muffler shop backed out at last sec said I'd have about 1" clearance between road and mufflers. So I'm no planing on going with a single 4" system from mufflex. Exhaust shops around my area are not willing to try to put on dual exhaust unless u use supertraps, glasspacks,or a bullet style muffler,and I don't like the sound of them.
seriously thinking bout super comps despite the non dual settup heard some good things bout them.

Man, that sucks about muffler shops...the lowest point of my whole system is 4" from the pavement. They obviously dont know what theyre doing. I would use the super comps...theyre a great set for the money.

how much are a set of hooker headerss 1 3/4?

------------------
Wide Open Till You See God...Then Brake

 

hooker super comps are about 360 bucks and if you want them ceramic coated, about 500 ore more

 

well im doing a 500 hp 406 and i picked the slp's for the simple fact that id rather have the best now then a few years down the road when the others go bad.
