Yes he had stock 99+ pi cams/heads/intake. he did however had a plenum and a 75 mm t/b.

I say get em. The thing 4.6 is talking about is only with the 4v cars. The headers tend to scavenge too much oil and car it to burn oil and another problem was from the slag getting sucked into the egr, engine, etc and wreaking havoc. Everyone Ive heard of with Macs on a 2v car are extremely happy. I say go for it.

A dealer header install will run you 600 bucks easy.. they are a pain in the *** - but you can do it and you don thave to drop the suspension... I think something is wrong with your tuner - ur dyno or your car if only get 5h from a tune... my LTs made a bigger difference to me than my 4.10 - i have macs w/ no cats - love em sound awsome w/ no problems a freer flowing engine never fuked up anything.. dont listen to any old retard about your car.. people say some dumb ****...
