Not to deter you from headers, but I still have bad dreams from when I installed mine.

 

Headers are useless on a N/A 5vzfe engine. and so is duel exhaust.

 

so save money for a s/c? headers wont do anything on a 3.4? man!

 

useless on a N/A engine, but what kind of gains could one expect to see with a supercharger? I want to build everything up this summer in preparation for the supercharger next summer, and I am exploring my options. I want a moderatly price, decently performing exhaust, and I was wondering if I will really get the bang for my buck I am looking for with these headers. Or should I just replace everything from the back to the front, stopping just short of doing the headers?

 

i have a midly built 3.4 and run Doug Thorleys. They havent leaked yet but i only have about 3k miles on them. I did like the quality though and went with ceramic coated ones.

And it only took me an hour to put mine on (The motor was out of the truck )
