i have 02 4.6 auto for your info
with BBK Extractor Series X-Chamber Mid-Pipes

 

FIrst learn grammer and then use search

 

hahaha

why nothing is understood ?

 

R u actually in bahrain?

Long tubes r going to be ur best gains.

The difference between the 2 is one is ceramic coated one is not. Ceramic keeps heat dowm

 

Long tubes or keep the manifolds, shortys aren't even worth the trouble installing on a mod motor.

 

All you need to know is do long tubes or don't do them at all.

 

but my x pipe its not working with long
i have this pipe

Either buy a shorty mid pipe specifically made for long tube headers, or just keep what you have for now and don't do headers at all.

 

Long tube headers will make great power and improved throttle response. Obviously Stainless steel is the best available material as it will not rust!

 

Stainless also has much lower thermal conductivity than other steels, which helps reduce under hood temperatures--more important than not rusting to me...
