I was looking at getting 5' exaust for my truck, but i've been told that I'll loose bottom end and fuel mileage.Does anyone have any info on a good kit that will give me a power gain and hold up to future upgrades like a bigger turbo and 90hp injectors.

 

unless your pushing over 550-600hp. . .a 4" kit is all you will need. silverline or MBRP have some good ones.

 

Is the sound better? will I loose throttle response by going bigger?

 

I want to hear the turbo. some trucks sound like jets taking off, what kit is best for that?
