Magnaflow.

 

Borla made the kit I installed. And they (Borla) make the off road kit I looked at. I understand why you wanted to claim the Roush....but its a different system than magnaflow. AND it sounds better than any magnaflow Ive ever heard. (I havent heard them all)

 

MAGNAFLOW REP CAN I GET A REPLY ON MY QUESTION THANKS RG

 

You can go with a banks stinger kit, it has ram air intake, catback, and a progamer that wills give you horse power and accomodate your tires. They have the set up on their web site along with a video from Trucks

 

Magnaflow...getting rid of my flowmaster and going stainless. Magnaflow sounds great and its quality.

 

also, for intakes, a K&N intake is all i'll ever run. My F250 has one ( with the Flowmaser si/do ) Good intake, takes in ar & power if very noticeable
