1st 2014 truck to get 0 to 60 in under 5 secs. Magnussen with ARH head

[Boombastic]

Just got The truck back from the shop yesterday. My truck is a 2014 Sierra Denali 6.2 liter with 3:42 gears. We just added American racing headers to it. Some of othe performance companies were telling there customers that The addition of headers to the supercharger wasn't going to make much of a difference. We Dynoed the truck with just the Magnuson TVs 1900 and got 415rwhp. With the addition of the headers we gain 30 hp at the wheels. The final numbers were 445 RWHP and 491 torque.

I will be doing the same thing probably Edelbrock SC. Can you tell me the pipe dimension at the Y pipe out let for the 6.2 3" or 3 1/2" I already did a custom exhaust and went with 3 1/2" there web site says 3". I called them and they said 3 1/2" for the 6.2 I hope so. Thanks for any info you have.

Or on top of the truck.

Yep, no problem.. One from the top would be easier. What are you looking for?
