Magnaflow or Catco both have well-proven hi-flow cats

 

How do i know if it has air injection or not? there is a bung on the header right?

 

Here...read this again:

 

thanks man. it dosnt have that so so far cheapest price i can get for headers and the y pipe shipped is 428 from summit. it comes in stainless also which is good

 

Ok the truck didnt have air injection. so ordered the edelbrock tes from summit 425 shipped for headers and y pipe.

now how much louder will the truck be with the edelbrock headers and y pipe with the high flow 3 inch cat?

 

well put the headers in and the ypipe good to go along with the magnaflow 3 inch hi flow cat. i drove it around way to loud lol i have to get a 3 inch pipe that will connect to the flowmaster thats on the truck thanks guys

Werd on the Edelbrocks!! They are by far IMO the best shorty(CARB) headers on the market. Just get the ceramic coating for cooler temps under the hood. Also, a CAI ain't going to make a big difference on a TBI engine, I just put a open element K&N on mine 14x4" when I still had TBI on my truck.
