I would like to see what they did with the driver's side exhaust pipe. Is it still squished where it goes over the torsion bar crossmember?

 

Post back when they're in stock if you don't mind.

 

How do they match up with the ASM

 

The AS+M headers are a very good product. The SuperMaxx is the only package that comes with high flow cats and a Y-pipe.

We have 3 sets left out of the order that will be arriving this week.

 

Can they be ordered without the cats and y pipe?

You can get the headers only -

2000-'04 4.8, 5.3 6.0 GM Truck / SUV headers only

They did some testing on a totally stock 4.8. That truck picked up 17hp.

 

so the ASM will give you more hp and TQ
