ASM headers and Magnaflow Cat-Back are installed and all I can say is WOOOW the truck feels so different, it's faster than I thought.
For those guys that haven't decide which muffler to buy, the sound of the magnaflow is great it has a nice rumble at high revs and you can barely hear it when cruising or at idle. The truck runs great, that header cat-back combo is really giving the airflow that the radix needs, I can't wait to put that 03 LS1edit tunning on the truck and get the most of it.
I highly recommend this cat-back (single in and out)and the ASM headers believe me you won't regret it. Just for you guys to know.
I hope it doesn't rain tomorrow to bring some track times, I'll let you know.
Thanks.
