just ordered my exhaust now i need to do some before runs to show the change after w/ flowmaster cat back and the dynatech superMaxx headers w/ cat and y-pipe.

 

By all means, give us some numbers. Good luck....

Dynatech is on my long-term Tweak list along with Heads! Like Red said keep us posted!

 

yeah will do my cat back gets here tomorrow

 

As you can see from times posted, the big trucks can be very fast with the right mods.

 

yeah but i only have to right now. can't wait for gears cams heads tb

 

yeah with the cat back i can't get grip i first with out trac ctrl and spin to much in first. my 1/4 mile is fast speed but close 14.83- 14.89 @92-95 vs 14.81 @ 89. will try to get better time and the video up soon. def spin more thought trac ctrl runs are faster but tuner keeps my trac off times. trac on 15.27 @94
at least it is a solid 14.8 truck for now
need tire i guess maybe that will help
