GTS Flash
Hi guys
I have a 67 plate M4 Comp and am thinking of getting the GTS flash when the warranty runs out.
Any thoughts on this in terms of the improvement it will have and also would this increase the pops and crackles or any other ways to increase the pops and crackles without any exhuast modifications.
For the GTS flash, any suggestions on who to best carry this out?
Thanks in advance
