I agree. I had a K40 in a Corvette and thought it was great...until I got a V1. The V1 is far superior in all bands. Sure, it looks funky, but so does a speeding ticket on your driving record.Originally posted by AndyMenard:
I owned an M3 in a past life with the stealth K40 system including the diffuser. I thought I had a good system until I bought a Valentine 1 for one of my other vehicles. The V1 kicks the crap out of the K40! It is just not as stealth and therefore maybe not as high on the "coolness" factor?!
I would get the V1 and use the money you save to buy other upgrades for your M5!
my 2 cents.
