has anyone heard of this godspeed exhaust system?
I am looking for an exhaust and I came across this one....it says gain 15 hp and 20+ torque and all this for only around $600. I must be dreaming or either gullible, can anyone help me out on this exhaust?

 

you are a gullible retard.

 

Now see, I have seen quite a few ppl on 350Zdriver saying they liked it and it was a good exhaust

 

That may be, but it sure won't get you close to those advertised gains.

 

Yeah I think those gains may be a little exaggerated but good luck. Tell us if you see anything close to those numbers. I personally love the growl and quality of the HKS.

 

Hmm... I remember seeing tanabe has that power band for the G37... with dyno proof also.

 

Never trust what the manufacturers say. All they want to do is just sell it. Bolt ons won't get you much power
