you might wanna delete that ^^ reply, as you cant sell anything yet
2nd you spelt your thread name wrong its canon ...
and yes you did loose power due to 4inch tip... who did this for you?
and did you choose the 4inch tip ?
maybe you need to learn to spell too. its a 'cannon' not a 'canon'
dont think the size of the tip matters as much as the size of the piping?
nothing wrong with going upto 3inches in an NA car. i went 2.5 mandrel because i kne of the BIG NA plans i had in advance and require the breathing space.
as for back pressure, yes you lost quite a bit for a marginal gain in top end. lucky for you that you got a cannon. you can purchase the N1 silencer designs seperately in your size and plug it in.... gave me enough backpressure back
