Bro.. Care to explain? Got such thing as trumpet tuned for low-end torque? I thought once we go trumpet, we can forget about low end already? Can we still get low-end torque if use trumpet?

And... lets say we use long and slim ones, which is for low-end torque, is it better than the low end torque for stock filter/open pod/CAI?

Thank you...

of course ... matter of fact ... changing to CAI/exhaust also it would be proper if u do tuning ... then only u can fully utilise it :)
