...This is not the case however. In my opinion it is quite loud in the cabin. I'm running Gruppe-S UEL, stock FP, stock OP, Greddy SP Elite. During acceleration it is challenging to have a conversation. With that being said, I can cruise at very low volume, and there is little drone.

Had a buddy drive the car to show off today:

- Drive-by

I think the tone is great, but i'd like to lower the volume a tad. I'm under the impression that this won't be easy to do, as the Greddy seems to be nearly as 'quiet' as the q300 in popular opinion. Is there another way that I could lower the volume of the Greddy (perhaps by adding a resonator?). I'd like to retain the UEL header for the torque benefits.

Thoughts?

The topspeed pro-1 is a Greddy elite SP clone, the greddy sp elite isn't actually being built any more . In fact my build involves installing a topspeed pro 1 eventually and yours sounds quite good. You're car is about as quiet as can be with just an axleback and uel, I can only think of getting a HKS dual resonated front pipe but then you'll be fully catless and that may be a problem with emissions for you.
