I researched quite a bit last week looking for an exhaust that would have a nice tone and growl when getting on it but remain at tolerable noise levels for daily driving.
I decided on the Aero Turbine 2525XL (2.5" inlet and outlet with resonator) rather than the unresonated model. I had them install it to where it dumps just before the axle.
My local shop did it very nicely with 3 hangers and clean welds for $80.
When idling and just cruising around town the tone is slightly deeper but only a tiny bit louder. If you give it a moderate amount of gas you definitely notice the growl and if you stomp on it it roars like a beast.
Exactly what I was looking for.
If you want something that will be more aggressive at all RPM's id say get the unresonated model.
Ill put up a picture of the install later today
