I have the unleashed catless DP, LMS 4+ tune, K&N CAI, NGK plugs and original exhaust and I like the whoosh sound my car makes. I think if you want that throaty sound you have to have a V8 naturally aspirated engine. Gotta embrace the twin turbo sound! The performance is unbelievable and with EBC slotted and drilled rotors and performance pads its like own SHO 2.0. Loving it!
