I heared the GruppeM sounds great when over 5k ?

HKS RSK or a Martelius Exhaust. Either way they both sound the business.

CPL CAI sounds great as well.

You only buy GruppeM for performance. I heared it and it sounds the same as stock. Looks nice though

2x 15inch subs... high power 6x9's and a couple 6x6's ... then record some car sounds from youtube... put them on a CD or USB stick (09 models are older) then play whatever sound you fancy at the time... best of all worlds =)
