i have the mugen exhaust currently on my car but from the cat back to resonator it bottle necks and i dont want to cut it. (big waste of a thousand) so if i do decide to get the sms or hytech ill just sell it for a good amount of money. but if i do keep the mugen ill get the jdm 4-1. im just exploring my options.
im leaning towards the hybrid system
so...where's the cheapest place where i can get the jdm header and what would be a good price for the recaro srd (black) in good condition
