Japspeed exhaust question
Ive got the 3" full system on the car with 4" backbox? It sounds lovely and i dont think its too loud, but. Next month im venturing on track (105db). I was wondering what backbox would fit to make it a touch quieter if needs be?. Im going to nip over hopefully next week to get it sound tested but thought id ask before hand just in case.
