Possibly! tho im replacing the muffler on mine as since i took the cat converter out it has more sound going into the stock muffler which sounds lovely under 3000rpm after that it sounds like it has a screwed up baffle and bad as rasp!.
Hopefuly the muffler the shop puts on has a nice growl to it, i trust the shop and have been there before, love the fact they have 6 rally cars in there shop!.
Ill upload a video of the exhaust once completed as i know everyone loves to listen to that isuzu engine growl ( ive prob watched Rickshaws exhaust videos 100s of times now)
