So, ive got a v35 2003 that has a rear sports muffler and HFC's with the rest stock. It sounds decent but is a bit quiet as higher revs like 4-6k or probs quite in general. Ive tried doing a res delete and it sounded tinny so i put it back on and i know the front muffler delete will do the same thing. Is there any other options to make this beast louder?
And secondly, im getting around 380-400kms on 1 tank of fuel. So either my needle is off on the fuel gauge or there's something wrong. Is this a common thing?
