Ok I just recently started noticing my engine is being extremely loud when decelerating and not wanting to come down from rpms when slowing down. Il be slowing down from like 45 and around 10 mph it's still loud where as before the rpms had come all the way down already. What do you think? Ive had my exhaust on for like 5 months now and love the exhaust sound but it hasn't sounded like this until a few weeks ago, it doesn't sound like exhaust noise its like the engine rpms are just slow to come down.
