I have a pretty big exhaust leak towards the front of the car its sooooo loud, thats what i can describe i put some tape on the over it and it blew it off in two days. Whats a good price to get it fix. O i put the new ecu in and so far perfect. No stalling ,power is back at high speeds, doesn't shut off at all. Took it on a 30 min cruise and it did great no problem what so ever. I just pray to God it keeps up.
