what is the loudest exhaust system i can put on a car its a 1984 oldsmobile cutlass supreme?
I have used Rain-X and it works very well, however it seems to leave streaks.maybe doing something wrong in the application. You wil notice a marked difference after using it and I think its a good to excellent product.
loudmouth catback or flowmaster
how about no exhaust? they make an exhaust system that opens a door and makes the exhaust come out a different pipe so it avoided the Cadillac converter and muffler, and by a press of a button you can switch it back to the original way so i can still pass smog and cops wont bug you
