I was looking the omp decat system and it says ''OMP exhaust systems have significantly lower back pressure values than the original system. In order to achieve the most power from the exhaust system, it will be necessary to tune the air-fuel mixture appropriately.'' Is janspeed the same. I hope to order my full decat system over the weekend. What happens if its not tuned. which system is best in terms of sound and performance
