how to improve engine breathing exhaust out? my cats are cancelled and i had the rear muffler taken out all i have now is the middle muffler and now i have it double pipes out but seems to be a bit noisy, yesterday it didnt have the middle muffler just the rear one with one exhaust pipe it was quieter and i dont know what to tell u about better performance or not cause its raining all day today so i cant realy say but what am i suposed to expect by shifting the vehicles muffler being the big one in the back to the medium sized one in the middle; other then being noisier hehe
