4.6is straight pipe with x-pipe.
hey guys. as some of you may already know, i had the mufflers removed recently... and the RUMBLING sound is AWESOME! it's the sound that i expected before when i had the resonator removed, but didn't make any difference in the sound... but after the mufflers gone, it sounds great. unfortunately, i lost back pressure and it's running like a four banger, very low torque. i also lost 30% mileage means that i consume more gas since i floor the pedal to gain speed at freeway entrances and/or stop lights. it's terrible! i want to keep the rumble but i want my torque and mileage back. i still have the original muffs and the resonator. i heard about Eisenmann but it's just way out of my budget right now. are any alternatives to eisenmanns?
Got any ideas? thanx!
