i have read thread after thread trying to find the best solution to my problem and i have finally decided to just post a thread of my own. here's the short and skinny...i had a muffler shop (recommended by a friend) install a custom exhaust. all he did was put a mellotone muffler in there with single 2.5 inch in and dual 2.25 inch out. i thought i would get power but instead i lost it! i mean it sounds good but what good is sound if i cant back it up?! i can barely even spin my tires anymore! power is more important to me than sound. basically, how can i get the most power (mainly torque) out of an exhaust? Where should i go, what should i buy, or what should i do to it? i have a CAI and im willing to change the entire exhaust around again. feel free to throw any other power mod suggestions too as i will likely do something else to my truck in the near future. come on guys...give me power!! thanks in advance.
