    what exhaust do i want?

    Ok, I am tired of my quiet single side exit exhaust. I want to convert over to duel exit. I am getting pace setter headers soon, and since i want to go to duel exit exhaust, should i get the 05-06 midpipes for them? Then just have an exhaust shop weld me in some mufflers and have them run the pipes out the back? Thats probably the cheap method. The easier method would be to buy an 05-06 catback, but i dont wanna spend that kind of money on top of the $600 im spending on the headers and mids. Second question is, which mufflers should i weld in? I want to have some sound on the inside, and i want people to hear me coming on the outside, but nothing extremely annoying. Im hear spintech are good. Thanks guys

    Find you some Polished SS Magnaflow Mufflers. I cut the resonator and replaced with 3in and replaced my stock rear muffler with a Polished 3in Magnaflow. It sounds GREAT!!

    I had SW LTs(No cats) with a Magnaflow catback on my gto. Sounded AWESOME!!!! It was suttle when cruising and mean when mashing the throttle.

    Sarge, i want for it to exit out both sides. Also, they bent those pipes UNDER your axle? Thats wierd, you have no issues with that? I may consider the LMIIs. I hear they arent as loud and raspy as the LMIs.

    with the IRS, you can run tight under the axles on each side of it and have absolutly no clearance loss.....i ran 3" bullets " off the headers, then into 2, 3" flowmaster super 44's and basicly two 3" strait pieces all the way out the back. sounds great and the bullets keep the volume inside tolerable

    I'd say just go for the Borla dual exit like mine but it isn't cheap.

    why not just stick with the same side exit? A lot less hassles and it's still true duals out that side. Spintech's sound awesome but are loud. There is some drone in the car with them once you dump the cats and get headers. At the end of the day though they sound pretty amazing. Running under the axle back there is actually pretty common. qwkgto has his under the axle with turbo's on there without any clearance issues.

    Orion, I think you are the ONLY one here, other than myself, who likes the single exit on the 04.

    I don't mind the same side exit at all. I think it's a little more unique than the split backs. Everybody and their brother have split back duals.....the 04's are a little unique that way.

    personally I think the spilt end exhaust looks meaner. When I had the single side version it was always in the back of my mind knowing deep down inside I really wanted the split end version. Its all peronsal choice though. The single side doesnt look bad.I bought a jba 05-06 catback and they also did the cut out.

    ^^ nice job. Most of the 05-06 setups I have seen had the pass pipe hanging lower than the driver side stock. You have a nice setup.
