    Do I really Need an X-Pipe

    I am thinking about going from Pace setters, & SLP loudmouth setup to some type of true dual. And i was wondering if i Really needed the X-Pipe that almost everyone seems to do.

    also what is the purpose/benefit of this. I'm new to this and YES i did a search but couldn't find the information after reading for about 3 hours or more.

    I plan to lower my car with strano springs and was wondering what you recommended. My LM resonator seems to hand down a little and drug twice today I believe the cars ride height is stock.

    Thanks

    If your running duals, run the x-pipe. It equalizes the pressure beween the exhaust flow so the engine runs more efficient. If your gonna run any pipes larger than 2 1/2 inches, I'd strongly reconsider lowering your car. My ground clearance sucks with the 3 inch pipes I have and my car is stock height.

    i THINK it's stock I'm fine with 2.5" pipes as long as it's true dual or i can do a cut out. The car has been previously molested...err. owned that is. lot of things I don't like but it's mine now and time to make it right.

    Oh, and I forgot to add, your gonna have to run at most 2 1/2 inch pipes (and that's still an extremely tight fit) if your gonna have the exhaust run over the rear axle and out the back.

    Maybe a strange question, but could i put a stock exhaust on without the cats with my pacesetters on there. with cutouts? I think that might be cheapest and best for me at this point.

    You'll be able to do that. You'll just need to buy a Y-pipe and an O2 dummy sensor or delete the 02 from the computer when or if you decide to tune it.

    Alot of guys will just run headers, an ORY with the stock catback. Then just have dual cutout in the ORY.
