    thats what I was trying to find out. I know that Borla makes a Y Pipe system. I was woundering if they make a duals system? Thats what I was trying to find out from the other gentleman...

    I got my Bassani setup from here: http://www.lmperformance.com/5796/1.html (They're a site sponsor). I don't have any pics of mine, but I have a video I made right after install when the stock manifolds and cats were still on here: http://s217.photobucket.com/albums/c...nt=Bassani.flv Mrr23 has pics of his install here: http://www.stealthram.com/bassanidualexhaust.htm with performance increases listed in the lower right side of the page. As you can see, the duals outperformed cutouts too. With the Bassani duals, I gained .15 in the quarter on street tires with traction problems. Would expect that my gains would have exceeded .2 had I been able to get it all to the pavement, but I spun on takeoff through 40mph. Considering it takes about 10HP to drop about a tenth, I estimate I gained 20rwhp from just a catback on stock manifolds, cats, and tune. That's also right after installation without giving the PCM time to retune itself for optimal fuel mix...

    i like the duals set up but not the mufflers, I will have to look into see if they just sell the x pipe cause I would be down with that, just not the muffler...

    2001 WS6

    I have a 01 WS6 (automatic) and Iam getting 419hp & 433ftlb of torque at the wheels. Ive got paces setters long tube headers, (no cats) SLP air box, 3 inch y pipe, cam change, hooker muffler and a 9inch 3000-3500 stall. It was also dyno tuned. After all was said and done my car runs 11.80s 1/4 at 115mph. Now Ive got to change the carrier in the rear end, M/T tires , drag strip on a good day, and all that torque made the car run good but the weak leak is the rear end. I forgot I also did T/B coolant bypass, no baffles in the Ram Air hood, MSD wires, & ngk plugs.

    About $2500.00-3000.00 in parts and 300.00 in dyno time & tuning. I did all the work myself. I love to work on the car. GM did a great job when they made the LS motor, its easy to work on and the bottom end is tough. Mine turns 6500rpm with no trouble. I also use royal purple oil in the motor and trans. I dont know but I think it makes a diff. When I changed the cam I also had to change valve spring and push rods
