    Anybody tried this exhaust out? What are the pro's and con's? It has Dynomax Bullet mufflers with turndowns. I wish it was stainless.

    My buddy has a true dual setup on his 02 SS except he has 1 chamber flowmasters and it look slike shit from behind. I would not waste my money unless you wanna drag it off. His car isn't lowered and it it will scrub.

    That exhaust should be fine... any x-pipe with a good merge will work.

    I like that black trim hood with the black trim on the back Big D. You thought about getting those black trim headlights for that SS?

    Do you guys think I would make more power if I get rid of the SLP Y and Hooker CB? It already scrubs with that setup, and my car isn't lowered.

    What part of your car is dragging? My car isn't lowered either. I have the SLP Y and have never heard it hit anything, speedbumps included. My front air dam rubs going into and out of some driveways, but that can be helped sometimes by a different approach angle.

    If you take your time mounting a dual setup, it should leave a lot more than 1" of clearance. That guy was also taking about a car that had been lowered about 1.3 " The second set of photos posted in response should give you a better idea.

    As long as you aren'r four-wheeling your Z, a good fitting exhaust shouldn't rub at the stock ride height.

    And to answer your last question, yes you should make more power with the dual setup over the SLP Y and a catback. You will also have a lot of cabin noise from the turndowns that exit before the rear axle. It will be very pronounced off idle.

    Mine scrubs from the collector to about a foot back on the Y-pipe. It could be prevented if there wasn't 3" between the floor pan and the top of the Y. It looks like the headers angle downward at the collector instead of going parallel with the floor pan, thus the clearance problems.

    What about exhaust problems, will the turn-downs leave carbon residue on the rear of the car? I have seen cars that are driven daily with pipes that exit under the car, and they have a black carbon powder where the wind wips under the car and around the back.

    I bought the car with the headers, Y, and catback already on it, and it looks like someone has put aftermarket shocks on it. But I don't know if they lowered it. I do know it scrubs on high speed bumps, and I do have to change entrance angles to keep it from scrubbing on steep driveways. You can see the pipes under the car from the side, easily.

    I forgot - I looked at an old PM you sent me about your long tubes dragging. I've heard nothing but bad stuff about the SLP headers - sorry to hear thats what was on there when you got it.

    I have the SLP Y that bolts in the stock location, to the stock manifolds and converters.

    TSP duals don't hang that low (1" ground clearance). I haven't even had the chance to tuck mine in yet and it still has good ground clearance. (granted I'm not lowered but there is a lot of room to tuck my exhaust up) And from what I've heard the e-bay kit isn't all that great, go for the tsp.

    Here's my car right after I got done with it, I've been too busy to play around with it and have had no motivation yet to raise it because I don't really scrape.

    Got the TSP pic, thanks 00SLPSS. Looks like plenty of clearance. Approximately how RWHP do you think its worth to swap over the the dual setup?

    Also with my exhaust I have about 1.5" to 2" to tuck more up. As far as the dual setups go a user on ls1tech by the name of mrr23 did bassani true duals on his wife's car and picked up 13rwhp or so (can't remember exactly).
