I have searched the forum with not much luck and not 100% sure on where to post this ? so here goes.
I am wanting to get a true dual set up for my 03 350z. Once my car is lifted up the sway bar in the rear seems to be designed for only one pipe, can 2 fit above the bar or modifications required? Also is an X pipe a good idea for dual set up and whats some recomendations on muffler with duals?
Thanks in advance

The true dual exhausts for the Z are designed with the factory sway bar in mind. You will not have to modify anything. IIRC one pipe will go above the sway and one below. At least thats how it is with my Invidia G200 TD exhaust.
This picture will give you a good visual, although it shows my car since I upgraded to progress sways:

We have a very popular 2.5" True Dual System and haven't had any installation issues with aftermarket sways so far (ie. stillen, hotchkis). Here is a link for more information:

Hope this helps,

No one answered your X-pipe question....answer: yes, an X-pipe is by far and away the best flow equalizer for an exhaust. H-pipes are pretty darn common because they are much cheaper and less precision is required to fabricate. The problem with H-pipes is that at high exhaust flow (high rpm), the emission/pressure does not have enough time at higher speed (rpm) to equalize across the 90 degree connecting pipe rendering the H-pipe virtually useless...thus you can still suffer from pressure differentials between your cylinders. The X-pipe allows a more consistent flow of the exhaust gases at lower AND higher rpm...thus resulting in higher hp & torque. It's simple fluid mechanics. When exhaust gases pass over the x-pipe, the crossing over effect aids in scavenging the combustion chambers of exhaust gases. This in turn aids in the velocity of the incoming fuel-air mixture, resulting in better performance.

I just had the Stillen TD Exhaust installed and I already have the Hotchkis sways. There were no problems and the installation required no modifications.
Stillen produces the most HP and Torque of any TD system... FYI.
