Duel 3.5 inch exhaust???

[RightRyan]

I'd like to go duel 3.5 inch exhaust on my 94 300zxTT. I at 484whp at the moment, untuned. GT525 Turbo's (54mm), 740cc injectors, JWT race cams, front mount, 2.5 in downpipes, head ported and polished and so on. Is there a downside to running duel 3.5 inch??? I'd like to eliminate back pressure. I'll have the AEM standalone shortly to do a full tune

Any feedback would be much appreciated

Dual 3" exhaust is what you want. Contact SpecialtyZ.com, they have everything you need.

Just so you know, you may make the same or less power once tuned, if the tuner is smart and using knock detection.
