[QUOTE="DeepImpact, post: 15924726, member: 190685"] I love the sound of the GT500’s. I have the Lethal OTA’s ready to go on along with the JBA H pipe. I will run it first with the cats. I am going to guess that half of the mid pipe gains are from the fact that the stock pipe tapers way down to like 2 1/4” after the cats. Eliminating that pinch point has to help. It starts out at 3” and end’s 2.75”, but it is much smaller in the center section. If this doesn’t put me where I want to be then I’ll add the front portion of the H that eliminates the cats. Still need a tune and drag tires. Hoping all of this will net me 11.60 @ 116mph. That is a full second away from my bone stock baseline, but that was on the OEM 4 year old Pirelli’s and crossing the line in the limiter at 110mph. If the AED tune can’t get me there with these few mods, then maybe a CAI and 18 intake manifold. Sent from my iPhone using svtperformance.com [/QUOTE]
