Just a few updates on this slowly evolving project; I decided to get rid of the FLowmasters that were on the car for a set of walker turbo mufflers. The muffler shop that does all my work insisted they'd be only marginally louder than the stock mufflers that came on these cars. This car is a true daily driver, and the drone was starting to kill me. The cats are off the car, and I have an off-road MAC pro-chamber, and I know the lack of cats is also resulting in more noise. I was seeing 90+db easy with the flows, but the turbos cut about 5-8 db from the equation. After that, I decided to ditch the 4.10's. Somehow, I've ended up driving this car from AZ to CA a lot and the 4.10's just spin the engine to high for the amount of driving I'm doing. I love the 4.10's are won't get rid of them if I was consistently in one city with occasional highway driving. My decision was the 3.27's from FRPP. I would have gone with the 3.08's, but I figured the 3.27's was a decent compromise. Once the 351w is in the car, it should make up for any "seat of the pants" loss. The power is still present, but the engine is more relaxed on the highway in top gear, which was the plan.
