I think you would need to add a manual boost controller in the line to the wastegates so they didn't see any boost till a predetermined psi. Wastegates creep open up to the set spring level. A 5lb spring spring starts openning as soon as it sees any boost and is fully open at 5lbs.

On a related note, also add a manual boost controller to your turbo's wastegate. It will help it spool faster by not letting the wastegate see any boost until your max psi.

Hell Im 25 and I like quiet exhaust, I prefer to bbe able to hear myself think. And for those of us that tow a loud exhaust gets old real quick, so much so Im going back to a stock catback and am just going to run a cutout off the ORY.

When I first mounted the blower in 2003 I had the stock exhaust and did the following

2004 - Magnaflow Catback - OK good sound not optimized
2005 - Added Shorties - Throatier but not much better in power
2006 - PaceSetter Long tubes - Noticeable better in sound and Power
2007 - Dual 3inch with magnaflow resonators - Too Loud
2010 - Dual 3 inch with a true x crossover pipe and 2 large straight through mufflers. Surprisingly got better mileage probably due to scavaging while not in boost. The x pipe also keeps it quiet in low throttle but turns wild when you turn it up. Ivre read somewhere that the tru x crossover reduces noise by 8 db over an H pipe. Also engine winds up much quicker.

Here's a Clip of the latest at 60% throttle - No drone in cabin
