Electronic cutouts?
Okay guys, here's the deal. I've had the Magnuson supercharger on my '99 C5 for about 5 years now. I just had a race cam installed, Spec Twin Disc clutch, 3.00 pulley, 60lb injectors and replaced a lot of my internals (oil pump, timing chain, balancer bolt, gaskets, etc).
The car is stupid fast now - couldn't be happier with it. But, I want to kick up the sound a bit so it really sounds like it could wake the dead. I'm going for the SLP Loudmouth-type of sound, but I want to be able to control how obnoxious it is. That is, if I'm going on a longer trip, I don't want that mind-numbing drone in my ear and, of course, don't wanna get pulled over and cited for the lack of mufflers.
So, I'm thinking that electronic cutouts might be the way to go, and I have two questions.
#1: Anybody else out there have any other ideas, keeping in mind that I'd ideally want to be able to control the sound, making it ungodly loud at times, but quieter at other times, and:
#2: To those who have cutouts, which ones did you buy, and from where? Do you like them?
Thanks.

You will want to place the cutouts as close as possible to the headers for the loudest and most open header like sound. I don't know how much room there is under a C5.
We are running QTP's on our 69 RS Camaro and our 64 Chevy truck. QTP also makes low profile oval cutouts. Love the sound with them open, but nice and quite on a road trip.

Does anybody have any idea what install cost would be?
I think this would be perfect for me. I can still retain the nice mellow exhaust note of my stock Ti for DD purposes, or I can open them up for when I want a nice rumble.
Thanks for any extra feedback you can give. I'm def considering ordering these.

Also, do I "need" a tune for this? I want to get a tune. But, say I installed these and a halltech stinger...could I DD it and get by? I want to send my ecm off to ECS for a tune, but if I installed these would I be safe to get by until I sent the ecm in for a tune and maximize the benefit.
