I purchased a GTHAUS GTC (V.C) exhaust for my 22 Redeye Challenger and I am debating on whether or not to tap into the brake booster vacuum hose as instructed by GTHAUS. My new exhaust will bypass the OEM exhaust valves and add 2 vacuum controlled valves right before the mufflers (which are located right before the tips).
Not sure if I should use the brake booster vacuum or if I should buy a sperate 12v vacuum pump to control the new valves. I'm leaning towards buying a dedicated pump.
I'd appreciate any feedback from members that have installed vacuum controlled exhaust valves.
