I was thinking lately for experimenting a little around on the exhaust system of my Gen4 SRT.
I got an idea on this vid on youtube
YouTube - Dodge Viper SRT 10 exhaust sound (MUST hear!!!)
I could see on that video that that bypass system would not free the resonators and the catalytic converters.
What came up is to use some cheap wastegates off Ebay (for around $100 each) with 2-1/2" openning, and place them somewhere before the cats.
Apart from the noise, I suppose that will make some power improvement in combination with the Mopar PCM.
Here is the wastegate.
Here is the elbow pipe that I had to weld and cut an etension for reaching the correct length.
Here is also how it is planned to be welded
Another picture also of the planning with the wastegate.
As about the control of the wastegate valve, I am thinking of stealing some vacuum off the power brake booster tank and make the management when in WOT and at some certain RPMs.
I will keep updated for anything new that will come up.
I am open to comments and any advices.
