I picked up my Viper two weeks ago and already I've started doing some work on it. I've hard wired a battery tender to the car and the next thing I want to address is the exhaust.
The car already has hennessey headers with stock cats, stock resonator and then rear muffler delete. The car sounds good, but I can start to see potential discoloration on the side sills and I want to avoid anything further. As such, I'm looking to remove the cats but don't know if I should remove the resonator too. I took off the sill today to see what it looked like:
I live in California, so I need to have a cat when I go in for smog. As such, I'm wanting a setup where I can easily switch between cat/catless. It looks as though the section from the cat to the resonator is welded together and it connected to the exhaust by clamps. As such, here are the options I'm thinking:
1. Option 1: Remove both cat and resonator section and replace with straight pipe. I'm assuming this will get rid of the heat but don't know if this will be too loud as it'll just be straight pipes all the way through (no cat, resonator, muffler)
2. Option 2: Cut out the cat and use clamps to clamp in a straight pipe. Prepare the cat that was just cut out to be able to be clamped in. Sooner or later I would buy the HF cat and use those to clamp in for smog instead of the stock cat. This will again remove the cat and a good amount of heat. I don't know how much heat the resonator contains (if any). The exhaust will be straight pipe other than the stock resonator. Will likely still be loud but more tame than option 1.
3. Option 3: You make the suggestion
Regardless, I will be picking up the Speedtactics side sill vents as well to help airflow while the car is in motion.
Here is how the car sounds now
