Not at all, your asking all the right questions at the right time.

Look, everybody has an opinion and most are right...for them. That would include me.

My thoughts:

1. Most people don't realize how LOUD cat backs are.
2.Most people don't realize how MUCH LOUDER they are with headers. You really must want a L-O-U-D car with both. I am constantly reminded of the damage being done when we go out to lunch as a group and the header crowd sit there yelling at the waitress because they can't even hear their own voices. Seriously, headers are VERY LOUD. So, I caution you. Big Bucks...modest improvements. BIG NOISE....big hearing damage. At a bare minimum you MUST ride in a Viper with JUST the catback you are considering and then with BOTH the cat backs and the headers. What are you doing with your cats? Let me guess....

3. Rockers...not expensive, you do not need Jezels. A set of Harland Sharps will do you just fine. It was one of the VERY few modifications that I did on my stock Viper that I immediately felt on the first get up and go. I did them before I did a Roe and I did them at the advice of everybody. Blower? Rockers!. 'Nuff said. You will thank me, your engine will thank you.

Oh yea, your smooth tubes and the filters are great! Your done.
