X pipe with or without cats...
I have Borla after cat exhaust system on my 03 Cobra, and want to get the X pipe with/without cat exhaust portion.
I was hoping I could get some information and hopefully some opinions on the following questions:
1.) Is the without cats (off road) X pipe exhaust louder than the with cats system?
2.) Can the without cats (off road) X pipe system be driven on the street legally?
3.) What is the most preferred X pipe brand? I'm leaning toward SLP and I may want to eventually get headers, so I want something that will allow that later on.
4.) Is it safe to say any X pipe brand should bolt up to the Borla after cat system?
5.) What other accessories will I need, that may not come with just the X pipe exhaust, such as oxygen sensors extensions?
6.) Will the oxygen sensors need anything to get the max performance from the new exhaust?
Sorry for so many questions, any help is greatly appreciated.
