Most people think its cheaper and easier to just go and buy a TII. I personally want to have both N/a and TII not just TII or N/a.

 

I use the single side N1 catback but I also have no cat and run a 3" downpipe. It's not loud at all untill you romp on it. It has a nice sound at idle, doesn't resonate down the highway nor does it get annoyingly loud inside the car when on the gas,. It does make people turn to look when your on the gas though, sounds really good outside the car but it can be heard for several blocks when you romp it. Not tinnie or shrill, a nice growl though.
