there is a catback system for sale where i live very cheep but the guy says its for a 06+ would i be able to modify some stuff easaly and get that thing to fit in my 01 s2000, and what would need to be done?

 

What brand and model exhaust? Many work on all years.

 

Depending on the exhaust, it said that the 06-UP have a different exhaust tunnel trail. Some ill work, some will not unless modification will be made.

IE. 01-05 J's Racing Exhaust will not work on an 06-UP due to its trail unless modified

 

its a n1 style Invidia Titanium Tip Catback Exhaust System

 

I'm not sure if this changes by the version (there are 3 i think) but it should work on all years...
