I have an Invidia GT300 catback (Not N1 as listed wrong on their website)...N1 usually implies a racing type of tone...anyway it's the titanium tipped model bought from an Invidia dealer in CT. Nice soft, deep tone when you have a cat installed...tad bit raspy without a cat...It's about 2 months old and in not too bad of a shape..will be cleaned up and boxed this week. Pics will be up soon. I'm looking for $500 NEGOTIABLE. Btw i'm in the Navy and I'm not here to screw any1. Selling bc my SOHC took a crap on me and looking to pay off the loan still on the car. Contact number for txt/talk is 860.941.9016 anytime after 4pm..Thanks for viewing.
