Okay, so I'm wanting to know how restrictive my exhaust system is. I currently have a 2.25 inch in/out catco cat, stock 2.25 inch piping going into a Flowmaster 80 series dual outlet muffler. The thing is, the car feels slower with the new 80 series muffler installed than when I had the stock one on! Whats up with that? Anyway, the car sounds pretty good with it and has minimal rasp. So what I'm wondering is, how resistrive is my current setup...and would I benefit very much from a 2.5 inch catback/ full exhaust? My friend has a 96 Camaro 3.8 with a 2.5 inch magnaflow catback, he claims it feels slower off the line and has noticed minimal difference. What are your opinions?

TQ is lost w/ high flow exhaust on a V6 car which can make it feel slower off the line

HP is gained at higher RPMs tho

What he said, I highly recommend to stay under 2.75" piping though unless you plan on big mods...I have 3" and is sorta killing me off the line lol, btw your exhaust is basicaly a bottle neck so to answer your Question, Yes your exhaust is restrictive.
