Please excuse my inexperience, but my new altima is the first car I've owned that I've even thought of "enhancing". Mine is a 2.5s, with the inline 4, but I'd like to see what the best performance I can get out of it would be.
Now I fully understand the value of replacing the stock intake with a cold-air, easier breathing intake. I've searched the threads here and am aware of most of the options. Thank you all for posting your modifications, ideas, and thoughts on that subject.
But what exactly is a "cat-back" exhaust? Could it mean replacing the stock pipes and muffler from the catalytic convertor back with smoother and less restrictive alternatives? Will a less-restrictive muffler be louder (as heard in the car)? Or is it a brand name specific exhaust option? Can someone point me to a web site or catalog with more information? Is there an 02 Altima-specific version out there for purchase?
Watching Horsepower TV today, they took a fairly stock little Honda and upped it's horsepower about 13% with just a new intake and exhaust. Can I expect that same increase with new intakes and exhaust on my 2.5s?
Again, please bear with me. I'm a rooky.
