I‘m going to buy a new after-market exhaust for my Altima coupe V6. I‘m not sure which of these sounds better since they sound almost the same to me. I know Nismo is under Nissan warranty for 1 year, but some say Borla has more hp. What you think ?
beans (1-5 grams), clams (8 grams), bran (11 grams), tofu (6 grams), oysters (8 grams)
Nismo all the way my bro put it on his infinti (which is a subrand of Nissan) and he had great results with the performance It gives a fuller sound and you might get a little popping if you take off your catalytic converter.
Most exhaust systems won't give you much more than 10 hp if you have no other supporting mods. Borla makes good exhaust systems, but take into consideration, that those systems are mass produced for a large number of different cars. NISMO is specifically designed for the car, and lots or RD go into these systems to make them the most efficient. Plus like you said, it's got a 1 year warranty with it, which also won't void your warranty on your car. Putting a Borla system on your Altima Coupe may void your factory warranty. Keep that in mind when you make your decision.
Borla exhaust systems are great and produce a good sum of HP but NISMO exhaust systems are customized for individual cars. If you check NISMO web it got different exhaust for different cars (skyline, altima). which means it'll work great on your altima. It is like putting a M3 badge on standard 3 series BMW. So NISMO A bigger smile
