In our initial testing, of our Catback exhaust, we found greatsolidgains of 10 Wheel HP and 10 ft-lbs of torque.  While 10 WHP is verynoticeable, the most noticeable thing you will find is that theturbospools quicker providing roughly 200RPM quicker spool.  This quickerspool means more low end power!  Something you might not noticeissound. It is very important to us and everyone to make the exhaust makepower, but noise/tone is the next thing people are concerned with.Ournew 3" system is designed to be very very mellow and appease all typesof customers. No loud "farty" Honda sounds here!

NOW ALTA Takes it one step further and makes an entirely new lookto an already great product! With the addition of a thermal Powdercoatin a matte black finish, you can have the extra power and hide it too!

304SS is known to be the standard in all high quality exhausts systems. 304SS provides high corrosion resistance, and excellent for extreme heat up to 1600 degrees. This is also what all of our Mufflersare made ofinside and out. Where many other manufactures use 409SS(will rust overtime and is what most OEMS use) the added expense ofthe 304SS is wellworth the long lasting high polish, and long termdurability.
