unless you plan on adding a supercharger the long tubes will do nothing but lighten your wallet! Now the pro-chamber that will give you power! imho flows = loud , no power. The combo of pro-chamber and flows from what ive heard its realy loud, but that is what some are after.......
long tubes will do nothing but lighten your wallet.
the mechanic that did part of my exhaust on my first mustang had me put on a mac catback and mac prochamber, he said it would add bout 30-35 RWHP by the way it sounded great u wont regret it
what?, are you serious?....
well I subscribe to 5.0 mustang mag and I pay very close attention to the exh stuff in the articles. All the dyno test on long tubes lost 3-5 hp across the band over stock manifold untill bout 5,300 rpm then gained about 2-3 hp? So yes Im serious! on our cars spinning the eng over 5,500 rpm is a waste , the hp starts to drop dramaticaly at 5,200-5,500 anyway . mine wont spinn to 9,000? why would i want to pay 200-700 bucks for 2-3 hp from 5,200-6,000 rpm?!
