I had magnaflow cats and resonator installed today. I had been running gutted cats and no resonator. I've got flowmaster 40s. The first thing I noticed was no more ricey sound. The second thing I noticed was my boost seemed to be lower by a pound or two. I would have thought it would go up a little. I've got a 5% od pulley on it now and I have a 10% to put on it, but thought I'd ask about the lower boost before installing the 10% pulley.
I know the magnaflow parts flow good, but thought there would be a little more back pressure than the gutted cats and resonator delete, causing the boost to go up a little. Maybe I misunderstood the whole concept.
Anyway, any ideas about why the boost would be lower?
Thanks!!!
