ok i'm stuck between the flowmaster 40 the delta flow 40 and the new super flow 40. i'm not sure which one is right for me it going on my 05 f150
now i'm the type that likes straight pipes or glasspack sound on my 68 and 78 car, truck but i don't want that sound coming out of my nice new truck. i want that nice rumble coming down the road. I downloaded some files but still not sure.
I have the delta flow 40 and I love it. If I was going to do it over again, I think I'd try the super 40. I think it sounds more like you're talking about. Neither of those resonates much in the cab.
I just had the regular 40's put on my 71 with a 302 and tube headers I would stay away from those if you want to keep the loud sound down alittle. But the guy did tell me they put a set of them on a chevy that was pulling out it had cats still on and it didn't seem very loud at all not even close to the way mine sounds. hope that helps
