i had the same system, using the MRT h pipe it did drone, that highway noise was 100 percent drone. hell even with the s type and ford racing x it drones. I'm not sure whyBorla s-type with H pipe! I have this setup and I love it. It's loud, deep and not much rasp. No drone but you do hear it on the highway. At idle it has a very nice rumble!
I'm not going to say your wrong, and I can make it drone a little. Most of the time my driving habits don't let there be any drone. I hear the exhaust on the highway but its not rattling the car or a bad tone that will give you a headache. it puts my 5 month old boy to sleep. He loves going for rides. With any loud exhaust you will have sound cruising on the highway. Some don't like that tone of the exhaust. This is my second system and I'm very happe with this one. What system to you have now?i had the same system, using the MRT h pipe it did drone, that highway noise was 100 percent drone. hell even with the s type and ford racing x it drones. I'm not sure why
Cabin noise is not drone!i currently run an ford racing xpipe with the borla s types axel backs, it sounded better with the h pipe. But i guess the "cabin noise was too much". i wasn't sure what i was looking for .i guess it might also be the speeds your cruising at. i live in iowa at highway speeds with the 3.73 rear at 80 the car is turning over mid 2500 ish. there is quiet a bit of "cabin noise" even with the quieter x pipe
