sorry i never got back to you after i installed my system last month. ive been super busy with work and the car. its been crazy couple months for me. anyways. i put my system on first week of october and have about 1500 miles on it so far and not one bit of dissappointment at all. everytime i hit that start button its an instant smile. as for your questions on drone and sound quality. first off i'm 24 for for my the louder the better. as for in cabin driving sounds you def hear the exhaust when you have it floored ans going thru the gears hard. highway driving its not bad at all. if you arent into the throttle it's almost stock sounding just better tuned. there is a little bit of like a low bass kinda drone at 2k-3k in a higher gear like 5-6-7 while you are on the highway but thats expected for low rev in a high gear. i would type more but it said i was over the limit so if you want the rest of my review just PM me for my email and i can type u up a full one.

Hey FPenvy,
Did you receive and install your exhaust yet? I just ordered almost the identicle system that you did minus CF. So far from everything that I have heard on youtube regarding the system itselfm it's everything Im looking for! My only concern is deafening in cabin drone, which initially after reviewing reviews and videos I didnt think would be an issue. I didnt want to go resonated and then regret the system not being loud enough. So I figured I could pick your brain and get your thoughts on it as drone is somewhat subjective... If you didnt already get your system , you will undoubtedly get it before I will, as I just ordered mine at the end of September. So please respond, any info will be greatly appreciated! Can't wait to hear what you have to say...!
