I have the "cheastpest" Mbrp..not gonna lie I had to do some mods.
Wasint much but I had to weld one of the pipes together cuz the fitting was off(made a very, very, very unpleasant noise because of it & less drone after welded) did the diy sympo delete(made a noticeable difference in the drone...in a good way like less drones)Also had to reposition/smashed in some of the heat shields under the car so it's not touching/rubbing. And replaced the 2 dp bolts to longer ones cuz the factory ones were really short and was giving me a headache....
because of the little mods I did(which ain't shit really lol) I'm very happy with the exhaust now. Sounds amazing. Spools really loud. It pops and crackle and scares me sometimes when I'm not excepting a loud backfire but sometimes it sounds like a damn gunshot. Also sometimes tends to do multiple backfire.
With my intake,bov, downpipe, and the exhaust...my car def. sounds a lot faster then it really is lol
Oh and to get a idea of how loud the backfire can be...I dropped my friend of and about 2 blocks down I had to gun the yellow light turning red, so I did and pretty much my friend said that it was so loud he got scared and thought I pulled up next to him lol but I was like 3-4 blocks down by then lol
Hope this helps...this was all that I can think of to possibly help you get what you want.
Oh and to top it off...the stutututu noise before the backfires or slight pop n crackles really makes it sounds like a tuner car. Lol
Happy late New Years
