Any luck "derasping" F85 exhaust

[rblynn78]

Hey all, another exhaust thread here. Curious if anyone has had luck with this issue. I have a X5M, Dinan exhaust and VRSF downpipes with BM3 Stage 2 tune. OVERALL, I like it. But, there is some pretty annoying "rasp" to the exhaust at mid RPMs. Low RPMs and wide open are great.

Does anyone on here have an experience / luck / advice to get rid of the rasp on these cars? I know they made a "derapsing pipe" for E46s (yes, they were WAY raspier), but I was just wondering if anyone happened to tackle this successfully and could give me some advice. I am borderline thinking of going back to stock DPs if I cant get rid of the rasp / tin can sound. TIA

x pipe and add 2 resonators. Common solution to all F85/86 w catless downpipes.

I was trying to avoid that and went with HFC dps..

it's not clear what the problem is. but if it's rumbles, burbles and growls (so some aka rasps), then a burble deletion/down tune might do the trick. i think dinan burble tunes their exhaust. i'd love more 'rasp'. what a world we live in. what i want, you have.

those are the inequities of life

Thanks for the input. I did more research on the x-pipe and I am having it installed on Friday... hopefully that will do the truck. I sound like a Honda with a fart can exhaust right now.... ok, not that bad, but not sounding like a glorious V8 for sure

Post sound clips please

Videos before and after installing x-pipe. Dinan exhaust + RK catless dps. Without x-pipe car sounds like a cheap civic lol.

AFE has a full Downpipe back exhaust that sounds amazing but it's over $4k USD but from the clips I've heard if this exhaust, it has no rasp. I will try a custom X pipe first as I have a Dinan rear section and if that doesn't work, I will pop for the AFE

I got a Magnaflow X Pipe. Had resonators removed. Car sounds smoother but lost little bit of theatre, rapsiness is gone. Next is down pipe.

Lost a little bit of what?
