Downpipes Suggestions
Looking at getting catless downpipes and midpipes for my F90 preferably in 3.5" size.
My question is does the size 3" vs 3.5" make a big difference (sound wise) ?

Keller Performance Gen 2 downpipes are 3.5 inch with standard titanium ceracote coating, other downpipes taper to under 3 inches in some places and hurt the performance, but no one talks about it, but it cost cheaper. Let me know if you have any other questions. Thank you !

Not much in the sound. More in the performance.

Im very interested in dyno results showing performance gains by going with 3.5" downpipes vs 3.0"
