I've seen $200 Subaru downpipes look better in terms of welds and build quality than $1K BMW downpipes.


As long as you don't have crazy bends or a bunch of welding stalactites then airflow shouldn't be impeded too bad, factoring that the diameter is the same.

Sound may be different depending on resonance but I don't suspect it to be too different.
Cheers F87, do you have a recommendation for a reasonably priced decat downpipe
