What if we already have downpipes installed.
Surely you can tune it regardless of what brands we have used.
Yeah we can but if you had say an Ebay special, a Viezu or a first gen (twin pipe)APR down pipe the task becomes harder due to their poor design. This means extra cost to the owner for the same result and or chance of lower outputs.

New CTS,APR,42DD (shift cable burner),HPA, Milltek with crap inlet and a few other name brand ones are all OK

So I pretty much include this just to make the process easier and the results repeatable.
