Downpipe & Exhaust Fitment Thread?

[Highboost145]

Is there any downpipe and exhaust fitment combination thread? I'm looking to get an Acive Autowerke DP and HKS Titanium exhaust but I have a feeling they won't fit due to difference in pipe sizes and tapering. Any guidance would be much appreciated.

Unless otherwise explicitly noted, every downpipe and every catback necks down to the stock 3.18” diameter. It’s up to you to modify the middle, again unless explicitly noted, to be a larger diameter if desired.

AA downpipe by default is 3.18” but also has a cut point to be 3.5” or a cut point to be 4”.

I actually have an appointment for this Thursday to modify my downpipe and catback to get rid of the neck down and be a full 3.5”

unfortunately, this is what we all gotta do.

The connection points will fit but the diameter of piping is different like you said.

AA downpipe mates to stock and aftermarket exhausts. HKS mates to stock or aftmarket downpipes.

We have both in stock.
