I see two options: one is to grab a set of Motordyne Art Pipes as they have less rasp than even HFCs (decreased volume compared to TPs), or a set of resonated test pipes. However, nothing will match the volume of the test pipes. It is a tradeoff: you get more volume from test pipes due to the lack of muffling or restriction but conversely this design allows for rasp.
Sounds like resonated test pipes are your best bet while maintaining the performance of test pipes and decreasing rasp without affecting volume as significantly as HFCs or Art pipes.
