Could you explain why resonated test pipes will eliminate rasp? Is this their purpose? Do resonated test pipes work as well as resonated HFCs? What brands should I consider?
So to maximize power and minimize rasp, my order of preference should be:
1) Resonated test pipes (less rasp, more power?)
2) Resonated HFCs (less rasp, no difference in power?)
3) Different HFCs (maintain power, hope for less rasp)
4) OEM cats (least rasp/least power/quietest)
5) Test pipes (most power/most rasp/loudest)
?
I look forward to your advice! Thanks in advance...
Marcus
