Need actual user input/opinion Mac/VH

[Madmax]

I am building a 1981 GS650GL into a cafe' bike. I can get a 4to1 Mac pipe or I have read the thread that states a V&H pipe for a 550 will work with gaskets. I would like to hear from anyone that has actual use of either of these solutions. My 750 got a good boost in mid/top range with V&H. I appreciate any info you might have. Thanks in advance.

Power gain with a pipe is kind of eh...where you gain the most is the weight loss big time.

I don't run either (I run Kerker) but you might also ask about quality of one brand vs. another.

Go with the V&H
Better overall quality.
Gaskets? You always use exhaust gaskets in the head.

I have had Mac, V&H, Kerker. I took off the Mac and sold it, the Kerker and V&H are much better.
