Title: Mac pipe Post by hotrod on 08/19/17 at 11:43:37 Will we ever know how well a Mac exhaust works  ?  How loud ?  Best carb set-up ?

Title: Re: Mac pipe Post by SALB on 08/19/17 at 11:56:00 Which version are you asking about?

Title: Re: Mac pipe Post by LANCER on 08/19/17 at 15:10:09 I posted my impression of the MAC system a while back. Basically, the 1.75" ID header is too large for even a modified LS650. They need to bring it down to a 1.6" ID for modified and 1.5"ID for stock engines. The muffler does have a pretty good sound and works well. The muffler is worth buying but not the header.  A stock header works better then theirs.  The S40 I tested it on has a stock carb that has been jetted and a Stage 2 camshaft, and it actually lost power with the MAC system.
