Got a request today for pic of Magnaflow CARB Header.

Notice primaries not pinched in Magnaflow above, quite a bit better than STOCK unit below.

I saw the problem w/ the stock header as it was included w/ my new car. Someone called that "Ok".
My car does not have a rear bar installed, but I have the stock one w/o the mounting brackets. Does anyone have the brackets sitting around so I can try the stock bar at Qualcomm. I am thinking I can soak up the bumps w/ less compression and still handle body roll w/ a bar, or stiffer bar setting.
Thanks.

Hello Brian, I am really interested in the new Helmholtz race muffler but i am curious about a few things. Before this was announced i was thinking about getting the street single and having that as my only exhaust change. I was worried about drone though and just have not got myself to pull the trigger.

How much louder is the Helmoltz race over the normal Race single and Street single. I seem to remember the Helmholtz midpipe increases the overall sound output while cutting down on the "drone range". If this new muffler is indeed louder than the normal race single, that would be too much for me.

Also, is there a plan to make a Helmholtz Street single muffler? I think that would be a great solution for a DD with no other exhaust changes planned. BUT this would hinge on how loud the Helmholtz race is i guess.

The Helmholtz Race still includes the same fiberglass resonator as the standard Race, so result is more mild than Race and less drone than Street Single, but more volume than Street Single. We really made that Helmholtz Race for guys using otherwise stock NC, it's the MOST fun you can have in my experience with NC exhaust on otherwise stock car. But if header going on the car then I want Helmholtz Midpipe and at least the Street Single at the back.
