Although they look very nice, I dont think I will buy another set of headers for now..!! And the Supersprint you can only use with their cats and muffler I think?

I was told by super sprint you need to get the complete kit unless of course you make your own exhaust to march up to their headers.

Nizer

this is true

Yup, rounded up to the next whole number its 25 rwhp on that dyno. Kick ***, did it improve the sound much - directed at O.P..

I would say a tune would be mandatory with so many modifications. That if it hasn't been done injector cleaner and a clean-up of the throttle body.

How much more does the Akrapovc cost than the Sharkwerks solution. And I imagine it weighs less too!

From a sound perspective, there is ZERO drone. This thing is track exhaust loud when WOT, yet bypass quiet when just cruising around. The best way to describe it is imagine being able to turn the volume up on the bypass. At WOT, the sound is a very clean wale, much cleaner sounding than the track exhaust which i thought was a little muddy. You can hear the header/bypass setup here

Only thing is I don't like how quiet it is when the valves are closed. I have now unplugged the valve and sound is much better. It's just that if I unplug it, the might as well get rid of the heavy side mufflers... Will see how "sharky headers/cats + akra sports cup" sound compared to now (sharky headers/cats + oem side mufflers + sharky bypass) when my akra side pipes arrive in... 6 weeks

I have run it unplugged from day 1 and am very happy with it. Its nice though to have the option to utilize the side mufflers if doing a very long road trip.

But if you dont want the side mufflers and want it loud, why spend the money on the Akra stuff when you could just get the side bypass pipes and M&M muffler. Or, just get side muffler bypass pipes like these and use your sharky rear bypass

Running it unplugged now but since it's unplugged, I don't see the point in carrying the extra weight anymore...

I have the akra rear muffler already but missing the side deletes.

bump for Sharky headers

anyone install these on a 3.8 yet?

I know they'll sound great but wondering if the power gains are repeatable.

Update. I installed the carnewal remote valve control so now I can just use the remote to have the valves open all the time or closed all the time Independent of the sport button. IMO was a very nice additional as I liked running unplugged all te time though there were times I wish I could quiet it down when coming home late at night or when using hands free taking a call.

P.J.S.

Sell Akra
