I will let the specs do the talking for my mufflers.

Not trying to start a muffler war but needed to defend my choice.

 

 

They are still a chambered muffler............going to a straight through will get you another couple of hp at higher rpm. With you having a low reving MFI enbgine, it isn't as big of a deal, but those mufflers would NOT be optimal on anything that revs past 5K with any authority.

 

BTW.............Summit could claim that their mufflers make 600hp more than a competitors...........that doesn't mean it's true. Manufacturers lie ALL the time about power gains (only a select few actually provide dyno charts and REAL power gains.........AEM and Injen come to mind........and Random Technologies makes an attempt).
