I just brought my '07 SERK in for the 110 "performance upgrade" - also have to replace the heads (cracked). I'm going to have the new heads ported and polished, adding a 251 cam, 50mm throttle body, and increasing the CR a bit (already have the SERT). I currently have V&H true duals with Khrome Werks slip ons. I saw the MONSTER OVALS and fell in love with 'em. But I'm also thinking the V&H 2 into 1 (Pro Pipe BP) will get the most performance from my mods. But it doesn't look nearly as good as the MONSTER OVALS! Any clue what the performance difference will be between the pipes? If the 2 into 1 isn't going to make THAT much difference then I'm going to give the MONSTER OVALS a shot as well. Any help would be appreciated!!!!!!!!!
Thanks much!
