high compression would mean it runs hot though?? I know on my old turbo charged rs's we used to lower the compresion for more boost... but on a normal engine high compression is good and results in more hp??

i have recently modded the muffler on my 260, but i am yet to try it in some wood, hopefully this weekend!

 

I opened up the two existing holes marginally and evenly and on the little box on the inside i added a few more holes and made them a fair size, its very discreet and it sounds ace now, i feel it revs up slightly qiucker and seems like there is mroe power there across the band

 

will post up what i find!
