MUFFLER OPINIONS

Thanks. They said the Street Pro were louder at idle than Race. But were less loud under power. I hope tgats the case. Dougs Headers 10.88 to 1 422 Aluiminum Headed 240/252 @50 ground on 110* 560/570 solid.
It's a,big step down from my current big compression motor.
I just wanted muffs that fit the Pypes pipes so ordered that.
Note)
I have heard both Summit and Jegs turbo pipe muff kits and they were cheaper fit well and sounded good.
