Hi after some help from people that have done testing etc with headers …. Currently have a L98 with cam etc with 310 rwk….. exhaust currently a 3” system with Magna flow mufflers on the rear and VF HSV headers …. I’m getting a Harrop 2300 fdfi fitted soon and am in a dilemma on which size manta headers I’m going to put on …. Everyone I’ve talked to including performance workshops and other people that have supercharges recommend to go with the 1 7/8” over the 1 3/4 “ but the very well renowned and trusted workshop fitting the charger are saying go the 1 3/4 “ …. Now what I’m worried about is if I did go the 1 7/8 will it be considerably louder than the 1 3/4 “ ? I have also heard you loose a little power down low with the 1 7/8” headers but seeing though it’s going to be charged if that will be a problem anyway ? And also I was thinking as I’m running 3.7 gears and manual that Loosing a little down low may help with not getting to much wheel spin and may be a better choice …. So ultimately my main concern is if the 1 7/8” headers are going to be to loud or much louder than the 1 3/4 “ …… any advice or experience to help point in the right direction will be appreciated
