1 or 2 cutouts

**brian_king25** · 04-08-2011, 07:25 PM

Just like it said! Should I use 1 or 2 cutouts on a F1A procharged 402 running 15 to 18 lbs of boost.

I was thinking 1 just after the y pipe or 2 after the headers

ANY THOUGHTS!

2 after the headers makes more sense to me.

when i got mine, i wanted to do 2 before the y pipe.. but i had no budget for a second cutout so i went for one on the I pipe, if u have the budget i would go for two.. but one is loud enough.

I prefer to use 2 after the headers.

I think with 2 there's to much back pressure loss. You will notice a loss in torque at lower RPMs

I never had that issue. I open them up at the track and generally see a small gain in ET and MPH.

I think two definitely sounds better. What size did cut outouts did you use?I never really close mine unless I'm going through a nieborhood at odd hours. I love listening to my car accelerate. It's going to get me another ticket someday.
