I seeUnless you are running a seriously pimped engine your low end will suffer. They greatly diminish the scavenging effect that is needed to promote good flow.
If I did em I was gonna do the ones that you crawl under and uncap, I wasn't gonna spend any kind of serious $ on em.Cut outs are more of a gimic than a performance mod. I never saw the point in them. Just one more thing to break.

I hope to make a 13 sec pass...What's wrong with being quiet at the track? I'd rather be quiet and fast then obnoxiously loud and slow making a 13 second pass. Don't be "that guy".
Right now the current exhaust set up is pretty basic. Stock h pipe, pre-cats removed, reg cats replaced w high flows, and forza flow mufflers.Don't fall into the back pressure trap. The h abd x pipes on our cars are there to do exactly what you described. Tune the exhaust pulses and promote scavenging. Running open header with a cut out ruins that.
GotchaCutouts are loud, but don't confuse that with sounding good.
They are really good if you want your car to sound like a 40 year old farm truck that the owner is too cheap to replace the muffler that fell off.
That old truck better not have a catatytic convertor either. But for the same grass fire reasons it needs some muffler or at least pipe the exhaust end away from the ground. A good backfire and his pasture is on fire.Cutouts are loud, but don't confuse that with sounding good.
