Mods in signature. As it says I am running AFR 205's 224/228/114 comp cam Pacesetter LT with Texas speed Catted Y goin into 3in 4in Merge collecter into SLP LM Exhaust. I dynoed 427rwhp and 398TQ My question is should I get electrict cutouts 1 or 2 how many? DO I need to get rid of the Pacesetters Is that holding me back on power . I want the maximum horsepower from my setup. I heard QTP or ARH headers are the best for power. What do you guys recommend. Should I leave everything alone. Please opinion Thanks.

PS I wanna keep cats weather I keep these or go something else Thanks

Are your numbers off a mustang dyno or a dynojet or dyno dynamatic? It seems to me you look like your numbers are right and I don't think there's nothing you left on the table power wise and if you do upgrade if you do it yourself you may spend $400 (maybe 5 to 10 hp if that) for the headers and if someone else install them then you will have to pay for labor. Be personally I think it would be a waste of money but it ain't my money it's yours.

Actually I didn't notice it a first but if you want more power then you may need to step up with more of a cam. If you can do it yourself but if you want more power I would say maybe more of a cam would do it cause you have everything there. My cam is similar to a VRX3. An you have a ported fast 92/92 which I just have an LS6 intake.

Thanks yea it was on a dyno jet in 85 degree weather 90% humidity in Fla. Are your numbers SAE or STD?

Well as far as exhaust goes I think I've found one of the best flowing non-true dual setups, as I'm making more power than most people are with the same mods that use an ORY, and I have cats.

Kooks long tube headers (1 3/4"), matching Kooks y-pipe with high flow cats, and Borla exhaust with the wide open plate. For having that, an intake, and a non-dyno tune, I'm making 360 rwhp and 375 ft lbs. I credit most to the Kooks headers and y-pipe, I gained a HUGE amount of power when I added those. I've not had experience with ARH headers but I've heard they flow very well, up there with Kooks. Eventually when I get AFR 205's, a TSP 228R, Fast 92/92, UD pulley, and injectors I'm really hoping for near 500 rwhp.

cutout won't do much on the loudmouth setup

you could go cutouts before each cat, but that's not something you'll want to run every day.

stick with what you have. if you want more power, there are other mods that will achieve it.

1 7/8 headers will add more power over your 1 5/8 Pacesetters. as far as your current setup goes, removing the cats will free up roughly 4 rwhp. other than that thats the freest flowing combo you can get with a y pipe. a cutout will do nothing

Yea for the most part everyone is right. You can't get much more free-flowing than the LM1, which is what I have also. I also have the Pacesetter longtubes, which I believe to be decent, I've always heard the Pacesetter Y sucks tho. Most people get a better flowing Y or create their own merge (heard the flowmaster merge is good).Deleting the cats wouldn't do much nor would cutouts. I ran open headers for a few days before I got my LM1 on, and let me tell you, you could hardly tell the difference in loudness lol. Spend your money on more beneficial mods.

Thanks Guys so what would you reccommend for more power a bigger cam maybe somewhere in the 230's.

cam would be the obvious upgrade

but something like gears may make a huge difference too.
