How many hp do I gain if I remove catalitic converters?
I suppose that I need MIL eliminators.

Thanks in advance for your answers.

Probably a few, but I've yet to see a dyno chart with no changes other than just a midpipe swap.

I'm about to sell my coated Mac O/R H pipe (no cats), PM me if you're interested.

I've seen magazine reviews that claim 7-10 rwhp from midpipe swaps.

You won't gain more than 1-2 HP by removing the cats. Actually, you might loose torque. If you want your stang to be really loud, remove them. If not, leave them on there.

yeh you will probably gain a few up top, but nothing spectacular. if i had the cash, i would have put a catted pipe on there. no need to pollute the air even more for a few hp

I noticed a loss in torque and nothing to mention in the HP department. It's a lot louder though

This is true for the highflo cats vs off-road but you'll probably gain 7-10hp going from the stock midpipe to an off-road X.

I took the cats off my stock h-pipe the car seems to run alot better..I got it done really cheap so cant beat it.But I will soon have a differnt mid pipe on my car but for now I am happy..I really dont see how you would lose alot of power to me going with a aftermarket mid pipe you would lose some down low becouse the lose of backpersure..In less the car is got alot of mods..
