No mufflers = loss of torque?

What do you guys think, do you lose torque with no mufflers but you still have all 3 cats in place?

I didn't really notice any difference. I guess it depends on the sensitivity of the butt dyno, but all I noticed was it felt faster at high rpm, but that could also just be because it sounds faster, it must be faster, right?

Actually eliminating the rear mufflers does decrease torque a bit, but will give you a few extra HP on the top end. Most guys will add single or double X-pipes in order to keep the back pressure (torque) down low, while gaining the HP up top.

I don't see how doing anything with the stock manifolds and cats in place would change the torque. The stock manifolds and cats will have way more restriction than any muffler at the rear of the car.

funny, i removed the back half off of my exhaust (gen2's are flanged midship) one day i was bored after work so i took it off. needless to say it went back to stock the next day, i didnt like how it sounded too buzzy to me, and i like loud exhaust, and if felt like it was lacking power. i agree with driller, but it did feel like i had to accelerate harder to get moving

Removing the mufflers won't do much of anything either way.

And you do not lose torque with a bigger exhaust... you lose it with a too big exhaust because of poor velocity and scavenging - which are commonly mistaken for backpressure.

I didn't notice anything...

No issues when I removed my rear mufflers & resonator.
