Its definetely more powerful at higher RPM's though.

BTW I dont know how anyone can feel 5-10hp in a 350+rwhp car, thats 1.5 to a 3% gain, its all in their heads. Theres no way you can feel a 5-10hp difference.

Its all in your head. **** my car feels like it picks up power after I wash and wax it.

Yea I bet this sounds 100X better in person, same thing when I took video of my exhaust, it doesn't even sound similar lol. But it still sounds great in your videos so it must be AWESOME in person!

I finally got some vids of my setup in sig. Its close to what it really is. It makes it sound better than it is b/c it doesn't record the fluttery, rasp, popping sound.
I'm hoping to get my 1 chamber duals put on this friday. I'm definately getting a lot of video of it!!! Pics too.

One of the reasons people feel like they dropped low end torque when getting LT's. The sound and extra vibration overloads the senses.

For all of you..
It is not in my head that i gained low end TQ... My buddy that has a 2002 Z.. Kooks LTs + Custom 3" O/R H + 1 chambers dumped, drove my car when i had my QTP LTs + MagnaFlow 3" O/R X pipe + MagnaPacks muffs.. he said that driving the 2 cars is night and day difference.. and vise versa i drove his car and could feel a difference...
i will leave it at that

thats not good enough
a real torque seat of the pants difference is comparing lowspeed driving rpm of a singleplane carb intake vs a dual plane one .
fwiw your car had more backpressure then most X setups because you have it run out the back . If I was you I get those crimped bends replaced with manderal ones , their pretty cheap and will free up some lost power .I can find a dyno graph if you think im bullshittin.

So...I'm not on here to argue with anyone over dyno #'s or anything like that (especially since I don't have any charts to actually compare). I will say, there felt like a fairly big difference in low-mid range torque with my set-up over his old one (stock mani's, no cats, 3" X, Magnaflows). His car felt noticeably softer down low. Like him, I'll leave it at that. Same thing when I ditched my highflow cats, 3" Y-pipe, & 3" cat-back for my current set-up. The car felt much more responsive and torquey down low (it took less throttle to roast the tires, pin me to the back of my seat, etc.). Literally felt like I switched from 3.42's to 3.73's in the rear.
Again, I have no idea the true #'s and how the X vs H actually compare down low (nor do I really care). For someone who's had two LS1's, driven several, & rode in many more, this is just my honest opinion. But regardless, I absolutely LOVE my 3" true duals and would never, ever go back to a Y-pipe set-up.

Anyway, I'm his friend with the stock-internal '02 that has Kooks LT's, no cats, 3" H-pipe, & two Flowmaster 1-chambers dumped before the axle. Only other modification on my ride is a Direct-Flo lid.

Again, it almost felt as if I changed out my gears (that's how much stronger it feels now as compared to my old "single" exhaust set-up). Maybe it's not as much of a difference as I'm letting on, but it sure feels it. Granted, this was going from a Y to an H...
