Two idiots who dont know WTF they are talking about fail. Educate yourself
Educate yourself part 2
There is also a lot of good info on the cobbtuning websites.

well i never ran the exhaust manifold cause whn i went to my friends dads shop to do it, he said ill cook my motor for having no back pressure. i still got a 10.85 tho. im happy with that. remember only 1/8 track

X2. You are always a jerk to people casue you think you know everything. Unfortunately you do not. And you need back pressure if you are running N/A, on turbos it doesnt matter.

backpressure in itself is bad...all around. you dont want it. what you do want is the PERFECT pipe diameter so that you get a good "suction" (scavanging (sp??)) effect. you want the fastest flowing air, back-pressure will reduce the velocity. \
think of it like sucking through a straw, use a big one and you cant get the liquid to come up easily, use one too small and you get pressure..but you dont get as much through...but if you find the exact right size for the pressure you can exert, then you can suck as much liquid as possible without any "gaps" making it loose suction....

I seriously doubt that he's gona quit, even when he doesn't understand what he is talking about. https://www.cobaltss.net/forums/showthread.php?t=174215
"One thing I do want to explain before I get too far into this is backpressure. I hear "You need backpressure to make torque." all the time. And it even comes from "tuners" as well as customers. This is flat out not true. Before I arrived into the company of true tuners I fell into the same trap myself. The reality is that backpressure is the enemy. You want to keep it as low as possible. What you do want is to keep velocity up. However doing the things that keep velocity high involves slightly more backpressure under some conditions. You want to keep the gasses moving as quickly as possible to make both good torque and top end power. The perfect exhaust system would keep the gasses moving as fast as they did coming out of the cylinder and have zero backpressure."

correct, having optimum flow means SOME (although hopefully) minimul back pressure during other rpm/ power ranges...
idealy you want 0 backpressure and all high velocity airflow with a perfect fit of air to tubing size

some kind of variable reducer at the beginning of the exhaust..hmmmm
myself, with my setup on the car i am runninga 4-2-1 header, 2.5" catless dp (to get the scavenging and velocity going) and then 3" past athat all the way out to a 2.5" muffler...it give me sound, flow, and performance
I r love my exahust...albight VERY loud lol

ok...rant time...
WHY CAN NO ONE LEARN THE DIFFERENCE BETWEEN: NO, NOW, KNOW.....OR NEW AND KNEW!!!!!!!!
LEARN TO ******* TYPE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
if it wasnt another word it would work...but you cant shorthand to another work that could fit in the sentance and expect people to get it right...
