Does anyone know how much each of these weighs:

Comptech 4-2-1 1-piece
Greddy 4-2-1 1-piece
stock system

 

for weight reduction purposes the difference is negligible, for shipping i have no idea

 

the weight differences are so minimal...that there is no point comparing those. as far as shipping ur looking at about $20-$40 if i remember correctly

 

Thanks for the replies. I was thinking there was a bigger weight difference between the stock & aftermarket stainless header.
So, (as the original post asked)which would you recommend between the Greddy & Comptech & Edelbrock? Is there any real difference in HP gains? And, which is better quality & fit/finish?

 

the stock one is definitly heavier. its cast iron as compared to steel for aftermarket ones.

 

i had a comptech on my 01 gsr and there was a big difference in the weight of the two. i can curl the comptech with great ease but not the stock if that makes any sence. i happen to have a comptech header for sale right now by the way.....

 

right on how much? and how long have u used them for

 

like i said above the weight difference is negligible. it's not more than say 5 lbs, which is the equivilent of taking a good shit before you get int he car.

 

Why are all your options a 4-2-1? Go 4-1 with a 2.5" collector. If youre goin all motor, you're gonna want to have that bigger collector... much better than the everyday DC/stock 2.25" Do the header to tip so you can get the header/2.5" hi flow cat, 2.5" mandarel bent catback.
