No felt gain for me. I actually felt better throttle response with the stock manifolds. Do a search but a lot of discussion has been made about heat loss due to the surface area of long tubes compared to stock manifolds as well as material of the two attributing to heat loss. I hated the ground clearance issues and love it so much better with the stock manifolds.

Loose power... do a search on this, we have had some very indepth conversations about this. Thermodynamics says <ding> more surface area increases heat dissipation reducing the overall effectiveness of the turbo.

(there are some exceptions to this... but it requires extencive coating or wrapping... again.. do a search on the subject)

This is why I sold my LT's and bought some "decent" flowing manifolds. Cast iron vs cheap thin-*** headers. Which one do you think would retain more heat energy, which would keep the molecules excited and propel the turbine? =)

good question i just bought a sts kit and have longtubes and wanted to see if they will work if they are wrapped really good.

I switched from LT back to stock manifolds. Throttle response was a little better. Spool time was also reduced. With the LT the wide band would jump about half a point up and down at idle and under normal driving. With the stock manifolds the wideband varies .1 up and down.

Long tubes will work, but will be laggy. I will be putting my stock manifolds back on as soon as I can get to it.

what about fully ceramic coated hotside piping with long tubes? Better than manifolds?

No, they're still thin gauge, whatever way you look at it, and a lot more volume.

if $ is no issue im guessing stock ported manifolds coated, wrapped, and painted (for moisture) along with the rest of the exhaust to help spool.

I had coated shortys with rear twins and 2.5" pipes. if i had to do it over, I'd use the ugly stock manifolds and 2.25" wrapped pipes. Heep the heat and velocity and your a few hundred RPm and horses to the good.

LOL! I’m actually in the process RIGHT NOW of removing my LG long tubes… For a minute there, I was getting second thoughts and decided to come in and do a search! Hahaha… OK, back to it!

Some time in the next week I’ll make a thread with side by side comparisons...
