Sts - Wrapped Exhaust -- Inside!!!!!
Sts - Wrapped Exhaust -- Inside!!!!! about 2-3 weeks ago there was a thread about wrapping your exhaust on an STS car to get more hot exhaust to the turbo, i was one of the people who did not grasp the concept that hotter exhaust would make a difference. I WAS WRONG!!! i wrapped my exhaust last night and my car is totally different now, it boosts much quicker and pulls harder, i cant wait until i get it to the track to verify what my butt tells me.

i bought header wrap from advance auto and wrapped my entire exhaust from the header collectors back to the turbo. i didnt take pictures , that will have to be another day. it took 2 50' x 2" rolls.
yeah I did the same. What a difference it makes! I actually bought 2 rolls and need to buy another roll to finish just have been to lazy. The reason it helps is because hot air is more dense they say.

good to know guys, i was keeping my truck running the entire time in the staging lanes for fear of losing heat in the exhaust. I t should help with cold starts also, just seems sometimes after the truck sits it takes a short trip down the road to get full advantage of the turbo.anybody else have this prob?

actually cooler air is more dense, hot air takes up more volume, so keeping the heat in the exhaust pipe will effectively take less effort from the motor to fill that pipe and it spools the turbo, you guys would be suprised to feel a front mounted turbo with wrapped headers 
I have a 67mm hitting full boost by 2800 and it starts to spool at 2k.
