Default Bad idea to wrap entire exhaust?

I'm going to wrap a downpipe in the near future and I was wondering there would be any reason not to wrap the entire exhaust while I'm at it?

I know most of these kits come with way too much wrap, so I figured I'd put it to use as long as it's safe to do the entire exhaust and not just the downpipe.

not a BAD idea, but maybe an expensive one. i am a BIG fan of wrapping/coating, but the usefulness of it pretty much ends with the downpipe. headers, up, turbo, and dp make for some QUICK spool-up

Default I agree

I wrapped my scoobysport downpipe and midpipe, mainly to quiet it down a notch. Wrap is an excellent sound insulator, if you don't run a resonator.

I will wrap most of my TXS TBE for my STI as soon as I get it. Probably back to the end of the cat eliminator pipe.

Again though... Mainly for sound dampning.

good point. i didn't think of that. but make sure you SEAL it sufficiently, or you're gonna have some corrosive sound damping there

I wrapped my header for a quicker spool. Doesn't hurt.

One thing extra I did is applied HD alum foil over the wrap. This helps protect against fire in case of oil leaks on the wrap. There's been cases of fires where the wrap will catch on fire if oil comes in contact with it. I even confirmed the wrap catches on fire by testing of a small patch of the wrap and applied a couple drops of synthetic oil and a lighter to it.

Did you seal the wrap with the spray then try to light it?

The reason I ask is b/c I planned on putting some HD stainless foil over my header to prevent such an incident, but it was too difficult to work with without tearing up the wrap and sealant. Right now it is wrapped and sealed, but I am extremely careful in changing the oil and watching for leaks. If you got it to burn with the sealant, I may start looking back into more protection.

The test piece I didn't seal. I was just curious how easy it would be to catch on fire in case I missed a spot with the Thermo Tec seal. My headers I did seal and did the foil just in case. The foil also adds some more insulating properties. It was $3 for a box of foil and $2 for some wire which covered the entire header so it was cheap insurance. I didn't have any problems with the foil damaging the wrap. You can also purchase the wrap with the foil from Thermo Tec and other wrap companies.
