Default Can I replace heat shield with heat wrap? Where to start wrapping?

I have seen quite a number of posts including unabomber's post on wrapping the headers and uppipe. But they have seemed to cause me to ask more questions.

I bought a TurboXS GT turboback used for my '13 WRX hatch. I installed it and noticed some rubbing on the heat shield behind the transmission and the midpipe. A friend and I spent some time tweaking the bolts but I still get a buzz. I called TurboXS and asked them about putting on KartBoy's XL 12mm hangers and they said that I shouldn't buy them and told me to tweak the exhaust.

So I came to the conclusion that I should wrap the exhaust and remove the heat shield. After reading unabomber's post I feel that I might need to wrap the headers all the way back to my trouble spot. But that is like 150 feet of wrap.

So has anyone used the kartboy hanger's with this exhaust. Any thoughts on the wrap, does it need to start at the headers and go back?

its gonna be a challenge to wrap the pipes on the car. i personally have a ptp turbo blanket and my tomei headers and upipe are wrapped with dei lavawrap. stuff works great and is easy to work with. see if you can bend or trim the heatshield where its rubbing.

I trimmed my heat shield around my dp and only have 1 bolt losing it on. It works great and has no rattles. Just check it every few months or so. I have not once had to tighten the bolt. It keeps heat from intercooler better than after markets shields too

I had rattle in the exact same spot as you with the same TXS system. I managed to successfully bend the heat shield out of the way. Many people have removed it all together. You will get heat soak into the cabin on very hot days in summer, but you will likely otherwise be okay. Doesn't hurt to pull the pipes all together and wrap them, but they have to be off. I personally wouldn't use longer hangers solely because it would look terrible and cause clearance issues, but that's just me.

OP mentioned hangers. Why do you think he means the turbo heat shied ? There is a heat shield all the way back...

Sorry I may have needed to be more clear. It is rubbing about half way back. The rattle is the heat shield that covers the drive shaft about where the rear passenger feet are.

The other question though is it worth wrapping the turbo back only or should I do headers back?

Will wrapping the turbo back cause heat issues in other areas of the exhaust system? Like melting my rear bumper?

Is there a legitimate reason that your warranty would be void for wrapping your headers?

We always recommend against wrapping exhaust products. The wrap retains moisture against the surface of the pipes which can lead to accelerated corrosion and may cause failures.

Ceramic coating is a far safer alternative.

when you say "may cause failures", is this if the wrap gets wet all the time? is it 20,000 miles from now or 100,000 miles from now? and are the failures corrosion holes in the stainless?

Seen this first hand with v8 headers wrapped with DEI exhaust wrap. The headers were falling apart, and the DEI was deteriorating so bad I was covered in fiberglass.

Fiberglass wraps are going out of style. Use the lava wrap and paint it with high heat paint. Wrap the wrap with aluminum tape. This will add further protection to the wrap.
