Does anyone have experience with header or exhaust wraps? Are they worth the money? Performance gains or losses, etc? Thank you in advance.
You can see a slight power increase due to lower underhood temperatures and
also higher exhaust velocity with a wrap. Just don't expect to see huge
power gains. As for if they're worth the money you'll have to try it and
find out what you think.
Although it costs substantially more, getting your headers ceramic coated does the same thing only better. It also looks really good and keeps the header from rusting.
