OH YEAH!

Great to hear.The extractors heat up the oil which heats up engine and then the coolant.After 10 minutes of flogging it on the track my car was overheating and I had to let it cool down,so on the 28th of june,the next trackday it will be good to note the change! I know there will be one,I'm very happy with all these benefits of having wrapped headers,no wonder I wanted to do this for ages!

There's a definate performance increase too,definately.

Thanks mate.
