First of all, :speakenglish:

Seeing as your new to the site, welcome. I'll help you in getting some replies:

Hi.

I have an MG ZR 1.4 and have had a custom exhaust fitted. I have gotten rid of the massive back box and centre box, so it is now more or less a straight run from the cat to a very small back box.

It sounds awesome but it makes gun shot / popping noise sounds. Is this normal? Will it affect my engine's life?.

I need my head gasket done as it's overheating and evapourating coolant. Is my exhuast not helping the situation?

Any help would be very welcome.

The poping should only be when it's cold. Thats the unused fuel been burnt up. Metro's and 100's used to do it with standard exhaust's. It wont effect the life of the engine at all. I doubt the exhaust will make it any worse or better. But get it done before it's to late.

Im portuguese and I understand every single word he said.
So did I. I knew what he was saying, but there was a degree of txt speak which makes it hard for some members to read, and is against forum rules. As he is a new to the forums, I thought i'd help him out.

He also did not use any punctuation, so I did him a favour by making it easier to read. People often scan the forums quickly, and they are more likely to reply if it is easier to read.

Rich.

I thought back-fires contributed to valve burn out?

Is the timing correct? Maybe the timing needs advancing.
