I am thinking about buying an armor tech exaust pipe for my trx 300fw 4x4 1993. Is this a good pipe?

 

Has anyone heard of this pipe? Is it atleast better than stock?

 

I have sold this brand exhaust for about 3 years now.

It's as quiet as stock, but the paint finish on it is absolutely terrible and does not last.
You may want to consider havingit powder coated or have it repainted by someone who knows what they are doing.

As for sound, it is as quiet as the stock pipe and is much quieter than the Cobra Utility series exhaust.
It's the best exhaust for the buck for your model in my opinion.

 

Would you know if it improves performance at all?

 

If it does boost performance, it is by accident........and an insignificant gain.
It is designed as an economical replacement for the facotry exhaust.
