I would recommend to buy the downpipe from Redstar, you can choose exactly the setups you want at a really reasonable price (catless or HJS 200cel or GESI 300 or 400 cel, and heat shield or not).

The HJS is more expensive than GESI, that is correct.
But I disagree with GESI not being as good as HJS, as far as I know, and might be wrong; no data was ever posted comparing the 2.
In the US, GESI cats are EPA approved; HJS is not. So one might argue that GESI is better here than HJS.
They both get the job done with no CEL. I don't think you can go wrong with either one.
