Hi guys just want some advsie really, is it worth getting a pre cat down pipe fitted on to a standard z20let with standard zorst?? Would you get any power gains or would you only really benefit from it after a re-map.

If you do get power gains on standard, are they noticable and how much would you get??

You wouldn't see many gains from it tbh. But its a stepping stone to a good exhaust system which when linked with a map and a few other miner mods will unlock a few more bhps

I think most people see more gains by replacing the precat compared to the main cat. As said you won't notice a massive difference but if your planning on changing the zorst then you'd be a fool not to.
