Title: Toyosporr
Post by: Newbie57 on November 29, 2025, 05:01
What's everyone experience with this manifold.
Have had one fitted to mine now. Is there any major issue with it not having the support bracket from the engine to manifold at the bottom.

Perfectly good manifold for the money. No issue not having the support bracket.

As Iain says, no issue - it's so much lighter than the pre-cat manifold.

I do recommend wrapping them, though, both to keep the heat down in the engine compartment (the original manifold has a big heat shield) and to improve flow of gasses. I use heavy quality 'Gold Titanium'.

I have run a Toyosports for over a decade.  I also run a Cats2U cat, which I also wrapped as a hot cat works best, and, again, the OEM cat has a heat shield.

Many of the early other brand "clone" headers had a tendency to crack from vibration when the lower mounts were not used. We went with one of the cheap headers over 12 years ago that had the heat shield mounts as the OEM shields were required for emission system compliance here in the US. We added the FL cast lower mounts and the manifold is still fine. 

No experience with the Toyosport, but it appears to be a heavier construction.  You will also find many different opinions on wrapping headers or not wrapping.
