The mugen header is very good and a fair bit better than the likes of megan, dc etc!! The toda would be slightly better but for the 2bhp extra that you might gain from a toda its def not worth spending £1100
If you have clearance issues underneath with the mugen if its a 4-1 then try the new Tegiwa Toda rep manifold, looks great
Or £500 second hand.
Tegiwa one seems good deal but yet to see a tegiwa-toda comparison?
I have driven loads of miles with MUGEN 4-1 and never had it ground out. You just have to remember it's on there and be cautious.
Dunx
i had mugen on mine and put standard back on the only diferance was the sound imo couldnt feel any with the butt dyno lol but maybe im used to propper fast cars
Mugen 4-2-1 is what I had, they are pretty rare so i am told. But I recently sold it because I flattened the tube (car is low) I replaced it with the Tegiwa Toda Rep. Its not been 1 week and I already put a flat spot on the tubes. So Clearance wise regarding both headers are pretty similar.
I wish I kept my Mugen tbf, I thought this Tegiwa one would be better clearance. Clearly not.
I dont think the clearance issue is with the manifold. Its more with your suspenssion. Iv seen pics of the tegiwa toda rep and it sits alost level with the sump, if your bashing it that hard god help your sump.
did you remap when you changed to mugen?
Mugen GOOD! mugen good...mugen good mugen good
