I already have custom efr6258 manifold and downpipe installed on my car. However the fabricator designed it too close the firewall and now the downpipe is almost touching the master cylinder and
the heater hose (See attached photo). I am unable to come up with a satisfactory solution to this and thinking of just replacing the manifold and downpipe with pre-built setup. Mine is 97 Miata with 99 engine and Non V-band EFR6258 with internal wastegate.
Any recommendations on who I should get the manifold and downpipe from?

Cheers

 

Tell the fabricator to try again.

 

My guess is that he built it for a 2560, thought it would work for EFR because bolts. Nope, the EFR is just a monster in size. TSE and be done.

 

Unfortunately this was fabricated two years ago and I just got to installing it couple of months ago. The fabricator has moved on/away. Gone ADIOS.
I see you have ARTech. How do you like his manifold and downpipe?

 

Ryansmoneypit is right wrt the length of the EFR.

I absolutely love my Artech manifold. It's made great torque. I have everything that Abe was willing to make for me and the quality is pretty amazing. TSE spent a lot of time developing their kit and it's a bangin setup. You'd have to contact Abe directly about whether or not he's taking on manifold projects or only doing exhausts now.

Can't go wrong with either option.

 

Cut or bend the shelf parts and make it work. Add heat shielding.

 

I would say buy my parts, but honestly, my stuff is going to foul in the same places. Moving the prop valve and heater hoses is de rigueur for turbo installations here.
