Exhaust for VVT swap in 90-97 Miata?
 

Hi to the VVTswap crew,

Which exhaust systems do you guys use in your VVT swapped 90-97 Miatas,
VVT parts? 93-97 1.8 parts?

Thanks for your help!

NA 1.8 exhaust is the easiest. That is what I did......

second the na 1.8 exhaust, plus na cat or test pipe. your current catback will work.

Exhaust that matches the chassis.

Exhaust routing is completely unchanged for all NA / NB cars, regardless of the presence of VVT or OEM turbo.

I'd follow this advice, I did and had zero issues. Swapped a NB1 1.8 into my '92 and used all 94-97 exhaust components.

As above, I fitted the complete NA exhaust.

Whilst the NA/NB route is broadly similar, none of the hangers line up, so it's a ball ache to fit.

Thanks to all of you... !
