There are a lot of options in the SV3Power lineup, and it can be confusing to sort out what you need.  Any car that will be driven on the street needs four basic components: a header (or manifold), a downpipe, a catalytic converter (or test pipe), and a muffler.  This page will help you select the right combination of parts for your car.

There are two basic exhaust system formats: NA (meaning Naturally Aspirated) and SC (Supercharged).  NA and SC use their own specific flanges at the downpipe outlet, cat, and muffler.  So if you choose an NA-style system, those three components must be NA-style; the same goes for SC.

Begin by selecting your engine. Click the link for your engine type to view the header/manifold options that will work for you.

4A-GE or 7A-GE turbocharged (any): Use SC-style components. Turbo manifold and downpipe are available at www.matrixgarage.com .  For other exhaust components: continue

Downpipes as dictated by your selected engine and header/manifold:

Cast iron manifold on NA-style system: Use an original 16V NA-style MR2 downpipe. continue

Cast iron manifold on SC-style system: Use an original 16V SC-style MR2 downpipe. continue

TRD header on NA-style system: Use SV3Power B-pipe for TRD header, NA-style. continue

TRD header on SC-style system: Use SV3Power B-pipe for TRD header, SC-style. continue

Standard-length 20V header on NA-style system: Use SV3Power 20V-to-MR2 NA adapter downpipe, standard length. continue

Extended-length 20V header, or SV3Power 4AGE MR2 header, on NA-style system: Use SV3Power 20V-to-MR2 NA adapter downpipe, extended length. continue

Standard-length 20V header on SC-style system: Use SV3Power 20V-to-MR2 SC adapter downpipe, standard length.  continue

Extended-length 20V header, or SV3Power 4AGE MR2 header, on SC-style system: Use SV3Power 20V-to-MR2 SC adapter downpipe, extended length. continue

Catalytic converters and test pipes as dictated by your selected downpipe:

Any NA-style exhaust system: Choose any NA-style OEM or SV3Power catalytic converter or test pipe. continue

Any SC-style exhaust system: Choose any SC-style OEM or SV3Power catalytic converter or test pipe. continue

Mufflers as dictated by your selected catalytic converter or test pipe:

Any NA-style exhaust system: Choose any NA-style OEM or SV3Power muffler.

Any SC-style exhaust system: Choose any SC-style OEM or SV3Power muffler.

That should give anyone the basic layout they need. There are other options, such as different oxygen sensor fittings and muffler tips, but they are mostly a matter of personal preference. As always, let us know if you need more assistance!
