I'm sure if TPR could get their hands on a newer GTS header with air injection, it would be very easy to modify their upcoming 4-2-1 long tube race header to work with it. smile Any volunteers? wink

TPR 4-2-1 Long Tube Race Header

- Made of polished T304 stainless steel
- Mandrel bent piping
- True 4-2-1 design unlike stock, Trial, TRD, and DC
- Anti-inversion primaries to maintain forward exhaust flow
- 2 piece design for easy install: top half has primaries, bottom has secondaries and collector
- Provisions for adding EGT sensors (on primaries and collector)
- Mounts onto stock header mounting bracket
- Flex section on collector to eliminate stress and possible cracking

TPR Midpipe (compatible with TPR race header)

- Made of polished, mandrel bent T304 stainless steel
- OBDII compliant, CARB approved cat (stainless steel)
- High flow resonator (stainless steel)
- Mounts for stock O2 sensors
- Extension wires for O2 sensors
- Completely bolt on: install in your driveway
- Compatible with all aftermarket bolt on exhausts

The TPR race header and midpipe are planned to be sold as a package, since the header is too long for the stock midpipe. It's definitely possible to get the stock midpipe shortened to fit the race header, but the 2.25" stock piping would result in restriction and power loss.

A midpipe to fit stock style headers (Trial, TRD, DC) may also be released, so even if you don't have the TPR race header, you can still gain the power of a 2.5" midpipe. Adding the TPR midpipe to any aftermarket exhaust would also be the equivalent of having a header-back exhaust, but would be much quieter. wink

No, not at all. In fact, it will make adding the header by itself easier than on the stock midpipe. All you'd need to do is cut off the front of the stock/kazuma pipe right before the first O2 sensor and weld on a flange to match the TPR header (not sure if it will be a flat flange or a ball flange yet). Then, just cut out enough of the Kazuma right after the second O2 sensor so you can move the cat far enough back to fit the header. smile A piece of cake for any exhaust shop. smile

Hmmm, can you get me a few pics of the stock header? Just wondering how the injection system is integrated into the header. TPR is based in MA, but its shop is in CA (EasyC is actually there this weekend).

Probably just a CEL, though what that would be I don't know. I'm not sure if it would affect the car's Performance or not, since I'm sure the O2 sensors have been retuned to match the extra fresh air in the new system. You definitely won't pass emissions testing with that CEL, either.

Newer GTS' and Matrix XRS' have a small turbine that accelerates fresh Intake air into the exhaust gas stream before the cat. This helps the cat burn emissions more completely and efficiently.

...may-b i could illustrate...where the stock header bolts onto the engine, there are four small holes on top of the manifold ports...the stock header has a inch in height metal piece that covers those four small holes...and a tube running out of the right side top of the stock header(bends around the top of the engine near the tensioner) connecting to an air pump next to the dip stick...hope that helps a little but ill def. post up pics...coo
