First off i searched, and failed. I know the injen intake yeiled a 14.3whp gain so that will be purchased. Now i need to move on to exhaust. Anyone bought exhaust yet. I know the obx headers are 700$ not carb exempt and will most likely need an o2 simulator. I already have a high flow cat for the secondary now im looking for exhaust. Something that can be heard from the outside and be noticed but not make me tone deaf inside the car. Any suggestions. I was thinking apexi ws but 660$ for something that might be toooo quiet. Any help would be great pics are always welcomed.

...really?

 

How much torque do you lose off of that intake if it gives you 14 whp...?

 

Well you should probably start with intake and then catback from Greddy or Tanabe cause they are not too loud. As for headers i would say you cannot really get them because the exhaust manifolds are cast into each head so all you are getting is a bigger b pipe.

 

That car has 3 cats on it.

2 are directly after the connection between the manifold and the head, one more is at the end of the downpipes.

Rip the third cat out. You will NOT get a CEL as there is no o2 sensor after the third cat.

I suggust 2.5" - 3.0" piping after that.

good car!
