so i finally have money to start hooking it up so im ordering the aw headers and injen cai this week first question is will i run into any problems with these like in general

2nd wat i feel a bigger gain if i was running with those 2 parts and no axle back

3rd question if i add a light weight pully and a custom catback exhaust will i be around 180 to the wheels?

 

1st question sometime the o2 sensor in the factory header has been cross threaded from the factory. the bolt holes on the header might be cross threaded. The alignment on the bottom flange supports might be off.

2nd you will want to run a axle back.

3rd. you might see that at the crank with these mods not at the wheels. expect 155-162 to the wheels.

 

thank you

 

I also had to stack some silicone spacers on the mounting flange for the oil dipstick, along with a longer screw so it would clear the first runner of the header. On the injen CAI, getting the cold pipe into the fender opening can be a biatch.
