I have an 03 enthusiast Z. love the car and its my DD (designated and daily) driver. i have a few performance mods and just wondering what else i should do before i get my osiris tune.

MODS:
titek test pipes
motordyne plenum spacer
k&n drop in filter.

I definitely want to keep her NA so no fi here. I'm toying with the idea of a y pipe ( i do not want to get full cat back, want to keep as stock as possible from the rear.) i have the test pipe hiss and from what i researched getting a y pipe will solve it, or i'll just have to learn to live with it.

I need some guidance here so any help would be appreciated. If anyone could tell me where a good place in houston to get my tune dynoed and tuned (for a good price) also if anyone knows how to fix the "hiss"

I would free up the exhaust before a tune, the Nismo exhaust looks stock, slightly louder and will provide you the extra needed flow. If you combine it with the motordyne XYZ pipe you will have a high quality exhaust with nice gains.

 

JTran studio in memorial. So far he has good feedbacks. He is in the FI section.

 

more airflow so +1 on an exhaust. Headers aren't worth it. That's about it for NA.

 

Do not listen to anyone, just do what you want since you will get a hundred and fifty different opinions on the same thing.

 

my philosophy is dont spend money on a tune until your 96% sure your done modding. I waited to have a bolt ons besides headers and couldnt be happier. Also i dont agree with your logic of exhaust. If you want true gains running aftermarket to the stock muffler is pointless. Think of putting out a house fire that starts with a fire hose and near the end the last part is a garden hose.

 

+111 get a full exhaust (2.5" true dual, ect) you want real gains. None of this axle back stuff unless all you care about is sound.

 

Get an exhaust

 

Ok so i got a sweet deal on a nismo exhaust from my test pipes back. sounds fricken amazing and the hiss is gone! i used berk gaskets and everything so far is all good. so sitting on full exhasut except for headers with test pipes, plenum spacer and drop in k&n. can't wait for my tune! too damn excited but gotta save some $$$. school is a bill and a half
