Im looking at the obx 2 an warpspeed y-pipe and n1 ebay exhuast.

now will it remove all my cats, its a 95 so i have no emission to pass.


now what power gains do you get from that.

 

Do NOT get a ypipe with an ebay exhaust itll sound like sh*t.

Ive got an ebay catback installed right now and love the sound. You add a Y Pipe and youll have too much flow and not enough noise cancellation.

Strictly speaking of the catback, it wont remove any cats or 02 sensors. You will need to buy an extra pipe though. An Intermediate Pipe for a 2000-2003 maxima, that will give the catback the correct length.

 

This topic hasn't been beaten to death..

Maybe 25whp tops.

 

I have the custom maxima header to tip and its very noisy but not as much as the ford trucks that run around here so ..... but i always wonder how much hp did i really gain. Before the exhaust it died after 5600 rpm, now i have power all the way to the limiter. Would that be 25hp ?

 

With bigger diameter exhaust piping the powerband is shifted up towards the top end. 20-25whp sounds about right.
