Im hard up for money right now, someone wants to buy my J's exhaust.
Was thinking about chopping my OEM one up before the Y split & running that so I can sell the J's.

Like this guy did..Cheap/light exhaust


Since they are both 63mm exhaust, it should affect the tune much, right?

This would just be temporary until I can put on my 3" exhaust.. dont care what it will sound like

 

dude, you should have went with a cutout.

 

the cat is going to kill you the most. Unless you have a test pipe. It shouldnt affect the tune much just take a peak at your A/F's

 

It will definitely affect your tune, by how much I'm not sure.

 

guys thats not my car in the pic.. i have a 63mm test pipe

What do you mean by "cutout"?

 

Cut out is a mechanical (sometimes electrical) gate on your exhaust that you can open or close with a switch, effectively bypassing the cat and muffler. There may even be a spring loaded type that opens with the right amount of pressure, but that would just be too cool.

 

I was thinking of picking up an ap2 exhaust and weld in a cut-out. So at first its quiet then when it reaches 7psi or so it will open out and scream.

 

thanks for the explanation.. that is a pretty neat idea
