What kind of power difference?
I'm wondering if anyone can give me an idea of the power increase I'll see with my mods.
1)Mac 94-95 single cat style Jet-Hot coated headers and y-pipe
2)Mac off-road pipe Jet-Hot coated
3)Borla 94-95 single cat style cat-back
4)02 sims
5)Taylor OVC wires
6)NGK TR55 platinum plugs
7)TB bypass
8)new 02 sensors
The car is a 97 WS6 with factory ram air and a k&n filter. It has 40,000miles, is a 6speed and is run with Mobil 1 5W30. Also, what do you think the car would dyno?
Thanks

power difference
I didn't get mine on a dyno but from my own estimate and from doing A LOT of reading on this board, but adding mac headers and a K&N FIPK should bring about 25-30 RWHP.
In my opinion, next to a cam, they are about the biggest increase in power you will see. Nice SOTP increase and a very worthwhile addition.
In hindsight, I would not change the stock cat-back. It's just not worth it. The muffler, headers, and Y-pipe - yes, but not the cat-back, I would put that money elsewhere.
Hope this helps

Why exactly would you put headers and y-pipe but no cat-back? The cat-back is the cheapest and easiest to do, and you can definitely pick up gains there....if you do headers/y-pipe, then that becomes your bottleneck. Unless of course you mean just get a cutout....
