Yeh i think you would need the headers on. I think they might need to adjust the length of the flex pipe in order for the length to be consistent to stock i would assume.
But anyhow, I will let you guys know if i can find out when i get mine installed.
Looks like it'll have to wait til next sat then. :(
Just measured the topspeed out pipe and it is indeed 2 inch.Quote:

For the sound. And there is still resistance in the resonator and mufflers, plus that splitter section which looks like it is squished a bit before the split.Quote:

Are the J's racing headers straight bolt on?
and how are they compared to Toda?
think both toda/j's racing and 5zigen headers needs to have cat made to suit.
thanks man...would j's racing make similar power to toda?Quote:

don't know too much but i reckon on par headers would be maximworks/toda/j's racing/5zigen.<--- as these brands of headers were designed for track
J's racing headers have no flange to bolt up to the cat. So you will have to weld on a flange. Also, it does not have a pre-cat O2 sensor port, so you will have to have one done up either in the header (which I don't think is a good idea) or on the aftermarket cat side.Quote:

I got my header back with a new double braided flex pipe. :p
