Just had the Cattman SS Cali-spec Y-pipe installed at Jeff's (MaximumTuning.net). It looks great and the car feels like I don't have to dip into the throttle as much to attain the same acceleration as I would without the Y-pipe. The ECU will be reset to help it adapt faster to the better breathing.



Check out my page for more install pics.......... next is the Cattman Mid-pipe

 

Did you experience any banging during hard acceleration ? If not, did you lower the center brace underneath the car with washers ? The pipe looks cool though.

 

No banging during hard acceleration...... but I believe that was/is an issue with the '02/'03 guys.....so the center brace still has plenty of room.

 

how much does it cost to reset the ECU? and is it needed after installing the y-pipe?

 

I understand that you can do it yourself... the negative battery terminal has to be disconnected for a period of time, I forget how long, and that resets the ECU.

But it can also be done by some code readers. Jeff at MaximumTuning.net reset my ECU (free of charge) after he installed my UDP.

 

what about advanced timing? what are the gains of this and how do i go about doing it?

 

You must be reading my mind man.....I just started researching the boards regarding timing advance. That, along with the Cattman B-pipe are next on my to do list.

You can view this thread Timing advance and look at the sub-thread in the 2nd post for more info....hope this helps.
