im buying a cattman Y pipe for my car but i heard that if i want to get hotshot headers after i install my cattman Y pipe i need to take out the Y pipe and only have the header. does this make sense to anyone does anyone have both togher and does it make a diffrence and whn do u feel it ?

 

the hotshot headers contain its own y pipe and no the cattman will not be compatible.

 

If you want the headers, do not buy the y-pipe. Obviously the headers will provide more power than the y-pipe alone.
