I have a HKS replica on my coupe. does anyone know where the extension goes?? does it go on top of the Y-pipe or the bottom of the Y-pipe?? I currently have them on the top but it doesn't sound right. help please?????

 

Doesn't sound right? i dont understand how moving the exhuast 6 inches back would have any effect on the sound. i have the extensions right after the cats before the H pipe and mine sounds just the same as all the others.

 

I thought the extensions went after the resonators, I could be wrong cause I don't have the exhaust

 

they go after the cats, right before the H-pipe
