I'm about to purchase one of the M2 Y pipes, the HR design is 65 dollars more the the DE/nismo "replica" design. They both have 2.5" Inlets, and 3" Outlets.

Is the HR design really any better performance/sound wise? Or should I stick with the de nismo design. Any help would be appreciated as im trying to get this ordered tonight. Thanks guys.

 

the HR design has better low-end response, the "classic" y design yields better top end(from what i've seen, HR cars putting DE-style y's gain some on-top). it's really personal taste, people like the HR style because it gives you a boost in your normal/usable everyday power-band.

 

I just ordered the hr style....

I'm hoping it gets some of my rasp :/ I have some mis matching pipe diameters.

 

Yea some of your rasp will go away^ mine did but not all
