will i lose too much back pressure from this combo? i have the berk HFC right now, someone told me i dont want to lose to much back pressure. just wundrin. and yes i did search did find anything for this combo. ill be keeping the rest fo the exhaust stock. just the y pipe.

yea i saw that, doesnt answer my question of going from berk hfc to a 2.5'' y pipe. was just wondering if anyone did this before with good results...

 

Ditto for stock except for megan axle back. Is exhaust depot blowing smoke with their claims of not reducing 'back pressure' and likely hp gains?

 

Old thread bump for opinions on HFC with exhaust depot y pipe on stock exhaust?
