Not sure about the size i think it's about 1 7/8" vs. the GA's 1 1/2". The B13 SE-R OEM cat-back will bolt right up trust me. I have the GReddy SP SE-R cat-back on my car and it was a simple bolt-on. The OEM SE-R exhaust is a good upgrade for the B13 1.6, it bolts right up it's quiet and has much more flow than the 1.6 exhaust. This is the best sleeper exhaust for the 1.6...MinorThreat said:does anyone know the diameter of the classic se-r exhaust? and would it fit on a 1.6L
No the b13 exhaust won't work on a b14. You would have to use the oem cat-back from a 98-99 SE SR20 powered sentra. The results would be the same,bigger pipe more flow and quiet at the same time...UnderDog said:Will that fit on a B14? Or would I need an SE-R exhaust from a B14 SR20?
