Hey guys,

So I got a good deal on invidia test pipes but found out that they are 50mm which is about 2 inch. I know I should have gotten the 60mm, but you guys think there will be a noticeable difference in the pipping like power loss or something? Thanks

 

60mm would be better I think, maybe sell them. Z1 60mm test pipes are $160.

 

way too small.... On the flip side the back-pressure may create more torque lmao

 

Yea, I heard it creates more torque too. Would 10mm make much of a difference? Just hope it wont block flow compared to the stock cats

 

You won't see more torque with 50mm over 60mm. Z's don't make torque NA either way. NA Z's are all top end, gearing can compensate for low torque.

 

if it were me, i would sell and get the correct ones, basic test pipes arent that expensive
