Stock manifold changing collector
 

im planning to change the Overpipe to (Motiv2.5/63mm), im using aftermarket (catback2.36/60mm) with (catless downpipe2.36/60mm)
since ther is no an aftermarket overpipe size of 2.36/60mm. im just warry of losing Power in low range or high because I heard large to small piping not worth it. and may result in bad power/TQ.. :burnrubber:

The OD is 2.5", the ID is 2.36". You will be fine.

Dude you are talking about less than a 1/4 of an inch (because Merica) difference here. That is very negligable and you don't need to worry about it. There are tons more places to find power and worry about than this.

get the motive over pipe and the motive front pipe,.. they are both 2.5" then sell your existing 60mm front pipe if your worried about it.

what about the rest catback 2.36inches:iono: throw it no nearly garbage:hitcomputer:
