I am considering getting an Invidia V4,now my question is this. Are the V4 and the Q300 one in the same? they look alike. but some people on here have been saying the V4 is 70mm,but I keep seeing web sites stating it is 60mm,so whats the deal? maybe a V4 is 70mm and the Q300 is 60mm or vice virsa,i dunno HELP!!

 

The V4 is 70mm. Never heard of the Q300.

 

What the heck is Q300??

 

thats the name for it v4/q300 same thing =D

 

v4 all the way baby

 

so is the v4/q300 70mm or 60mm

 

The invidia v4 exhaust is also known as Q300. This exhaust is a 70mm exhaust, just installed it last weekend and was told it was a 60mm exhaust so therefore i ordered a 60mm test pipe. After comparing the two the 60mm test pipe was deinfately smaller then the exhaust. Measured it and sure enough, 70mm for the exhaust.

 

thanks man that does help,because I keep seeing sites stating both it being a 60mm and 70mm,so your saying IT is indeed a 70mm?

 

if thats is true,any recomendations on where to buy,Im looking for a site with a good rep

 

Yes, the Q300 is the V4. Just look at the part number HS00HSGT3.
