Which front pipe do I need? VVT or Not?

[psquare75]

Hey guys, ordering a downpipe for my '15. Sonic. How do I know if I have VVT or not? Two different part #s.

95129305 Front Pipe

SONIC; W/ O TURBO; W/ VVT

95129307 Front Pipe

SONIC; W/ O TURBO; W/ O VVT

My flex pipe is ripped apart.

It seems like the xx307 is available EVERYWHERE but the xx305 is hard to find.. leads me to believe, they all take the xx307?

Correction xx305 is with with pzev (partial zero emissions vehicle) BOTH ENGINES HAVE VVT... Look under the hood on emissions sticker and see if it says ULEV (Ultra Low Emission Vehicles) or PZEV (partial zero emissions vehicle)

What is a TLEV, LEV, ULEV, SULEV, PZEV, AT PZEV and ZEV?
