Exhaust fit question

What if any is the difference between the exhaust from the cat back of a
2007 Tacoma access cab with V-6 and one with the 2.7 I-4?
Would like to get a TRD or some sort but all anyone lists is always for the
V-6. Just because I chose a 4 cyl. for economy reasons doesn't mean I don't like a little extra power and noise too.

 

TRD exhaust is nothing more than a smaller muffler on same pipe:eek. TRD intake is nice, fully inclosed ( keeps the mud out)

 

i like the trd
