what is the part/model number for a si/so (exiting behind rear tire in factory location) magnaflow cat-back for my 2007 SCrew 5.5' bed 2wd? Preferably with the 14" muffler

is it the 16612?

 

Yea, how do you tell what to use? I go over to pricepeddler, and I see a bunch of numbers and measurements.

 

i looked at magnaflow.com to get what model number it is, then buy the same model at performancepeddler

 

If you have the Crew Cab with the 5.5' Bed and you want the single cat back system Use part # 16612

 

sweet, it will fit my truck being an 07' right? Is performancepeddler.com about the best deal i am going to find?

 

CC is for crew cab and SB is for short bed.

 

sweet, my g/f just ordered me a maggie 16612 ....should be here this week!

question....i had a maggie si/so for my 04 4.6L STX. sounded nice.....is there any difference in how the exaust will sound from a 4.6L to a 5.4L???

 

Anyone know the difference between how a magnaflow sound on a 4.6L or 5.4L?
