If you have this on your truck are you happy with it and is loud. Did it help
with gas mpg and power? also were is a good place to buy.

 

wherer this number come from? is that he SI/SO kit magnaflow makes? if so ive heard good things about, i was gonna get it but i got a bodylift and would work out to good for me so i passed.

 

sarah has a 12158 on hers and it rocks. http://www.performancepeddler.com/de...CT_ID=MAG12158

we welded on reducers so it was 2 1/4 in and out. D likes the 142 series cuz they're polished stainless. either or works well.

 

The Magnaflow #15679 Rick is talking about is a complete cat-back kit,not just a muffler.It is all stainless 2 1/2" tubing with a 3 1/2" stainless tip.Looks to be very high quality.I am considering it for my truck also.It can be had for $399 with free shipping.I don't think cat-back kits do much for our trucks(3.0 or 4.0) performance wise or mileage wise.But they do sound and look much better than stock.

 

Well it is done and I am very happy with the way it sounds not to loud and
not too quite the quality is very nice well worth the money I don't know if
it gave me any power but it looks way better ( thanks mrc )

 

I will agree with Rick.Very good quality for the money.It sounds real good and looks awesome.

 

I can only imagine.My Dynomax cat-back is nice but it is starting to rust out already.No snow here in FL but I do live near the beach so I get the salt air.It is aluminized steel.I guess you get what you pay for.It only cost me $160.Rick got the Magnaflow stainless for about $349 to his door.It is definatley worth the money.I am most likely going to go with the Magnaflow next time.
