Looking for opinions SI/SO or SI/DO

Hey guys,

I am looking for opinions on what looks better on our trucks. I have a 2005 FX4 supercab 6 1/2 box.

I am looking to get the mbrp exhaust system and can't decide from the SI/SO or the SI/DO (the one that dumps out the side at a 45 degree angle).

What do you guys think?


Thanks,
Ryan

I like the look of the MBRP SISO, looks awesome with that big tip...I am also a big fan of the magnaflow 16608(duals out the stock location)...looks pretty cool IMHO, if it was out when I got my exhaust I would have done it

Is there a sound difference between the dual and single on the same kit? I am assuming that there has to be just don't know what direction it goes...

I love my roush offroad SI/DO. It's not really an offroad pipe, just a little louder than the other one. It sounds great! Pretty quiet at cruise IMO. No drone and sounds better than Magna and Flowmaster

Get it here. http://www.woodhousestore.com/

I prefer a si/so on this style of truck, I don't know why, but I just think it looks better. So thats why I am running a si/so on my truck.

Well I just ordered the SI/SO version from autoanything.com. Bought the XP version because it has the lifetime warranty also like the Pro (looks the same unless you are underneath it). Paid 383, free shipping, plus another 8% off going through live.com. So paid 350 to my door for XP. I think that is a great value for a cat back stainless steel exhaust...

Thanks

That's the kit I'm going to order as soon as my Roush kit sells. The best price I have found is $345.07 with free shipping for the XP series.
