I know this is a repeated question, so I'll get to the point. Exhaust wise I am going with the Spintechs. As far as the x pipe I think I read that the magnaflow had a better fit. Is this true? Also since I am too lazy to go look at my exhaust, does it have a true dual or is it better for me to make it a true dual. What model spintechs are you guys who use them using? I think its the prostreets if I am not mistaken. I called a shop yesterday that I have my nova at and they told me about a trick setup they did on a R/T. Two ex pipes for the O2 sensors with highflow Cats and two spintech mufflers. Is all this necessary for proper reading of O2's on our trucks? I have seen a pic of two spintechs side by side with an x pipe before it and turn downs. That looked good whoever had that. What prices are you guys paying for the x pipe? Ok sorry for the book.

 

Do the SpinTechs flow better than the Dynomax Ultraflow? What x-pipe are you planning on using?

Here is a thread w/ pics of an exhaust using SpinTechs and a x-pipe https://ls1tech.com/threads/showflat...31&fpart=1

 

Yeah, thats the same thing I want to do but exit at an angle out the pass side in front of the tire. I don't need the resonation, since I have a system in my truck. As of now I plan on using the spintech x pipe and spintech prostreet mufflers. Any ideas on exact size? I saw 2.75, is this right?

 

if you don't want resonation then don't have it exit out the side of the truck...i've had mine done that way two different times with two totally different setups and they both had a good bit of cab resonance and sound

 

I am gathering that I should exit out the back? How much resonance if I just go out the side before the rear tire? I want something that looks good too. Over the axle is too common I think. May have to though. Is the exact size 2.75? Thanks for all your advise
