Hey guys,
Thinking about future mods im definitely going to look into a hot side boost tube either alta or NM. I haven't yet decided if im going to do a cold side as well, but if i did both id want them to match-both NM. Im wondering what the cold side tube does if anything at all, if it isnt anything significant then I'm thinking I'll just do the one alta hot side.

 

I have done both pipes. Cold side installed first. I didnt notice any difference from the cold side. It was designed to replace the factory one that had a noisemaker. The newer cars dont have that anymore. Unless you really want to do it I would spend my money on something else.

 

thanks, also how do you like the nm torque arm

 

The torque arm insert is a must have.
