Just wondering if its worth it? I have the berk TP right now. My exhaust is the skunk 2, Which is 70mm splitting into 2 60mm pipes. I was also going to get the rear section redone with 1 70mm pipe. Any gains or just not worth it to upgrade the TP?

 

i think its worth it... but i dont think gain will be minimal

 

It is always best to have your test pipe match your catback size... less turbulence.

 

yeah dont bottle neck your exhaust.

 

It's not a bottle neck if the exhaust manifold outlet is smaller than 63.5mm, which it is.

 

Turbulence? What?

Wouldn't this only be an issue if he went from a large test pipe to a smaller catback?

 

I suppose so, but regardless it's a bottleneck right now, and messes up flow... so I guess you could call it turbulence.

 

matching sizes is best. you will make the most power that way.
