Invidia TP Vs FI TP
 

I have a FI non res exhaust, and looking to get non res test pipes.

I have the choice to buy invidia non res test pipes, and possibly some others like FI.

Is there any difference between name brands?

If you have an FI exhaust, why would you not purchase an FI TP? We all know the high quality of FI.

Invidia diameter is 60mm, which is slightly smaller than the FI test pipes. I'd match them with your y-pipe diameter for best results.

Chances are I find FI TP for sale is slim to none.

What brands will fit?

F.I. well and sands their flanges from the inside, providing less turbulance as air moves through the connection points. Most others weld on the outside and you have a steel pipe that air can hit and cause more turbulant flow. It's better designed period.

Call and order from FI directly.
