I just bought an apexi dunk muffler for 94 supra na. I figured as long as I am having that installed, I am considering running bigger piping. What is the best size pipe to run so I want lose any bottom end power, like I would running TT size pipe? I am thinking that I might be best off running the same size pipe as the Greddy MX for the NA. How many inches is that anyway? Any comments on any question would be appreciated.
Thanks

N/a specific pipes are about 65-70mm. Most put turbo pipes on anyway- they fit, look aggressive, & are sold in enough #'s to be cheaper than n/a setups.

i would say go with 2.75-3 inches. you might lose a little low end but youll gain more up top. what is the stock size on the new na supras?

My stock pipe is about 2.5 inches in diameter.
How does everyone like the performance of their Greddy MX? Does it seem to have the right size pipe for the NA?
Thanks

i believe the piping on the greddy mx is 2.5in. since its made specifically for a mkiv normally aspirated, you'd probably get the most performance out of it.

but if you plan on going turbo in the future, then the greddy mx isn't a good choice.
