I emailed them about that and they said they could not do that. Maybe after a while, if they change up stuff but as of now, nope.

i've considered this option as well. i like apexi products, but am not a huge fan of the exhaust ends. i thought about getting single outlet (like the is350) system, but thought, nah...haha. i'm afraid that after market parts are going to be very scarce like the cars themselves.

I wonder if anyone would actually catch that on a visual inspection... if they're slightly careless/hot/in a hurry they might not even notice it has been changed.

i love modding cars because it helps in making them quasi unique. for example, changing rims or a kit for aesthetics. but i also like adding things that are functional as well like adding tint, intake and exhaust. with that being said, will changing the midpipe alone do anything other than change the tone of the exhaust? seeing the dynos and reading about the "crushed" section of the axle back, it doesn't seem like changing the midpipe would add any power or torque. changing out for cat back shows more hp and minimal tq (maybe loss due to lack of back pressure). just curious. feedback would be appreciated.

the exhaust air will pass through the midpipe smoothly but will go back to the crushed sections of the oem axle back. i'm not sure if the diameter of the oem axle back is smaller, but if they are causing some restriction on the way out. in theory, this may result more back pressure and maybe more tq?

It is a widely spread myth that some back pressure on the exhaust is good, however this is the wrong conclusion of experimentation. Back pressure on an exhaust does not increase performance for naturally aspirated (NA) or turbo applications. There are situations where smaller diameter pipes can outperform larger diameter pipes, but this is not because of back pressure. Instead this is due to scavenging, which, when properly tuned, can actually reduce the back pressure as seen by the engine further

Don’t confuse back pressure with scavenging.

i can’t tell you how much benefit is received from a mid pipe, but it will flow better because there’s less resistance. Tuning can always help.
