OEM I.D. 29.12mm


DC I.D. 32.06mm


OEM O.D. 28.15mm


DC O.D. 34.36


Top Yaris Manifold Header bracket - Bottom Prius


Swapped out the A/F sensor during the install since I rolled over 120K


Even with new bracket the DC bolt doesn't line up perfectly - 1st attempt of drilling a new hole failed, easy fix tho... Note the exhaust flange that was made...

At this time, no noticeable loss in torque (luckily for the MG2) - however the gains in the higher RPM range is def better. Doesn't appear to be any dB increase either in the exhaust...intake noise is loud enough. Can't wait to finish the exhaust with some Magnaflow mufflers.

Keep Modding!

 

The DC header didn't line up with the Prius header back system. I had a custom flange made to mate the aftermarket header to the 2" piping leading into the 1st catalytic converter. Also had to get a different exhaust doughnut. Seen in the picture below, I'll try to get better pictures later.


As I mentioned early, this was just the beginning.

Next on the list is to cut off the 2nd catalytic converter and resonator and replacing them with (2) 6"x14" round Magnaflow mufflers using all 2" piping. From there I will entertain the idea of dumping the exhaust after the 2nd muffler and if its a little too loud, I may do the remainder in 2" mandrel bends and add a 7" round Magnaflow in the back.

 

Magnaflow has a muffler called the Magnapack #10444 with 2" in/outlet and 4" round body similar to the cherry bomb glasspacks. I used those on my first car back in '91 - wasn't a fan of the sound. Even considering such muffler I measured the oem resonator and its closer to 6" round body. So I'm pretty sure I'm going with (2) Magnaflow #12614 with 2"in/outlet 14" long and 6" round body.

 

Puddle lights installation.

Thought This would be a good place for the lights.

'Rollin on rubber bands...' - yup! Car corners even flatter than before... Have noticed a 3-4mpg loss - mainly city driven - highway not nearly as impacted...but soooo worth the look considering I'm still whooping most non-prius family cars on the road for mpg still!...

 

Potholes yes, legit speed bumps are not so much an issue....and the ones we do have, I've become more aware of where they are on my normal routes so I can either avoid them all together or know when/how to get around them.

 

Thanks! They are nice n bright and easy to install. Nice to to have when the lady is walking up and the car greets her with some courtesy/security lighting.

 

Thanks! Ya, a few changes... Then...

...and now..

 

Thanks!

Possibly, I was concerned with the light conflicting with the movement of the Mirror motor. Let me see if I have a better picture of the light and motor setup.
