6G Celicas Forums

You could save a lot of weight by eliminating power steering altogether!

I tried to find a mirror from a vert as well but everything I found was in rough shape.

For many years the gray mirror has bothered me on my all-black Celica. Recently the day-night switch got a little sticky so I had a good excuse to do something about it. I cut the mirror open and cleaned and lubricated the mechanism. Then I smoothed it and painted it satin black. Today I reinstalled it.

NICE!!!

Finished triangulating my GT-Four rear strut brace.

Started work on triangulating my rear strut brace, something I have wanted to do for a long time.

Gorgeous car.

Sounds like great news.

Thanks for your post, Bitter. Very helpful. That's a MagnaFlow 94405. About 7.5 lbs. I'm quite happy with it. They are available in other sizes. With the straight pipe in place of the rear muffler it's amazing how quiet it is. Too noisy for my taste but much quieter than a fully open exhaust would be.

It's amazing how cool the engine compartment runs now, it almost feels like you could touch the header while the engine is running. I am using 93 octane and I think it's safe but I will look into the knock sensors.

I am still running the stock intake including the snorkel. I should try removing it.

Thanks!!

The Celica turned twenty-five years old in 2018. That made it exempt from future emissions tests after the 2018 test, which it passed easily, as usual.
This gave me the opportunity to build a custom exhaust system. I did use a catalytic converter, and it would still easily pass emissions.
But with improved flow, lighter weight, and better sound.


Stainless header and downpipe

I started with a 4-into-2-into-1 "tri-Y" non-sequential stainless steel header made for a Corolla.


Fitting header

These two pieces saved fifteen pounds and they look a little bit better too.

New and old parts

I got the header and downpipe ceramic coated. This keeps the engine compartment much cooler and it keeps the exhaust hotter, reducing back pressure and improving catalyst performance.

Installed ceramic coated header

I decided to go with 2-1/4" tubing and a 2-1/4" catalytic converter, resonator, and muffler.


Exhaust system components

I selected a Magnaflow stainless catalytic converter with a built-in resonated core for further weight savings. I also selected a Magnaflow oval muffler.

I installed the downstream oxygen sensor after the catalytic converter where it belongs.

Hanger at front of muffler


This is the first rear muffler hanger

For some reason I had trouble making a rear muffler bracket that I liked and over time I ended up making four before finally settling on the bottom one.


Muffler rear hangers

I also made a long straight pipe that can be used to replace the muffler which was easy since the muffler has central inlet and outlet.


Tail pipes

Along with the exhaust system I advanced the ignition timing from the stock 10 degrees up to 15 degrees BTDC.

The end result, lighter weight, better sound, and a little more power.

This might help.

I need this bracket from the back of a Celica GT.

The green Celica looks excellent!

WRB BRZ ftw!

RCR GT40 replica delivered today!

Very nice work! Love the attention to detail. Can't wait to see more.

The lurkers are happy too.

Do it right and get the front and rear GT brakes plus the proportioning valve. GT front brakes are much more effective than the ST fronts and it's the fronts that do most of the work.

Agree 100%

Which is more beautiful, the Supra or the scenery?

You've got a great starting point there for a car you can enjoy and depend upon.

Of the few, basic mods I have done to mine, the GT brake swap is my favorite so far.

Way to go!

Something just doesn't look right about that photo. I wonder if your clutch failed.
