Tubi on F355

The one on the right looks like it was patterened after the factory "challenge" muffler.

Put it on, your going to love it.

 

Yes, there are two Tubi made for the car. My friend and I had two different Tubi on the 355, too. I had the older one...but don't remember which one.

 

You can do it yourself. Get a parts manual to get an idea of what is involved and exploded diagrams of the car.

I am sure you can do it yourself and I beleive someone posted a how-to for the 348 and it is basically the same for the 355.

 

Yup, the one on the right is a challenge muffler by tubi. I have tried both and personally prefer the challenge muffler over the standard.

Put in on and let us know how you feel about it.

 

It's a fairly easy install. As long as you have the right tools for the job and some idea of how to work on your car it'll be a do it at home job. If you don't feel comfortable doing it though most dealers won't charge much to do it.

 

Glad to hear you got it on! How do you like it so far?

 

Congrats on the successful instal! You will love the sound, the power increase if any is just an added bonus.

 

just a suggestion, but it sounds like the valve might not have been working before as it should have. If your car is a 1995, then probably the vacuum cannister in the rear right side is leaking. If the bypass valve was working properly you would notice the difference in exhaust tone when it opens up. Just a thought...

 

Also, you might experience "Slow Down Light" flashing if you have OBD2, 96+. I have read 95' seems to escape the light issue. However, I had to unwire it due to the light situation.

 

How does the car sound after you install the exhaust?
Do you have cats in place or testpipes?

As my 355 ECU has been remapped, the sound of the car is silghtly different from the standard 355.

post a soundclip for us to hear!

 

Hi, i'm new and was just wondering, you say there's a power increase thanks to the mod, could someone tell me how much this is? does it vary between the different aftermarket companies?

 

Are you refering to exhaust or ecu remapping?

 

preferably both please

 

The ECU remapping on the 355 adds 20hp to the car which makes 400hp +/-
depending on the octane of the fuel you use.

The car is much smoother and has more punch over the rev range. It allows you to pull in each gear longer.

I suppose there is a diff in the performance of the car depending on the company you use, but i'm not sure how different.

As for exhaust, there is no info on the increase of hp.

 

Who remapped your computors? What changes were made? How much$$?
Thanks

 

I'm assuming Powerchip most other ECU tuners won't touch a 355 computer, but I would also like to know from the owner direct.

 

The company is DMS Automotive.

As for what was changed in detail, i'm not sure. But it certainly made my car feel more powerful, stronger and smoother throughout the rev range.
