Goth Exhaust installed

Looks great. What are you going to do about the original exhaust outlets on the bumper cover?

 

Goth makes VERY high quality stuff!! I can only imagine how nice that exhaust looks in person...

 

Another fine example of the artwork performed deep in the bowels of Gothdom!

 

Wow! That is AWESOME!

Thanks for sharing pics Bob!

Way to go Oz!! You're a legend mate!!

 

Awesome! Gotta get a sound clip for us when you can.

Cheer's

 

Oz, any feel to how the bumper will hold up to the hear from the exhaust?

 

Not too good, but here it is!!

Great job Goth! It looks fantastic!

 

Did Oz do that exhaust exit custom for you? That is the way I like the exhausts. Qz strikes me as a stock appearance kind of guy. How many other 355's are running this through the bumper mod? I think you are on target for an improved rear diffuser this way.

 

that's the ticket! Pull the diffuser outlets up into the rear bumper a bit. Will it add downforce? Who knows. Will it look "complete" and purposeful? Oh yes. I think you need something to interrupt the lines of the lower bumper, and this is the perfect way.

BTW, this thread is MEANINGLESS without good video

 

Fascinating !

Not entirely sure about it in terms of positioning though - just because I'm used to seeing the pipes at the bottom of the bumper/fender.

1 question though - as with most exhausts, they get hot. Is this going to be an issue with scorching the rear?

About the unique goth exhaust note... That's what we have been telling you for over a year!!! You described it exactly. Since mine sounds the same way (as did goth's own system), I can picture the way yours sounds too. BTW, goth's exhaust runs cooler than stock, so you will notice less heat. Hopefully at idle you won't fry the bumper especially after a few hot laps on the track.

How would you 348 owners like this bypass for your exhaust, hmm? Believe me I have been thinking about it since I saw this design. Put a splitter precat with the bypass to open at around 3500 rpm, route to inner tail pipes since the outer ones do most of the work - yeow! Not sure if I want the extra weight tho. Yeah, right.

FBB, the bumper outlets were customized for the owner who wanted something different. Goth was thinking of using the stock cutouts to extend the undertray diffuser. Have to wait on his design to see how that will come off.

The gothspeed lab never ceases to amaze me.

 

Wow Kudos to the OP for going "different" then

No pun intended, but it sounds like an interesting alternative to the other exhausts.

As can be seen by my profile, I know FOOK all about Ferraris, but I'm here to try and learn

Then the car will follow

Cheers

Looks very neat and tidy and the ease of fitment means the workmanship must be very good.

I am not a fan of the exit position though, I am curious if it is in this position due to performance gains or as simply a style?

 

Diffusers look very cool in general and work when designed properly. In my own case of a home made diffuser I can't say for sure if it worked or not. When my 348 was a racecar the giant rear wing in clean air could be felt instantly as could the large 4" splitter put on the car a year later. The addition of the rear diffuser I could not feel at all. But with a 355 having the aero undertray ferrari claim 150lbs of downforce the first production car to have real performance oriented aero undertray. There are significant improvements in the rear of the 360 design that was noticed instantly when the 360C started racing. One would think a ripoff of the 360 design could be a good place to start. I also think something should be done to reengineer the challenge grill concept. I think it adds aero drag. Years ago in the 70's p-bug racers used to put holes in the lexan rear windows to vent the cabin while racing. What was discovered later was those holes encouraged flow in the sidewindows and out those holes = aero drag. I think the challenge grill is doing the same thing. Since the gothmuff is running cooler less heat needs to be extracted from the back. Someone needs to work on getting the heat out without piping air into the engine bay and trying to extract it out the challenge grill.

 

How so? How did you determine the flow of hot air in the compartment?

 

LOOKS SWEET!!! Waiting for the sound clips.

 

Great to see !! You did a great job installing the tips into the bumpers !!!

We bounced ideas as to what exactly Bob wanted. He absolutely wanted it on the quieter side, maximum flow, full F1 sound and a unique exhaust exit location. After bouncing ideas for a while this is the configuration that was settled on .....

The tips in the bumper are indeed separate from the muffler .......... just like the Scuderia !!!

That exit tip configuration has an added benefit that has been used on aircraft for a long time. I have attached a simple pic of the bernoulli effect at play with this design . Also a pic of an actual scuderia tip.

........ and our final photoshop pic which shows the extended diffusser provision in the lower bumper ..........

Sweeet! How about the GothGrill?

 

I wondered the same thing.

Goths grille imo is more functional and looks really good at the same time...more so than the OE CH one.
