Titanium 308 Exhaust

BTW a Superformance exhaust IS a Nouvolari one for less money. Excellent quality. I have one and it is superb (replaced my mild steel Ansa unit)

Titanium is tricky to weld and can work harden if it is not done properly. This can lead to the system cracking easily. Also the commercially available Titanium parts are not true high end Ti so the weight gains are limited.

 

I've never understood the point of the final 'split' into 2 pipes at each tip on a Tubi exhaust. Presumably, it is purely cosmetic - which puts me right off.
I'd prefer 2 single pipes - if they did look a bit feeble, they could be made a slightly larger diameter.

If you go custom, I’m very pleased with 12”Flowmaster Super HP 2’s. I like the black, but they are available in 304 SS. They remove the annoying drone of some exhausts, have a nice sound at idle, and great sound on throttle.

I have never looked inside an Ansa or even a stock exhaust, are they a true dual like the custom unit shown , or are they "merged" internally, with just dual outlets?

I ask the question, because dual exh can be somewhat peaky compared to a merged dual system. Merged being an H pipe, or X pipe that combines a typical under car, front engined dual exhaust, or two exhausts that flow thru one muffler and combines each side. I picked up an extra 225 ft-lbs of torque on my 427 Corvette, at 1500 RPM by adding an H pipe to connect the two sides right behind the header collect , didn't make any diff above ~2300 RPM, though. But, at 1500 RPM, the rear wheel Tq was 400 ft-lb with the H pipe, only 175 ft-lb, without the H-pipe.

If you ever wondered what is inside of an Ansa I cut my old one open and documented it here:

Based on the weight of the stock muffler, I thought they were made out of lead. Based on the price of a new muffler, I thought they were made of gold!
Thanks for sharing Rob.

 

Well, that was interesting, thanks.

My eyeball estimate based on general muffler experience is the Ansa is a so-so muffler as far as robbing HP. I have seen worse, i have seen better designs. I do have a c. 1987 Ansa muffler on my car now. Have to think about putting something better on there.

My understanding is that on a cross plane crank, the H or X balances both sides to help scavenge the exhaust. With a flat plane crank, you essentially have 2 four cylinder engines that are already balanced, so the benefit of an H or X is not the same. I’m sure others can elaborate and/or correct.

This is correct.

 

Tubi is the absolute best exhaust system for a 3x8, its that simple. The build quality, the period correct sound, and mated with a test pipe, your car will wake up from its cat converter sleep.

Thank you

 

Maybe you have a Euro car, Im not sure, but the test pipe replaces the cat converter, the motor compartment will be at least 15 degrees cooler, and the car will run cooler when in traffic .

Thank you

 

Then you dont need one, Its strictly to replace the cat converter
