I think I'll start a new thread to show the "mystery part" that's coming next.

Exhaust Cross Pipe
It's finally done and up for sale. We went all out on this, it's make from 304 stainless including the welds and mounting flanges. All the included nuts and bolts are flanged and serrated nuts which makes installation relatively easy. The 304 stainelss provides a good temperature barrier but to provide further temperature protection to the slave cylinder, oil, and transmission we include Mishimoto header wrap, which is expensive wrap, but it's the best. We also went with a long lasting copper reinforced connection donut instead of the factory graphite type. The graphite types tend to flake apart every time you remove them, ours can be removed and reinstalled multiple times if needed. This part isn't cheap but we used the highest quality materials and parts, and it's make in the USA. It's going to last forever.
The factory cross pipe is the main restriction in the oem cat back system so this pipe gives about 90% of the performance benefit of a typical full cat back system while retaining the ability to run the Record Monza exhaust, or anything else that connects to the stock mid pipe.
At this time this is only available for the manual transmission cars.
HI-FLOW CROSSPIPE (124 SPIDER/ABARTH)
Introducing the HI FLOW CROSS PIPE Exhaust piece for the 124 Spider and 124 Abarth, made and designed by EUROCOMPULSION. The biggest restriction in the 124 Abarth/124 Spider's cat back exhaust system is the factory cross pipe. The factory pipe pinches down in several spots to about 1 7/8 inches...

I bought my EuroCompulsion crossover pipe Friday Sep 18. Received it on Monday. Some posters have been concerned about the high price. Well, I’m a retired automotive research engineer. I used to do durability testing of 18 wheeler cat converters for my client FMC. We called the test “shake and bake” I ran those cats for days on a vibration table with exhaust so hot they glowed cherry red. I had several techs and two fantastic welders working for me. I used to buy the very best stainless steel for our test fixtures. That stuff wasn’t cheap 14 years ago. What I see in this pipe from EC is first class work. Add in the heat wrap which appears to be like that used in my Sila titanium turbo blanket, and the stainless hardware, and I can understand the price.
I planned to have a local custom exhaust shop install the pipe because of all the reports I’d read of broken studs when installing Goodwin’s cross pipes.
I had my Abarth in for alignment tweaking Monday PM at my Go-To guys, Yoi Kazoku, drift car specialists in San Antonio. (No, I don’t drift, but these guys know modified cars and they listen to what grandmother wants them to do.)
I mentioned my plans for the cross pipe to the owner, Justin. He said “if you bring it back in an hour, we can knock it out for you.” I mentioned that studs often break and he insisted they could take care of it. Well, I went back at 5:30, at 6:30 they snapped off the studs. They didn’t want to use a torch on the nuts because there’s a turbo line close by. It was too late to continue so they shot lots of PB Blaster on the studs, closed the shop, and TJ gave me a ride home in his truck.
Tuesday noon they told me the car was all set. The broken studs came out easily that morning. They bolted the pipe to the cat instead of using studs again. The rest of the hookup was simple.
The exhaust is now a little louder, about 2 decibels more at 3,000 rpm, measured using a sound meter app on my phone. I know you all want to know about performance gains. My butt dyno says it was worth the $500. The car pulls even stronger now from 3,200 RPM on up than it did before the pipe, and it was pulling much better than stock before. Seems to be spooling up faster. I still have a Y-pipe to install in place of the muffler. Hope to get to that on Wed-Thur. I don’t plan to spend my bucks on dyno runs for the car (I’ve been quoted $150 for 3 runs). I may do some 0-60 times with a data logger I can connect to the OBDII reader. Need to find a safe place to do that.
Thanks, Greg. I didn't want to go the total replacement route. With this setup, I can easily swap the stock muffler and the resonated Y-pipe back and forth as I want to. Might even want a Record Monza some day, and I still get most of the potential performance gains.
