A silicone tb connection with a t-bolt clamp makes a better and tighter seal.

O-ring on my ish is holding just fine

AND an O-ring gasket wouldn't be a difficult part to find a higher quality gasket. If the ER CP was such a flawed design (or other similar TB-connection designs like the AA or BMS CPs), then explain to me why it's being used on several very-high HP + purpose built track cars

Any other input on this? Is it possible/easy to modify it so it will work with meth?

This charge pipe has worked great for me after I modified it. The sensor hole was just a tad too small so I made it a little larger where the sensor slides in snug. The meth bung they use is too tall so I shaved it down and re tapped it. I also purchased the right size couplers since the ones provided are a standard 3" which don't fit.

My lease is up in a month and I'll be posting it for sale. I had it painted in a wrinkle finish to have and OEM look. You can't tell the car has a charge pipe unless you know what your looking for.

The ER / Factory C-clip design is the superior mounting method over the generic silicone coupler. We've had several customers switch out their charge pipes with the silicone couplers for the ER one due to leaks and popping off. The BMS charge pipe also uses the C-clip connector.

Silicone couplers will eventually blow off- source: many turbo cars. They are more easily produced and allow for greater design slop, while the C-clip ones will always fit and are held on by more than static friction.
