Their stuff looks interesting and the price is right.

I wish their rectangular tips were larger and closer to the look of the factory LTx rectangular tips. The skinny chrome rectangles just never looked good to me.

I can't exactly tell but the system appears to be an X pipe then a pair of chambered muffler sections then right before the tailpipe itself there appear to be some mini bullet mufflers or resonator things?

Overall I am curious how loud the system is.

Also they don't spec the exhaust pipe diameter... I find the lack of their providing that kind of simple technical detail annoying... to say the least.

But the stuff looks neat, I would like to try it out.

Seriously doubt chambered exhaust would flow very well. THE PIPES AREN'T STRAIGHT AND SMOOTH!

Rubber weatherstrip (which is the other thing returning on a C4 search) is likely sourced from other common vendors. So....can't say I see anything interesting on their site.

I have one of their systems with the C6 tips in a box in my garage, Plan on installing it on my 93 in the next week. I'll report back. There are some Youtube clips from other guys on C4s.

Looks good!
looking forward to hearing your reports on sound, volume, and drone.

What diameter are the pipes?

Installed it today. Went together very nicely. Here’s a pic and video. Sorry for the dust! It sounds awesome driving it. Some drone but not a bad one at all, music to my ears driving! Now it sounds like a Corvette!
