As said, everyone knows TTI has exhaust systems for Cs and we've seen many installed. So why does no one recommend Accurate ? There had to be a reason...
I think there's a couple reasons. None have to do with Accurate's quality or customer service.
For one, the C-body guys aren't into the "correctness" like the B and E body guys. We're happy to just get the parts and have them fit. Quite frankly, it's one of the reasons I like this crowd. I've never been into getting correct date coded parts and there's almost zero references to that level of restoration here. Having the right nuts on the hanger by the rear end might be important for the guy with the restored Hemi 'Cuda, but no one is going to climb under my old 300 to take a look.
The other is that the original C-body exhaust is pretty anemic. Quite often it was a single exhaust pipe or duals that had 2" tail pipes. A lot of guys, myself included, just can't bear to spend hard earned money on the stock pipes when the TTI stuff will offer a performance and mileage (at least in theory) gain for the same money and maintain an appearance that
most people will think is stock.
I understand the business decision to not service the C body community. The ratio shows total Mopar business against C-body business and not comparing to C-body to A-body or something that I would find more interesting though... But that's me.
The answer is pretty simple... Give this guy enough business to justify making some C-body pipes and I'll bet he will. Staying with the core business is good, especially if the resources are already stretched, but most business guys know to be flexible and keep an eye on opportunity, especially if the tooling and system knowledge already exists.
