I got the muffler and pre muffler from Parts Off in japan for 8000 yen. about 100.00 It's a Tanabe Hyper Medalion exhaust system for a Nissan Cedric. The Japanese stainless was 3" inside diameter and the stateside stainless mandrel bends are 3" outside diameter. So a chop saw and a tig welder its now for a 1st gen 12at RX7.

Looks awesome!

 

You've been busy! No heatshield?

 

I ran the last one with no problems. I think they are mainly there for the cats those get really hot. There's no sound deadening material on my interior all the tar stuff is removed so really nothing to melt. Passenger comfort? They are lucky they get a seat. Lol

That and I just don't have any to put on...... I may get some stick on type but now not worried about it.

 

Ah, cool. My car doesn't have the big cat heat shield either. It has the rest though, and full carpet in front.

How loud do you think your whole system will be on a rotary? I bet you'll be surprised how much bass will come out of a 12A. Nice high volume oil pan, by the way.

 

I'm hoping for a nice bassy rumble while idling and probably an ear drum raping roar on throttle. Just as long as I don't sound like a fart cannon. Actually, the turbo is a good at muffling noise, so I'm hoping it sounds good and isn't cop attracting loud. I really don't want to run a silencer in the tailpipe.

Thanks, Got the oil pan off eBay about a year ago.
