Hi so my buddy told me about a shop that sells aftermarket parts so I went to check it out. When I got there I saw they had a sale on tsudo n1 style mufflers. My car does need a new muffler but I just don't know if I should get them now or just wait? My car is NA S4 86 pretty much stock. Just wondering if any of you have heard of this brand or have advice about free flowing exhaust on S4 NAs. Thanks!

 

It's an ebay brand that takes the same enthusiasm about quality and fitment as OBShit (OBX). Racing beat makes a nice exhaust that looks stock and sounds good. Seems like what you might be looking for.

 

you cant go wrong with rockauto Bosal oem replacements. with an RB header, I get a nice idle, and a nice WOT

 

Go to the Mazdatrix site and read their narrative writeup concerning RX7 Exhaust. They call the heat generated by RX7's "impressive". Basically, cheap aftermarket mufflers will be totally scorched by RX7 exhaust heat in a short period of time. Make sure whatever muffler you get is designed for use in RX7's.
