Exhaust ?s
 

I just bought a 87 rx7 turboII and it has some mods on it my question is has anyone ever seen a thermal research exhaust on these cars it had one when i bought it im not complaining at all i love their exhausts but ive been trying to research it and i cant find any information about it it has a 4" runner and dumps to 3" Y to the tail pipes its a really sick exhaust and sounds really good if u guys have any information i would really appreciate it Chris

no info or opinions on a thermal research exhaust on and rx7 im just wondering cause i havent been able to find it

I too am wondering about TR. They have always been highly recommended in the Honda and Nissan communities, but I have never heard of anything about Mazdas.

yeah its kinda weird i cant find anything about it however my 87 turbo II has a full turbo back on it and i checked all the pipes its not just the mufflers all the piping is high quality bends and extremely clean welds at the flanges so it really looks like thermal research to me I have one of their exhausts on my 91 integra so im familiar with their type of designs
