Hi guys!

i need some help from the owners of a Apex GT exhaust for the RX7 TII S5 1987...

its not possible for me to import a Apex GT exhaust catback (i live in Austria, Europe), and so i want to built my own

so i need all dimensions you know about the Apex GT...

piping diameters, dimensions of the muffler, lenght, diameters etc., so ALL you know and ALL i need to build my own Apex GT exhaust

if its possible, it would be nice if you can do a simple drawing from the exhaust, so it would be better for me to understand!

i hope you can help me quick cause i don't can droive with my old exhaust on the streets... to much leaks

big thx in advance

PS: i'm sorry about my bad english, i hope you can understand what i need

 

If you still have intact exhaust, as a temporary solution try getting some cheap mufflers off a junked rx and running a midpipe to um...
or, I made my own midpipe... and my own little sealing thing so it would attach to the header. Then I hhave (right now stock) mufflers and its about as loud as I could drive on the street. But it works if its the only option.
OR.. i got a set of stock piping (2 pre-cats a cat and mufflers) if you want um?

 

hi!

thx 4 your offer, but the whole exhaust system is damaged...

and 'cause the exhaust emissions law's in my fu**ing country a midpipe is impossiple...

i will make a costum downpipe, change the Catalyst with a racing cat and construct my own GT catback...

the friend of my sister works at a company which build exhaust systems and construct prototyps... so he can build any exhaust system i want...

and i don't want any other mufflers, because i'm in love with the apex mufflers
and with his help it will be possible to pass the volume tests...
