hey, since I couldn't find an RB catback anywhere I got the turbo one from mazdatrix.
They told me that the tips are sightly bigger but that it won't alter performance.
The system might also be too loud.
Will the RB turbo catback and a Bonez race pipe be too loud on my 89 GXL?

thanks

 

You know, i thought about doing the turbo mufflers, but thought it might be to loud...but i would love to see someone try it. I've allways wonderd about it.....CJ
