I'm switching back to a stock catback, I can't stand the noise on the car anymore, I got a Bosal OEM replacement b pipe and muffler, I just wanted to know if there is supposed to be two "squashed" sections on the b pipe, one before the resonator and one after the resonator. The one I got has two and I just wanted to know if it's supposed to be that way.
Thanks

 

its perfectly normal. all stock units have those awful squash sections.
