So basically my problem is ; i bought a Bosal Exhaust from Advance auto parts that looks like this . I can't seem to snake the muffler through since it's in one piece, i'm wondering if i have to dismantle the rear suspension, which seems like a lot of work to do to install an exhaust system. Please, if you have any knowledge or help, let me know! p.s this is my first z car, and the first car i've done manual repairs on, so i'm in the dark about a lot of things.
