Corsa lists it as "Slip-on" but they never expanded it. They only cut the slots in. Seems like they're getting lazy. I'll snap a photo over the weekend. I took the stock exhaust off and installed a corsa and man... the rattles back even after a resonator. Debating if I should install another...
you can take it to a muffler shop and have them expand it. or purchase a expander on harbor freight to save some money. But be warned its a pain without a way to clamp down the resonator to keep it from spinning.
Damn I just took my bronco in to fix a crankshaft leak... took a damn week and a half and they wouldnt cover the rental car without a extra coverage I need to purchase.
Not again...
Its the corsa pro series resonator 2.5" (stock piping). One thing to note is its not bolt on ready if youre thinking of doing it yourself. The resonator needs to be expanded on both ends for the "slip fits" so the stock midpipe can slide in.
check that heat shield right on top of that magna flow. It rattles and could be a potential rattle from the vibrations. I shoved insulation there to keep it from rattling at high rpms. (slight rattle was there before downpipe install.
Great news. Just installed the corsa resonator 2.5” on my stock piping with stock exhaust and the rasp is gone! Tamed the throatiness from the down pipes too. If you’re getting rattle noises like I did, check the heat shields on the body and shove appropriate insulation material to prevent any...
damn i have the corsa resonator on the way to slap on my stock exhaust and this post killed me a little. Was hoping for that rasp to go away. Sounds like a civic fart can.
wouldnt the insert restrict airflow? defeating the purpose of the better flowing cats? im still on the stock exhaust so theres room in the mid pipe section to install a resonator.
