This isn't an issue with Subarus. The hangers alone give enough wiggle room. Most people run full 3" exhausts with no flex portions in them at all just fine.it can be done but this will create new exhaust leaks else where cause the exhaust system needs a place to flex and that's where it is![]()
So this SPT catback is cheap and not good because it doesn't have a flex portion in the midpipe?and that's how you can tell a cheap aftermaket exhaust system is they usaully don't have a flex section
