So this car has a Muzzy exhaust on it.... and when I pulled it off the car as I was taking the engine out I noticed something rattling in the header tube.
Muzzy apparently installed some type of Center divider in the header and it looks like it came apart and just sitting inside banging around restricting the exhaust flow.
Anyone thinking of replacing their stock exhaust system on they're normally aspirated cars don't bother it's not worth the money
I've witnessed multiple Dyno pulls and in some cases lost power over the stock exhaust system
