What's in the Box
Dec 2, 2024
Review shared from Flowmaster Force II Crossmember-Back Exhaust System (74-79 350 V8 Corvette C3)
Good System, but was slightly damaged
The system overall is very nice, good sound and overall good quality construction from Flowmaster. But one of the exhaust tips was bent a little bit, probably from shipping. Wasn't enough to warrant a return but it was a little disappointing.
5 Top Rated Questions
Q: the lower alternator bracket bolts into the stock exhaust. Is there a similar threaded hole on the headers
A: No bolt holes in headers for the alternator bracket. Will require using item EK-25-102906-1 Corvette Alternator Bracket Small Block Lower With Headers.
