FlowTech Purple Hornies Mufflers Reviews


Horniest turndown

Reviewed By Drake S (PRAIRIE DU CHIEN, WI) Reviewed for a 1974 Plymouth Roadrunner —9/5/2017 11:29 AM

Arrived quickly and in good order. Mounted easy on my flowtech ceramics. Have them on a mild 360 and they sound really nice not excessively loud, but they get some good attention.

Flowmaster Outlaw Muffler Reviews


Worth every dollar!!!

The best part is I got it for the cheapest price from here auto anything by $33. So I will be shopping here more and recommending all my car lover friends which is huge
