Backwards Flowmaster
Hey all, I had some 2 chamber Flows put on my car today (I got the guy down to $200 for the mufflers and labor), but I noticed one of them is backwards! The inlet is facing the rear of the car. Some people have told me it will be a little more restrictive, but not much, some say, it won't make a difference, others say, it will upset everything.
At idle when I put my hand over each side (No tail pipes, exhaust is dumping straight out of the Flows) they seem to be blowing the same. I really don't notice a difference. Because of the circumstances, I really can't bring it back to the guy to redo, and if I did, the muffler would probably be too close to the driveshaft as the offset would now be the outlet instead of the inlet. Will this really make much of a difference? As it is now, the car is almost too loud. My friend can hear me blocks away. I also have the factory H-pipe if that means anything. Exhaust is 2 and 1/4 inch from manifolds to 2.5inch Flows. Thanks Chris Car is a 69 Mercury Cougar (Mustang with different skin) with 302. |

I don't know about other muffs, but a flow DOES matter which way it goes, Take alook of a pic of these things guts, and you'll see why. If the muff, is center in offset out, just flip it over.

You need to turn it around. Flowmasters are made to flow one way only. Is should sound different then the other.
