flowmaster super 40... FE impact?

[PaleMelanesian]

If you run all day long at Wide Open Throttle, it might help a tiny bit. In real world driving, it usually doesn't. It might actually hurt engine efficiency. And then there's the temptation to floor it, just to hear that sound.

I wouldn't do it.

I a previous life, I put dual Flowmasters on my Suburban. The started rusting within a year. I live in Texas, where there is no salt on the roads. They're not the best quality. I then moved on to the Cherry Bombs. Sounded amazing. Neither did anything for mileage, though. That's when I traded it in for a Civic.

"Return on investment"???

Well, if you start with the assumption that they do improve mileage...

Aero Turbine

everyone we/I ever installed people loved them, with claims of improved FE also

for more subtle sound, Magnaflow is a nice muffler too

Performance Exhaust Maryland -- MBS is your Maryland source for custom performance exhaust

That has been researched, looked at, hashed over, re-hashed over, re-re-hash-hashed over, not to mention done to death, and it just plain doesn't work that way.

'zactly. I totally agree with you. I guess my e-subtlety () was too subtle.

Frank and PaleMelanesian are completely right. You won't see any improvement in FE from replacing your muffler. Your car will just be louder, thats all.

I got it~ I just wanted to use my new dead horse gif! LOL

[PaleMelanesian]

I'll have to save that one for later. So many times it can be useful!

yeah i didnt expect any FE gain from just the muffler, but what about an entire new exhaust system... like from the headers back.? or is it again with the, if any, "immeasureable" gains if there are any and the definite debate in regards to there being gains at all.
