the "I Like My Stock Exhaust" thread

[Blue_Demon]

Random question, but has anyone been thinking about the Roush rear valence and quad exhaust? I don't want the actual Roush exhaust, but I love the quad look. I was thinking about dual 3.5 inch tips on each side welded to the stock mufflers but I have no clue what it would look like with the Roush valence. From what I gather the actual Roush exhaust is 4 inch tips.

A good exhaust shop could make it work no granted you already have a premium bumper and the roush valence to test fit.

I am perfectly happy with the stock exhaust. I would love some good exhaust noise but this isn't the engine for that and every aftermarket exhaust sounds like poop IMO. Ford went to great lengths to quiet this car and I will enjoy the "sleeper exhaust". Money spent on one when I get a bigger motor

If someone can make 400/400 on stock exhaust save for a down pipe I'll keep my stock exhaust.

I did the Muffler delete and never looked back.

The delete gives just enough growl to be heard with the windows down but not enough to be distracting or obnoxious. I don't think this engine sounds particularly great, but the delete isn't a bad sound either. Plus I only spent about $50 haha

The main restriction will be necking down the DP from 3 inches to 2.5 to mate to The stock catback. The stock Catback is less restrictive than the stock DP but more restrictive than a true 3 inch.

Going to have to disagree with you also.... Have you seen the inside of a stock muffler? Looks like a maze from the movie maze runner lol. There's a thread on here where a guy opened up the stock resonator and stock mufflers and the stock mufflers look way worse than the resonator.

I can see why it looks like that to the untrained eye, somethings about flow dynamics are counter intuitive. the design of the stock mufflers and resonator are quite ingenious providing alot of resonance without restriction.

Mishimoto did some heavy research on this here

What they picked up by removing the resonator and the "restrictive" stock mufflers?

In our case, variances in power were negligible after opening up the CBE portion of the 2015 Mustang EcoBoost exhaust. We know the addition of a downpipe and tune results in huge power gains (see downpipe testing results here), but it seems as though the cat-back upgrade will be an upgrade for sound/aesthetics.

This was done on the stock downpipe. Now once you start increasing flow with a freer flowing downpipe, that might change because of the neck down- not the mufflers.

i like that tinted plate cover, where did you get that?

As promised. Really happy I went this route. Considered 4 inch tips but these fit just the way I wanted. Thanks for the tip [MENTION=13130]mtpavelka[/MENTION].. pun intended

I realize this is an old thread but am considering doing this tip "transplant".

Some questions:
1) Are these 3.5' outlet OD with 2.25" inlet pipe?

2) Were the exiting tips cut off flush with the muffler or was a short piece left?

3) Is the inlet of the new Vibrant tips sized to slip over 2.25" piping or must it be simply butted up and welded?

Appreciate any feedback on this........or other similar suggestions for tip replacements!

Wow, this might be the oldest ressurection of any thread in M6G history.

Inquiring minds want to know

Magnaflow, 2.5" inlet, 4" outlet, cut off the old, weld on the new.

Yes, I realize that.....and getting responses from prior posters is probably a long shot, but after a lot of searching, this thread contained info I was interested in.


Problem is that I really would like to improve the look of my exhaust outlets. This is one way to do it fairly inexpensively. Obviously the other way is an exhaust change, like an axle back replacement system. I am also considering that option but would only go that route if I could get a better sound, with little increase in volume while cruising easy but more "bark" only when I step on it. The only two systems that I might consider are: 1) AWE Touring axle-back and 2) Ford Performance by Borla Touring axle back. Of the dozens of exhaust system sound clips I have listened to so far, these two are the ones that interest me......but......clips and reviews of them are pretty limited…..and I'm not really sure I like the sound that much better than the quiet stock exhaust. I sure don't want my car to sound like a blatty ricer kiddie car!

So....I go back to considering just replacing the stock tips for now.

Wish I could find more feedback or actually hear those two axle back systems I mentioned....

Those Magnaflow tips look pretty darn good too, Chef! Big improvement over stock - do you happen to know the part number of those? Did you cut off old tips flush to muffler and simply weld new tips on?

Thanks!
