Quick review : Megan racing muffler

So I installed my Megan racing muffler today, ( TI-tips ) Over all the muffler looks good, well made and the tips look great ! ( pics to come )

The muffler is quite a bit lighter than the stock monster ( did the removal and install alone ) The Megan muffler is still not extremely light ( around 30 lbs ).


First thoughts :

The install went smoothly, everything lined up and bolted up without much of a fight. I ended up using the old bolts as they are longer than the ones provided and allowed much more of the nut to thread on.

The finished product leaves the tips pointing downward a bit so I'll have to see what I can do to lift them up a bit ( maybe loosen the hangars a bit? )


Sound :

Initial start up I was quite please with the grunt...Low rpm movement is deep...and sounds like a fart can honda. However, at higher rpm and full throttle it sounds amazing soon as the bit of rasp kicks in and reminds you that your driving an M3 and not an Integra.


Finishing :

The low rpm note leaves you disappointed to say the least, I have to admit a little embarrassed..

Mid range - high rpm is great.

Keep in mind there is likely some " breaking in " that needs to be done and also the rest of the exhaust is STOCK. I am praying that with the addition of my AP headers this will help the low end exhaust note a bit.. really praying.

Get an AR20 welded in section one. No more rasp.

I've had mine for a few months and I have noticed a change in the low rpms note over time. And yes, very impressed with the highs.

Get some ar20 or rasp killer installed. It kills the fart can sound and makes it sound nice and deep. I bought the whole cat back. Removed section two and using OEM. Perfect setup. I love the sound. As for fitment my tips point downward as well. If u can make it look straight provide instruction on what you did. I tried and could not get it to point level. Its a great exhaust for the money. Its an AP racing clone. Heard they are made in the same factory and just have a different name put on the tips.

The only trouble is I love the raspy sound. I'll see how it sounds with the headers and go from there.

AFAIK, Megan Racing's stuff is not made at any of the major brand factories, but that is the story for everyone of their products it seems.

I installed mine two weekends ago as well. Exact same complaints with low rpm sound. So I ordered a Modbargains rasp eliminator section. I will post before and after vids of that once I get it.

Quick update. If someone wants a video, I will see what I can do about uploading one here. Never done it before so it could be a new learning experience. So I installed the Rogue Engineering rasp eliminators. I am happy to say they were about 90% successful in eliminating the rasp and about 95% successful in eliminating that fart sound. I am very happy with the sound quality and sound level now....

FYI, the rear 6 bolts on this pipe section were completely rusted and seized. I had to cut them off witha cutting wheel and get new bolts in there. In case someone else is looking to get into this project soon.
