CHAPTER 4: Lola The Fart Monster

CHAPTER 4: Lola The Fart Monster

After paying all that money, Turtle asked his mechanic to give Lola just a simple exhaust. In addition to the TRD 4-2-1 header, he wanted a high-flow catalytic converter and just a normal muffler. Something not too loud. Something that wouldn't attract attention. Shiny mufflers weren't of Turtle's preference. Pulling off a can from a Camry and spraying it black was perfectly fine as far as he was concerned.

When Turtle got Lola back from her engine rebuild, he tried to do one High RPM run. When the RPMs hit over 3500, an ubsurdly loud, disgusting fart bellowed from deep within Lola's bowels!



Effing gross! Effing embarrassing! Every single time Lola would be in the higher RPMs, she would make this noise.



Upon further inspection, Turtle found that in addition to the header and the cat, there was a magnaflow muffler.












Turtle didn't understand why it sounded so bad. Was it because of the 2.25 inch piping he had requested? Was it because of the header? It turns out that it was neither. It was because the magnaflow, a straight-through design, just wasn't enough to muffle the exhaust noise. Turtle found on the interweb that lots of exhaust systems require a resonator to help absorb some of the sound before it hits the muffler itself.

So turtle set out to find a resonator. Turtle looked into glass packs, which he heard made the sound louder in some cases. He then found two suitable candidates. A magnaflow thin muffler and a dynomax bullet-style muffler. Turtle went with the dynomax and had it welded at a place called Golden Muffler in Daly City.





At this point the exhaust note was great. Lola was still a little loud, but sounded aggressive and most importantly, no longer farted at high RPMs.

However, another thing that Turtle also couldn't live with was the fact that whoever did the exhaust work decided to add a long ugly tip that looked like a dong.



This gave Turtle a reason to go with a different muffler. Turtle used a brand called BORLA on Lana back in the day and he loved the way it sounded. So back on the interweb he went and he bought a new BORLA for less than $100. After sanding it and painting it black, Turtle went back to Golden Muffler, where their method of quoting is very simple and their service is quick, well, depending on what time of day one goes.








So now, we have the TRD 4-2-1, the high-flow cat, the dynomax bullet and the BORLA.








Turtle was extremely happy with this setup, but as time went by, his tastes changed. Turtle became more interested in keeping the exhaust legal, so he pulled out his old exhaust manifold, smartly kept from the rebuild, and sought a downpipe. Once obtained, he pulled a catalytic from an old friend called the Turbo Truck and he cut off the TRD header by the high-flow cat. Back again to Golden Muffler to have a flange welded and now we have the current setup.
Stock manifold, downpipe, large stock cat, dynomax bullet, BORLA muffler, and no tip. Another thing to note is that all the way up to this point, the entire exhaust system was one welded-together piece from header to muffler. Not a single flange. With the re-introduction of the exhaust manifold, the system is finally in manageable flanged pieces.



As much as Turtle would like to run headers, He's perfectly content with the manifold. Based on what he could hear, the manifold sounds less efficient. There's a seemingly cheap or hollow sound coming from the exhaust with the manifold, but other than that, if there is a drop in horsepower, the difference is minute.
Sometime down the line, Turtle would like to try his dream setup by running two borla oval mufflers, instead of the dynomax / borla combination, just to see if he could muffle the sound just a little more. but we'll see if this back-burner project will ever happen.

In its current state, Turtle is quite happy with his pieced-together-over-like-six-years setup. Now he can hear himself think. and sing.

  1. I had the same problem with a magnaflo on my 510. To raspy and loud at freeway speeds with 2.25" pipe all the way from the header.
    A 14" glasspack *intentionally installed backwards* fixed the sharp harsh sound right up.
