Washer Exhaust Scam!

newtothe370 · 09-11-2014, 10:18 PM

So long story short, after owning my Z for a month and doing research on forums like this one for many more months before that, I started to mod my Z, like anyone else would. My first mod choice was the exhaust. After seeing the hefty price tag on name brand test pipes, i took my *** to ebay and found a really good set for 110 with free shipping and hardware (the bolts were not the right size but a trip to home depot fixed that) (in total around 125). Basically, the test pipes are great and i love the raw gas smell but it has a raspy tone to it. Im trying to conserve my funds since i am a college student so I decided to fix my exhaust woes and try the washer method. I took off the gasket from y-pipe, put ONE washer on each side (not the recommended 4 lol) and refitted the pipe on. I didn't even drive a quarter-mile and I made a u-turn and went back to get the washer off. I lost nearly all my back pressure and my 0-60 felt 2 seconds longer. ALSO, the noise is incredibly loud! if you really want attention and don't care about performance than these mods are for you.

I never tried the washer mod with the stock cats on, but in my experience, with test pipes this is a must avoid mod. if you like back pressure this mod is not for you. I learned the hard way its better to throw a hefty chunk of change to get something good rather then find a quick and cheap solution which never works out how you want it too.

You probably already knew this but i blew 30 bucks and a hour trying this mod out so i had a bit of rage built up when it came out louder than a straight piped diesel truck and WAY slower than i was expecting, considering it was a 1cm leak in my exhaust.

The washers should be placed between the rear muffler and mid pipes, not the Y pipe. Also, it's not a scam. No one promised more power, just more noise. A scam would imply that you were cheated some how. I think the only thing that was cheated was your car with these cheap mods.

As per aszyd, the washers should go at the muffler inlets, not the y-pipe. That said, I do not recommend the washer mod as it will blow hot gasses at the rear wheel speed sensors wiring. I tried it for a short period, liked the sound, then had some tees fabricated with orifice plates to regulate the sound and curved exhaust tips to direct the hot gasses toward the ground. Redneck Engineering at it's finest.

It worked very well and was fairly cheap (IIRC, ~$150 for parts, welding, and cutting the exhaust pipes to make room for the tees), but, in hindsight, I think I would have been better off spending more and getting a louder exhaust.

WARNING: Putting holes in the exhaust system can allow exhaust gasses into the cabin. With a properly tuned/maintained modern engine and catalytic converter, that shouldn't be a problem (but it could be). If your engine is running rich and/or you have test tubes, it could be deadly.
