Just installed my fabspeed bypass pipes this weekend. They sound great, The idle is a little louder, but when you floor the car it sounds like it should. Nice investment, $ 570 and took about two hours to install. I did it myself on Friday night.

I have been considering the bypass pipes for some time but being in the UK
would need to fit myself
what problems did you have fitting and are any specialist tools required and what have you done with the old cats?

How is the change in power with the air filters and bypass pipes?

On my S I noticed a great difference in pick up, cures most of the hesitation issue. Never did get on a dyno but you can feel it, quite noticable.

It was a very easy install, no special tools needed. WD-40, some wrenches, a couple sockets, and ramps for the front wheels. If you want more detail let me know rob@conceptualkitchens.com

I wouldn't say it was an easy install. You'll have to be a contortionist to unbolt the right cat. To make access of the right cat easier, you'll need to remove the plastic underliner.

Once you've got both cats off, the install is straight forward. The trick is to place the new bolts/nuts strategically in the direction where you can easily access the nut. This means that 2 out of three will have the nuts on one side and the other has the nuts facing the other side. Unlike the stock cats where all the nuts are facing upwards.

The sound is not anonyingly loud at idle. In fact, it sounds almost the same. But oh, once you get on the gas! No resonance at highway speeds either. You'll only notice the music on the gas.


Really helps if you have an air rachet. Took me .5 hours for the left and 1 hour for the right. You'll need extensions to unbolt the nuts on the right cats. The nuts are way up in the well.

How does this effect emissions tests?

The second O2 sensor is in back of the first CAT so you get no dashboard warnings , FABSPEED did tests and it passed emissions, I went there and saw the results. I was told that the second cat was more for sound control and less for emissions others will dispute this.

Sound Effects

it should not effect emissions because there are two sets of cats, the second set, which you will remove, are just to make the car quiet.

if you unbolt all the mounting brackets, loosen the couplers, and remove the two bolts per side on the cat mounting flange, you can move the cat arount to get at the blind nut, the cat is mounted to flex pipe that will move.

I think the pipes make a more significant sound difference in the S vs the turbo since turbos tend to quiet things down. Any comments? Experiences?

I did this as well. That was the only way I can get to the cats. Glad you brought it up.

Just had the bypass pipes and BMC filters installed. The sound is much better and most of the hesitation is gone. Overall, a good investment. Todd @ EVO is working on a supercharger package for the "S". Should be interesting...
