HT-Spec TSX Gets An Exhaust System from Fastline Performance and Fujitsubo

Coming off last week’s debacle of having the rear glass in the TSX shattered (which incidentally is not fixed yet) I thought I would look back at two of the most significant upgrades done to date on the car.

First off, I must highlight the exhaust upgrades that have been made so far. The addition of a Fastline Performance (FLP) Open Track Pipe and a Fujitusbo Legalis-R Cat-Back have added a new dimension of performance and style. The first performance mod I did to the TSX was the 2.5″ FLP test pipe. Before going on, I must warn you that it is illegal to remove a functioning catalytic converter from any car in the USA. This is true even if the intent is to install another functioning converter! In the state of California, it is only legal to install a converter on a car that is specifically certified for that car. In other words, FLP cat- and track- pipes are intended for track or racing use only!

Fastline Performance Open Track Pipe

2.5" Open Track Pipe. Mega-high flow and a built-in CEL Eliminator provide worry-free power gains.

FLP pipes come in straight, open test pipe, resonated test pipe, and metal-cat versions. Also, all pipes are available in your choice of 2.25″ or 2.5″ diameters. Usually people like to match their cat pipe diameter with their exhaust or header. We accommodate this demand however strongly urge people to choose 2.5″ diameters in all cases. Truthfully the only reason to go with a smaller pipe is to limit the power you will ultimately get. Don’t let your anal-side take over…in this case, BIGGER IS BETTER.

FLP Open Track Pipes come with pre-installed heat-shield tabs for a stealthy look. They also come with super-high-end laser-cut flanges for a leak-free install WITHOUT GASKETS.

Test pipe installed?

One drawback that I have noticed with the deletion of the converter is definitely a distinct, environment-damaging waft of emissions coming out the tail-pipe. To alleviate this guilt inducing stink, we’d recommend installing a Fastline Performance Metal Cat instead. It has most of the cleansing qualities of an OEM converter which kills the smell, but gives up no performance to it’s wide-open siblings. Just don’t count on it passing a tail-pipe emissions test.

My intention was to do some dyno testing with these cat-pipes, because I know for a fact they make significant power. I also wanted to do some sound testing with them as well to alleviate concerns people have about noise. The best I can do at the moment is say, I definitely felt the car had more kick coming off turns, and the sound changed so mildly that it actually added an aggressive growl that should have come stock on the car!

Another common misconception regarding FLP pipes, particularly on the TSX, is that they are less effective on 06-08 models which come with a so-called “high-flow” converter form the factory. While it is true that the 06-08 converters flow more exhaust than a 04-05 model converter, it is completely untrue to say that there isn’t a gain to be had on those cars. In fact our first prototype car for the metal cat was a 5AT 2006 model, where the test-fitter was very pleased with the performance gained! If you have an 04-05, don’t get suckered into buying a used 06-08 cat that will only provide an imperceptible gain, and if you have an 06-08 don’t think an FLP cat pipe isn’t a worthwhile upgrade!

With the converter happily in place, and the Eibach 2010 meet quickly approaching, the HT-Spec TSX was still without an exhaust system. In the weeks closing in on the event, imagine my surprise when my family, led by my wife, presented a Fujitusbo Legalis-R Cat-Back exhaust system on my birthday!

Legalis R Mufflers.

The Legalis R by Fujitsubo is truly a special part. The pipes are made of the most luminescent polished stainless steel, from cat to tip, built up with perfectly tuned resonators to produce a melodious sound that is both prominent and understated. Artfully crafted hangers are carefully braced and gusseted to the pipes for a suspension that exudes engineering prowess. The perfectly-sized muffler tips are slash cut to provide just a hint of performance. But the system is always classy and never immature. Yes, it is a “tuner” exhaust…but for those with style.

Blah blah blah…we need pics!





Surly a system that looks this good can’t provide performance. I myself was guilty of the notion that the stock exhaust system would be difficult to improve upon in the area of efficiency. Imagine my pleasant surprise as the HT-Spec TSX pulled harder in each gear than it ever had before once the system was in place. Unlike most mods like this I have done, I really noticed a power gain the first drive I took.

I have rambled on about the Fujitusbo Legalis-R Cat-Back long enough. The superb combination of looks, fit, performance, sound, and status earns this exhaust an HT-Spec Certification!

    This exhaust sounds incredible! It has a nice low growl that is not overly intrusive or obnoxious. It was nice to hear it in person. Sounds like it makes some nice power gains too!
