TP, for that wholesome 4 banger raspy sound.


And the flame shooting out the exhaust comments from stunned spectators.

"holy **** its a mitsu jet"

Driving with the test pipe all the time is not worth the potential fines IMHO for the minimal gains for the street.
I'm right there with you. IMHO, a test pipe isn't worth the hassle unless for a track day, or for a big event where race fuel is being used.

I hate the smell, and making others behind me (where cars in general usually are ) smell nasty pollutants. Now I'm no Global Warming activist, but the risk of ticket + smell + environmental smellyness is not worth the minimal gains.

I use the Perrin HFC and have had great luck with it on my bolt-on application.

I can't vote in the poll because although I currently run a test pipe, I need a HFC ASAP to compete in STU class SCCCA racing.
If anyone has a HFC they don't want, or wants to trade for a test pipe, PM me.

I guess I run a test pipe even though the DC sport DP eliminates the cat section of the exhaust. But we don't have emissions they just check the ECU for CEL codes they are supposed to do a visual inspection but they don't

I think this pretty much covers it:

WHAT YOU SHOULD KNOW ABOUT USING, INSTALLING, OR BUYING AFTERMARKET CATALYTIC CONVERTERS

As of January1, 1988, all persons engaged in the business of automotive service and repair, as well as other parties named in section 203(a)(3) of the Clean Air Act*, are prohibited from installing or selling aftermarket catalytic converters which have not met the criteria of EPA's interim enforcement policy entitled 'Sale and Use of Aftermarket Catalytic Converters'* (published on August 5, 1986). The installation of non-complying converters by a named party will be considered a violation of section 203(a)(3) of the Clean Air Act, and the violator may be subject to a civil penalty of up to $25,000 for each improper installation.

EPA's aftermarket converter policy also requires installers to maintain certain records pertaining to the aftermarket converters they install.

...

(1) Why are there special requirements for aftermarket converters?
...
(2) When did the requirements take effect?
...
(3) How do aftermarket converters differ?
...
(4) How can I tell if an aftermarket converter meets EPA requirements?
...
(5) What about using converters from salvage yards or junked cars?
...
(6) When can I install an aftermarket converter?
...
(7) In general, what are the requirements for manufacturers?
...
(8) What are the requirements for installers?
...
(9) What should customers know about buying converters for their cars?
...
(10) How do I determine the correct converter for a car or truck?
...
(11) What may happen if I don't use the correct converter?
First, it is a violation of Federal law because it is likely to increase the amount of pollution coming out of the vehicle. Penalties for violations by individuals, service or repair shops or fleet operators are up to $2,500 per violation. (Each improper installation is considered a violation.) New car dealers can be penalized up to $25,000 per violation. Any person who causes a violation could be subject to the same penalty as the installer.
Ya places yer bet and takes yer chances.

Straight pipe or nothing! I just am so damn addicted to the sound and performance of it. Running a test pipe is much better for me.

If that looks clogged to you, please don't ever look at a ceramic based catalyst, or a metallic cat with more that 100 cells per inch.

The cat in Roberto's Evo is the MIL.SPEC 100 cell cat. It is the highest flowing cat on the market. Metal catalysts are more resistant to heat and light off quicker than ceramic units. On top of that, the cores and housing in the MIL.SPEC cats are all made in the USA. Some other companies use less expensive Chinese made units with inferior PGM coatings.
