Hello,

Well I ordered the throttle body spacer, and well i thought maybe add a Jpipe with it. There are many options available for the Jpipe.

I was leaning towards the Longtube Jpipe which removes the 3rd cat, but my concern is I live in Canada and every 2 years we must bring our cars in for a emission test. If I delete the 3rd cat will my car fail the emission test?

Any Canadians on here that have the Jpipe Longtube or Jpipe with a test pipe and passed emission test

2009 Sh AWD

Thanks In Advance

there are three cats.

2 primaries and a third.
the 2 primaries take care of emissions, while the third is there to raise the car to a ULEV rating.
in comparison; a honda civic is LEV.

The third cat is not monitored, it's used for NOx, there for it won't set a chek engine light. Your two primary cats are monitored by the primary air fuel sensor and secondary heated o2 sensor. Yes there is a difference between an air fuel sensor and hO2 sensor. Not sure how Canada does their emissions, if it's through the obd2 connector, or tail pipe, either or the xlr8 is available with out the 3rd cat delete, if emissions isn't a visual/tail pipe emissions then you'll be fine with out a 3rd cat.

Thanks for the great information, Well when you go for your emission test they do stick a probe in the tail pipe and do a idle test and drive test. I am not to sure what the numbers are.

^^^Not usually unless its and old car.
You have a 2009 Acura I think youll be fine

If they stick a probe in the tail pipe for measurements, then it's gonna fail emission test, because NOx content is one of the gases they'll test.

Answer is likely yes, you'll fail. You could do HFPCs and likely be just fine. You could also do the J pipe, and just put your stock back on to do the test - remove/reinstall can be done in an hour if not less.

Like Pseudo said, put the 3rd cat back on just before you go to do the emission test.

Thought it was against the law to tamper with/alter "cats"?

We offer a j-pipe that does not delete the third cat and therefore does not alter emissions.

Lol, it's also the law to drive the speed limit. I would do some research on your emissions testing facilities before you start altering your car. With the Xlr8 j pipe you can still keep your 3rd cat and get some extra power though. You could also purchase their test pipe and swap it right before your emissions test is due.

Not to rain on your parade but just so you know removing your cats is a HUGE environmental fine and you will have your car impounded! At least in Canada... I remember a few years back at Wasaga Beach the MTO had a sniffer bus set up stopping random cars for emissions violations and I watched a car get towed away!
Also you'll most likely fail your e-test every couple years.

Unless your racing the car and need that last couple HP to win the race and pay the bills it's just not worth it... WAY to many down sides and I didn't even mention the environmental issues in case you cared that one's a no brainer.

Your best compromise is to install the J-pipe with the High Flowing Cat and you might be down 1HP vs no cat but you're legal and can sleep at night.

Now with that said does anyone have any sound files of the jpipe with HFC and stock exhaust?

Thanks

Don't waste your money on the jpipe and hfc if you're not going to do exhaust. You'll feel no major difference in power.

if you remove the 3rd cat you will fail emission (most probably) since Calif is strict on emissions....

i would stick with jpipes that do not delete the 3rd cat....

Osman.S

Thanks for all the information, you recommended not going with the Jpipe unless I do full exhaust? I wasn’t looking to add a full exhaust system. I just figured with the SRI and P2R spacer it would add a little extra grunt or even a little extra sound.

The j-pipe will add power regardless of whether you do an exhaust or not. Of course every part you install that flows more exhaust will be an improvement but you do not need to do an exhaust to see gains from the j-pipe.

3rdGenHybrid

^^^^^ correct, the j pipe is probably the best bang for the buck... Even in Canadian currency, lol. You'll feel good bottom end power instantly.

I'll repeat; on the 4G - DON'T WASTE YOUR MONEY on the J-Pipe if you're not going to do an exhaust. It's like buying a Ferarri, and then never driving it over 35. Sure, it's great, but you're not really seeing any of the potential.

^^^ i honestly have no clue why u stated the above.....did someone butt fuck you with the jpipe ???

jpipe shows gains over the powerband, there might be a law of speed limit, but there is not law of how quickly you get to the speed limit

again there are people who do performance mods and people who do aesthetic mods and people who do both....and the JPIPE is done by all 3 kinds of people....as it does not hurt warranty, does not change your exhaust tone, makes you quicker (read QUICKER !!!) and you will pass your state emissions and safety without a problem....

Seems a bit uncalled for, but I'll roll with it.

My previous statement seems rather self explanatory.

If you're bolting things on the car to go faster, you aren't bolting things on the car to go half faster, especially at the cost. This isn't the 3G, this is the 4G. The car doesn't respond to the mods in the same fashion. I bolted everything available on to the car and had major buyers remorse UNTIL I did the exhaust. I shared my experience about this. It's the nice sticky at the top of the performance section.

^^^ lol sorry....im head it went kinda funny.....

WOW i dont/didnt think the 4G was that different....

you mean the say the exhaust is that restrictive ? any dyno comparisions with just the stock jpipe/aftermarket jpipe ?
