thanks guys, and @ben37s yeah i heard that the non resonated test pipes do have a bit of rasp right around 3k and some drone, but also I do not know of anyone who is running the setup of the ark grip catback with the fast intentions NRTP. I've read on Berks and HFC's paired with ark and people say Berk TP have a lot of rasp. Still undecided, kinda leaning towards the no and save up for HFC's side..lol.

 

1. I have fast intentions resonated test pipes and my CEL has never turned on. The non resonated will be the same as it uses the J-Bend o2 bung setup.
2. I am not sure about the rasp with the unresonated but I have no rasp. I get a lot of hiss in the morning when the gaskets haven't warmed up yet. With a catback you should be fine. I have the stock Y pipe and mid pipe and still no rasp, also no drone at all. Oddly enough I had more drone with my setup with the factory cats. I had the test pipes paired with an invidia catback for like a week and it sounded fine, just wasn't as loud as I wanted it so I ended up selling it.
3. I live in florida so no emissions here either. I am not sure about Chicago but in florida cops really won't bother you for exhaust noise or smells. Without a tune it does smell like fuel somewhat often. Once you have the tune it should be fine, I drive with the windows open a lot so I am smell it every now and then when the wind seems to blow in a specific direction. With the windows closed you won't smell it at all.

 

Perhaps I shouldn’t be surprised, but none of these latest comments refer the concept of doing the right thing, or am I that much out of touch? What about these pipes contributing to noise and air pollution? Isn’t that the reason for catalytic converters in the first place? No one seems to care about that. And what are we teaching our children about citizenship? It seems all that matters is what you can get away with.

 

i have a 4 maps from UpRev installed I always keep on map2 which is tune.

Dude ure going WAY off topic here I notice u comment on a lot of threads acting so goodie tooshoo U drive a "sports" car im sure u ripped a burnout or two and sped past speed limit. And who cares about a little pollution motorcycles do it everyday, Factories do it everyday, When u fart ur polluting geez guy

 

This is so wrong dude.

A few states that have strict emissions policies have very strict laws regarding removing cats. In CA cops do actually check if they pull you over and your car is obviously modded. Its a huge fine.

Some other states straight up take your car and impound it.

Look, I'm not saying don't go cat-less, I've done it in previous cars. Im saying don't go around touting the idea that its not illegal. It is FEDERALLY illegal. Period.

 

its really not a big deal. Unless ure revving all over the city drawing attention yea cops will check. Motorcycles run no cats some states dont bother with emissions some do just like u said, Scooters dont have cats, 2 strokes, my snowblower and leaf blower, i mean My two way VHF radios are illegal to operate without a FCC lic are they gonna come bust my door and fine me? Geez lol! But i get what ure saying. BTW i run cat'less on all my vehicles, Highly doubt feds gonna trace my IP and come knocking on my door we could go on and on about whats illegal whats not but the OP posted this for opinion on the test pipes and we're just trolling

 

Yes, and so are most intakes.

 

I just had my berks non resonated TP's put in monday. Driving normally, you can't even tell it has TP's. Maybe the car is a bit louder. But if i get on the gas there is a ton of rasp around 2.5k rpm all the way through about 3.5k. But after that it's more just overall loudness. I have had no CEL light, yet... And I don't care about the smell because all my friends have been catless ever since we started to mod our cars. So im used to the global warming smell. Personally, after my experience with my non resonated berks, I would only recommend HFC or something resonated for sure. But I've had people rev my car and do fly-bys while driving my car, the noise is alot worse inside the cabin than out.

 

agree on that. my rasp comes at about the same rpm as urs. When u floor it the monster screams and im im not even sure which berks i have. it has the o2 sensor tube thing like it bends towards the motor but every one i know loves the sound. Def louder in the cabin

 

I run resonated Megan test pipes. They have the O2 bung pushed outwards away from the exhaust flow but I still get a CEL. There is a noticeable amount of rasp over stock, but not terrible and I hardly notice it anymore. In fact I did a cold start up for a couple buddies of mine a few days ago and they actually liked the sound.

The exhaust smell is also quite noticeable outside of the car, but again, nothing that even remotely bothers me. The car seems to run a lot better with these pipes.

Eventually I want to get some Z1 gaskets with some RTV applied and see if that helps as the rasp at all.

 

yea my cel is on idk whats causing it. I bought it all done up and last owner said it was because one of the dc headers didnt come with a o2 sensor slot but one day while it was up on a lift all 4 sensors were there. Mechanic told me its because the pressure of the set up or whatever and not the sensors. Guessing its the TP but i like the sound

 

Justifying bad behavior by pointing out other bad behavior is a spurious argument. The topic here is illegal test pipes, regardless of how much you try to rationalize it.

 

OP, the Fast Intentions J-shaped O2 Sensor connector seems to do a fantastic job at spoofing the ECU, more so than other designs.

No, legality is your topic. That's not what this thread is about. Moreover, the OP very specifically asked for input from people who have FI exhaust components. That excludes you, Chekov, yet here you are whoring this kid's thread. Well, quit it. No one cares about your sanctimonious crap.

You do this in every discussion, like a cancer on this forum. Buy another car already.

 

Most mods we do to our cars are illegal. Most intakes, most exhausts, have your tires slightly stick outside the width of the car and no mudflaps? Illegal as well. I hate every time the topic of test pipes comes up and someone always has to complain that they're illegal, yet they run HFC, which are illegal too.

 

for real! That dude is in the wrong forum discussing how illegal such and such is for modding cars maybe he should join a neighborhood crime watch or something i saw him comment on about 3 threads already talking like this. Hard to believe he even owns a G37 coupe. People who like sports cars are people who likes aggressive things, fast stuff live a little more dangerous than others (proven statistic fact) and he doesnt fit that statistic just saying
