Best downpipe for my 2006 R - opinions/recommendations?

[Mr R!]

Not this summer. We were planning to drive to Norway next May for the Constitution festival. We hear it's a great time. We have not figured out a route yet.

Come on!!!

There is no scientific proof that running a high-flow cat is any less beneficial than no cat.....at least i don't have a headache from noxious fumes.

The TME downpipes rocks! Swedish quality all the way!!

I've got one and it is nice. Since you are local to TME I'd say go with them, screw the OBX China crap, support your local business

What are you talking about.... Granted it's not a huge difference, but there absolutely is scientific evidence of this. It's called flow. If something obstructs flow of something, it slows it down, end of story. Put a paper towel over a fan and see if it puts out the same amount of air.

Enjoy your 1hp gain, over removal of a 49state legal High-Flow Cat, as well as a stinky, pollution prone exhaust. I'll keep mine in to pass inspection and avoid fines.

But I like seeing flames fart out the exhaust

In all honesty I agree with you. Running CATless is not cool nor seriously beneficial.

I haven't gotten any fines, and always pass inspection.

You wouldn't in Cali.

Wait... WHAT!?! Can I fart flames from my R's exhaust now? I must do this

[Vio-TT-R]

In all honesty, I don't mind cat-less. I ran that way for like a week, but the headache that I kept getting from driving and 2 minute waiting periods at lights just proved to me how noxious the fumes are.

Yeah broseph! Flames are always fun!

[R.Photo]

The fumes are annoying, occasionally I smell them, but I'm VT where I'm usually not waiting in traffic. I originally bought a hi flow cat that I planned on having installed, but couldn't bring myself to do it before I got a flame throwing photo(which I haven't taken yet)

[MountainR]

At what point am i going to throw hot fire from my R's butt???

Floor it then let off the gas abruptly allowing for unburnt fuel to dump into the exhaust hopefully igniting from the hot exhaust pipes.

Hmmm... must try this soon.

The orginal emmission , not tuned car,can not handle a catless downpipe right!
The cat and the engine are like made to work as one!

[R.Photo]

You hear a loud backfire, I haven't seen if I shoot flames yet, but I don't know why I wouldn't.

Not sure at all what this means? Are you referring to O2 sensors being out of whack? O2 spacer FTW....

This sounds conservative...what happened?

omg you did not just put a human centipede photo up....groooosss

Hello!
I thought that the two lambda probes measure the exhaust value before and after the
catalyst (the racecat) and
If you now remove the catalyst and driving without it will of course no correct values ​​as the engine and exhaust are set from the original.
They both probes know no longer what they should do!
The fuel consumption is increased and the loss of engine power output.

[dave_n_ruth]

It just seems to trip the check engine light. The spacer is used to stop the error from occurring. No one has noticed anything other than that.

[300+_T5R_855]

I thought CJ made the IPD DPs out in Cali?

I do make the S60R down pipes for IPD. Made in the US with American Stainless. The materials I use cost me more not including the catalytic converter than the OBX down pipe. The catalytic converter I use is a 3 way 50 state legal cat. It is not legal by California's rules, but works as well or better than the OEM.

IPD makes a complete 850 exhaust that looks like an OBX, but I was told it is not made in China, but comes from Canada to their specs.

Spacer!? Whats that!??

[jclough]

It's true. Not many original owners remaining on here.

I'm an original owner! And I paid slightly more than you did.

[dave_n_ruth]

Well don't you feel like a fool? Now people are buying these things for $12k and ricen em' out. There was a time when the meer mention of chrome pegs would get you flamed out of the forum.

[850arrrsaylikepirate]

Spacer!? Whats that!??

It's exactly that, a spacer that goes on the end of the rear O2 sensor. It fools the sensor into reading a different value and thereby not throwing a code.

Fuel trims, and mixtures aren't controlled by the rear sensor so it's ok to space it.

Another option is, if you have a tune from RICA or AutoTech is to ask for them to delete out the rear sensor so you never see the check engine light.

cannot wait for the 3rd installment, its supposed to be really gross!

Anyone done a sound comparison between the TME and the Elevate DP?

I am considering a DP with my TME Exhaust, I am impressed with the build quality of the Elevate but at the same time I am also thinking a conplete TME (DP+Exhaust) may be a better option in terms of compatibility.

Elevate claims that they have the largest Cat in the market and also that their DP is quieter due to the larger size.

Any advice?

[dave_n_ruth]

DP doesn't add much noise. Increases the growl under WOT, which is awesome. Don't base your buy on that.
