I have stock exhaust but i have a jdm itr header on the way i heard the collector size is different then the normal USDM one what brands carry a J spec one and i am also currently running a stock exhaust system...

ALSO am i going to get a check engine light coming on because i wont be running the Cat and if so how do i elminate this problem

 

1.) a quality test pipe is the T1R JDM length resonated test pipe
it can be purchased here: http://www.aj-racing.com/catal...age=4

this is a good choice because it eliminates that "raspy" sound a normal straight pipe would produce

2.) you may get a check engine light, it all depends. one thing you could do is raise the o2 sensor using piece that threads into the test pipe and also has a thread that the o2 sensor screws into. i forgot what it is called its cheap to make though and can be done at your local hardware store, someone will chime in soon

 

IMO most sound the same and brand shouldn't be the deciding factor, after all it is just a section of straight pipe w/ 2 flanges. I have a cheap comptech replica w/ flanges that fit multiple size collectors. Been laying around the garage for months.
30 shipped and its yours. Has 2 o2 bungs welded in w/ covers.

 

heres the cheap 02 simulator method. i didnt write this but its a really good step by step with pictures.

You now need to drill out 1 of the non foulers using a 1/2" drill bit. When finished this is what it will look like.




o2 Sensor inserted in the modified non fouler


Second, unmodified non fouler now installed on modified non fouler, then threaded into the downpipe

i used an electronic 02 sim from "zip tech" i bought it from http://www.importparts.com like 5 years ago. i cant seem to find it on their siite at the moment.

 

^^^^thats it

 

How 'bout buying a cat with the appropriate flanges?

Do you really think 1-2 hp at best is worth spewing vastly more pollution into the air?

 

buy one of the latest carsound cats.. they're virtually unbreakable.. people run hundreds of hp with cats.. i'm certain you wo'nt know any difference running 160-170whp max

+1 and a WTFBBQX2.

But if you're on track, and looking to silence the exhaust a bit then the T1-R is a nice piece

thats loud no matter what

 

I'm running the T1R test pipe and its not raspy at all. However I will be putting my Vibrant high flow cat back on for next year when my car somes out of hiding since the difference in power isn't that noticable.

 

sorry to hijack thread. will the t1r exhaust fit w/ the usdm t1r exhuast fit into a usdm EM? and will it also fit jdm 4 1 header? thnx

 

yeah i just want a simple install cuz i have stock exhaust but jdm header i have a skunk 2 on the way but ihead i need to have it modified since the piping is diffenent sizes and will need to be modified

 

thanks for the pictures ive heard of this method before but when i ask how to do it ppl are unsure because they usually just pay to have shops deal with it

 

but isnt the collector size different from JDM and USDM itr headers?

USDM= 2" or 50.8mm USDM test pipe http://www.aj-racing.com/catal...age=2

JDM=2.5" or 63.5mm JDM test pipe http://www.aj-racing.com/catal...age=2

ive always been interested in how a nice header and test pipe would sound on a stock R catback

I don't if you'd consider the jdm 4-1 a "nice" header, but coupled with a test pipe, it's not raspy at all. At WOT, the engine still drowns out the exhaust.

Exactly..

Its not like your running FI where a Test pipe might net you a decent gain over a High Flow Cat, on the majority of NA setups (especially something as mild as your running) a test pipe only gives you 1-2whp at best over a good High Flow Cat like Carsound or IMCO

 

i didnt ask if you were interested though did i. yeah id say it is a nice header, nothing crazy, but nice. i know in the cabin itll be quiet as stock, but behind the car.

If you're running a stock header and stock exhaust then a straight pipe isn't worth the 1-2 hp IMO. A nice hi-flo will flow just fine and still function as a cat.

 

even without the cat, our cars still make less pollutants than others that are stock...

im looking into the t1r jdm test pipe...that will bolt up to my usdm b pipe correct? im also thinking of getting the t1r bpipe next year, that should bolt up to my itr muffler?

 

Omni power has what you need. 2.5 " collector, o2 bung, ajustable length and cocking for about 100 bucks. I have one on my type r swap and it bolts right up to the cat back.

I failed with a bad cat and passed with a good cat. Bad cat = no cat.

Which cars do our cars make less polutants than without the cat on our cars? I've never sat behind any stock, decent running cars and smelled exhaust fumes excluding diesel.
