Well, I'm not too far away from getting my exhaust system sorted.

I have decided on BATMBL's twin dumps, + large Catco cat @ $720.

Just not sure on the cat back, I am thinking of getting a custom job done

by Jack Beedhams but am worried about noise.

I am thinking of removing the middle muffler, getting new 3inch mild steel

maundrel bent pipe work, no resonator and keeping the stock rear muffler.

But I guess that won't be large enough, ie the stock inlet would not be 3 inches =

restrictive...

Does anymody know the brand that CES Racing uses? I know it's a SS twin tip

muffler but can't seem to google it with much success.

Also will this be legal noise? Perhaps even a good AM twin tip would not be enough

and I will need the 2nd muffler or resonator.

What's my best option for the catback, quiet but minimal restriction. Perhaps I can't

have my cake and eat it? I'd rather not spend more than $1200 all up and would really like to keep my 'sleeper' style with twin tips on the end.

General rule of thumb, the better it flows the louder it will be.

For $1200, I would recomend getting the best flowing cat back you can and fitting an Apex ECV. you can quiet the exhaust down any time you like, or go to full noise if need be and you want the power.

For example, I am running an SR20 with manifold and full 3" exhaust all the way back, it has a resonator on the end, but thats it. Its a N1 type setup, so minimal bends (bends restrict flow even if they are mandrel bends).

It is bloody loud. For daily driving I shut the ECV and it is quite inconspicuous. I have had traffic cops (bike cops and car) sit behind my car at the lights and not bat an eyelid. Works very well, and is also great if you are leaving your house early or late at night, you dont have to piss off the neighbours.

Something to consdier.

As for where to buy. Autobarn now do genuine Japanese cat back systems from blitz at prices pretty damn close to JDM. Can go wrong with something like the Nur Spec, just throw on an ECV and you will be able to have your cake and eat it. :(

ecv = exhaust control valve?, is this like the stock control valve that some GTT's have? IE you can operate this is cabin to increase restriction or reduce noise?

Autobarn says $729 for Blitz Nur Spec S problem is these are apparently 96-105DB (has a removable baffle) while CES claim 86DB. Not sure what legal is?

Fujitsubo make really good quality stuff, my exhaust was 1100 for the catback, have the split front/dump and the $440 cat.

The exhaust is the Legalis R, 84dB at 4800 and sounds SWEET. Perfect for a sleeper like mine. If you want a bit more power, get the SUPER R.

By the way. If you car is auto...DONT, i mean DONT cheap out on an exhuast. I got a Xforce thing, its droney as hell and i HATE it...hence got this one

I'm just going to use one of SMB's 4" cats and Mufflers and make up the rest of the exhaust myself. Their website does make mention of a skyline catback comming soon though. My old man has their 4" turbo back job on his XR6, its pretty nice.

well, ive been stung with my "quiet" exhaust

its a blitz, and it sure is quiet, but its retarding power like crazy

im looking to get rid of it if anyone is interested in a quiet exhaust and doesnt care for extra power

I had jack to from turbo back on my last 2 lines... cost me $880 on the r33....

Very high quality of work and will always take my cars there.... Its 40 minutes away but i will always go back....

I used a 3" system with split front pipe through a high flow cat and 4" out let... Got tested by Police @ 89db.... So it sounds great and performs well....

    • I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.   
    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
