Exhaust, Mufflers, Etc

[zymotic]

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.

[zymotic]

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.

[Spook's_Skyline]

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

[zymotic]

what model Blitz? just catback?

[Spook's_Skyline]

yer catback

ive got a hiflo cat and dump pipe from batmbl

[Col-GTSX]

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....

[zymotic]

Might get BATMBLs split + cat and Jack Beedhams's cat back. Have u got a resonator on your's Col? or maybe middle muffler? Also what kind of end muffler - not a cannon? I could live with 89DB i reakon.

[Col-GTSX]

yes its a cannon and no i dont have a mid muffler....

Its a straight thro system.... Just a cat and rear muffler...
