TD100 Mandrel bent exhausts...What's the diference????

I'd normally agree John but from what I've been able to find out there isn't much difference between one 3" mandrel bent system and another except the muffler.... and that seems to come down to whatever 'free flow' type the shop stocks at the time....

As long as it's 3" with a free flowing muffler, I don't think I would be able feel any difference no matter who made it....

Cheers

"As long as it's 3" with a free flowing muffler, I don't think I would be able feel any difference no matter who made it.... " I agree with that point Andrew. I do think the Taipan system is marginally less restrictive though, much along the line of the Vortex designed system. It can be noisier than your noisy tyres though. On the Nissans the Beaudesert system is quiet.

I am more concerned about the build quality and where stresses are built in causing fractures further down the track. People have made a point about the dump pipe of one of the manufacturers, but they both look well manufactured to me.

To any Nissan owner, the difference between the OE dump pipe and the upgrade is palpable. Not so much from the OE Toyota to the upgrade. The Nissan OE pipe is hugely restrictive.

I did it...here's the run down for me...

It's a Mercury system, mandrel bent, bolts straight in.
Came with the dump pipe, (twice the size of the standard one in length) opens to 3.5 inch but goes back to 3" conecting to the exhaust. Then 3" all the way.
One muffler and small resonator at the rear but all straight through.
One very good thing is the dump pipe comes with the fittings for the heat shield and a pre-drilled outlet for a pyromometer if you want one fitted.

Over-all, very happy with the quality and fit. It mounted straight into the original position, no mods required, 2 hr job.

PERFORMANCE
Very quiet....barely any difference to standard unless standing at the rear where you get a slight 'rumble'...but nice rumble.

Much more responsive off the mark. I have spent yesterday driving around Perth and the city area. Noticeable difference, lighter under foot, less excelerater to get going. Very noticeable in heavy traffic under light acceleration. More pleasureable to drive.

I also notice a change when cornering. slow corners that resulted in acceleration use to mean a kick down back to 1st then off again. Now it seems happy to pull away in second. Don't notice any difference in other gears though.

Highway run today back home (224km's from refuel at Armadale) perfect weather...nothing really different at cruising speed noticed. Didn't do a proper fuel test but for 224k's covered, my main tank guage is sitting just under the 1/4 mark.

Only other thing I notice is that an existing 'vibration' I have a certain RPM now seems worse...don't like that...but will start investigating the cause more closely and seewhat I can find. Feels like driveshaft/uni joint type thing but I've checked all that and it seems fine. Bugger of a thing these annoying vibrations!

Just to clarify the fuel used bit...I mean the needle is sitting just under the 1/4 used position...so I have almost 3/4 left in the tank...you know what I mean!

Very good sounds exactly like mine pyro inlet and all.

Get it dynod and see if it beats 165HP.

My fuel consumption hasnt changed

Car just goes like you say and when you boot it hard no black smoke.

now in Bunbury

I had a dyno done about a year ago...just after I got the Dtronic. The report reads...

Maxima (corr.) 167kw (227Hp)/ 3431 Rpm and 518Nm/ 2722 Rpm.

The guys at the shop said this was good.... It's a bit Japanese to me!

I guess with the new exhaust, these figures should slightly improve.

These figures are quite a bit different to yours..I don't know why that is.

I have the Dyno report in my hand, can show you if we cross paths..

Yep I reckon I know what they have done..

The Corr stands for corrected.

Manufacturers give power readings at the flywheel which is best cos it doesnt have the tranny etc dragging it down.

So they have adjusted the readings to give an approx equiv reading.

The max Hp at 3400 is pretty up there. I never rev it that hard.

Max torque is good at 2700 but I cruise at 2400 usually Uses less fuel at that.

Mine is an at the wheels reading and unfortunately the dyno was their old one which was in HP.
They have a new one now but Im not there.

Mine gave an original reading of 145hp at the wheels and following the chip same as yours and the exhaust went to 165.2 at the wheels.

Which they reckon was at the higher end of the ones they had done.

Give you a race but I have about a full load in the back.

Cheers
