Muffler options for TD27T 2.5"

Postby fullthrottle » Sun Aug 03, 2014 8:21 pm

Hi All

I'm in the process of rebuilding my exhaust for the TD27T. Built a custom dump pipe from the turbo into a 2.5" exhaust.

I just want to take the harshness out of the sound and keep the WOF man happy, but also have no flow restrictions.

A few options I've found so far...

Has anyone had any experience with these and/or can recommend a good muffler option?

I have one of these personally, smooths out the roughness but still gives you body & flow :twisted:

chuck anything thats straight through on it. the turbo takes most of the noise out anyway.
don't bother with a flow master, their design doesn't work with turbo engine (according to flowmaster site, they have straight through mufflers for turbo engines).

X2 for the Coby (or similar) I personally think the Flow master is a lot quieter, probably half as loud as a straight pipe.

Edit:
This is what the $80something Coby sounds like

I just had a 3" incl dump put on my surf 1kz-te and used the scavenging type (1st link) resonator. Good sound and excellent flow. No noise issues at wof and good results on dyno too ;-)

Yeah I didnt really consider that about the flowmaster, seems to be fine for my 100hp forklift diesel doing 11psi anyway.

Its definately a lot quieter and not obnoxious sounding, but has a good bark when you 'get on' the fuel pedal.

I think the snorkel/intercooler/dump size/length of exhaust system makes a big difference to the overall sound/character of the thing too.

Every diesel likes to take a good dump

Cheers everyone for the replies. I've got 5.5m of 2.5" pipe to play with, so I'll do a straight pipe first and then bung a muffler in after if the sound is a bit much.

By the way, if you ever need a flange cut for the garrett turbo (kidney shaped) exhaust outlet, then these guys now have the pattern on file and can cut you one in about 5mins.

I just run the 457mm one of these http://www.chase.co.nz/category/105/Louvred-Centre-Tube on mine now, tho it is a little tractor sounding at lower rpm.
If ya want something a little quieter, I ran one of these http://www.chase.co.nz/part/582/0/RD41266 for ages, seem to handle the diesel vibrations no worries, and did sound a lot better than the hot dog does.

screw the mufflers, TD27-t's are quite enough(just) for a WOF with striaght pipe.

it's the hilux engines they WOF guys complain about.

Surprisingly true.
I did go with the straight through 2.5inch in the end. Sounds fine to me and Mr WOF.
I also had to rebuild the little 1.4 Astra exhaust and those things are bloody obnoxious in comparison.
