Quieter Oval Exhaust

[rondofj]

Got a quote from Castle Hill Exhaust in Sydney for supplying and fitting Xforce MP02 muffler onto my R34GTT to replace my current monster canon which is too loud for me. I was quoted $350 and have heard many good things about them.

There will be some pipework from the diff because my canon is angled and the new bit of piping will be 3" and not 3.5" like my existing (from diff back only, the rest is 3"). And the exhaust will be straight of course.

Has anyone used this muffler and what are their views? Quietness/drone etc; Or should I go the twin tip version MP01?

What do you people say about the price, anywhere else cheaper for a reasonable job?

have looked at Lukey mufflers, they seem to only have the middle mufflers, not the rear muffler like MP01?

cheers

I have an oval middle muffler (3" hi flow) and a 3" cat as well but no resonator.....Do I need this to reduce drone or will the oval rear muffler be enough?

With a 3 inch pipe you will definately need a resonator to quieten it to a legal level, if not two!! As well as a decent muffler...........

i have the oval one and its pretty quiet and looks good

they seem like a very quality muffler

hope this helps

oh and this is on r33 with 3 "catback hi flow metal cat and split dump pipe

Two resonators? Better off putting in another muffler.

If you dont have the space/clearance under the car then what i suggested is another option.........

Skylines have room for two very decent sized mufflers without a drama in the world.

You can get 3" exhausts down under 84-86dB (90 is legal). No need to waste time with resonators.

I had the twin outlet Xforce on the stagea with a reasonable mid muffler. I am a bit of a fan of the sound of that combo. (3" exhaust)

Mrs Wolv wanted the car dead quiet so the rear muffler was replaced with a monster custom made straight through. From memory it is 18"x12"x8" the largest thing we could fit in.

It is very very quiet now.

Thanks guys, my mind is made up - Xforce MP02-single tip is going in soon, middle muffler and everything else stays as is except the 3.5" pipe after the diff (dunno why the previous owner put that on when everything else is 3"), this pipe will now become 3", will keep you all posted on the results next week..

Also lookin for some cheap used Jap wheels only, drift/deep dish/aggressive style with low offset - theres Otomoto in North Parramatta, they got cool stuff but currently not what I want, does anyone know of other places in Sydney????
