i'm getting a new exhaust and muffler and just wanted to know what ppl think is the best thing to get

i'm looking at getting a Manaflow race series muffler:

#14843

2.25" Inlet, 4" Diam. Tip

2.5" Internal Race Core

Single Wall, Staight Cut

4" Tip Length

14" Muffler Body Length

this any good for a N/A rb25?

and what is best for the exhaust, 2.5 inch or 2 an 1/4inch?? from extractors back

with a cat but no resonator, or should i resonator?

thanks every one!

resonator is a definite, i agree. Forgot to ask what the guy who replaced mine was going to use - so i ended up with a lukey race hot dog thingy :( .... murder at 110kmh (open road limit here in WA) 3" pipe probly doesn't help... SEVERE overkill on 2L N/A....:looney:

let us know how the change gos... might do the same thing :thumbdwn:

I got a 2.5" hks system with 2 resonators (hotdog resonator and a 2nd small muffler). It works well - not droney AT ALL. The end main muffler is a big barrel style muffler with 2.5" inlet and has a 4.5" tip - it is not straight through in design. I suggest you copy the design of this system (resonators etc) :D

2.5 is definately the biggest u should go, u should get more top end with the bigger diameter exhaust. 2 1/4 is good for low down power. The muffler itself is straight thru yeah ? i would go the 2.25" and a resonator to save ur hearing, but still have it loud :D

what brand of rear muffler do you gouys use/recomend? i have some Jaz - Jazma ? -can't rember exactly, something like that - i guess it's some cheap Jap brand, but it is straight through, like the resonator, on the extractors with a full 3" cat also...

just one major question, how would you fit an offset muffler in where ther is currently a straight through?

ie how does this;

??? given the way the pipe runs from the engine (tangled round diffs etc.) then fits into that little scallop out of the rear bar?

Jasma is just a regulatory body, like the EPA is Australia. It's not the brand of the muffler, but if the muffler is jasma approved it means it meets certain noise/pollution requirements and therefore is of reasonable quality. For example, my HKS system has a jasma badge on it.

i'm also thinking about a CAT back system - my budget aint that big - but i want something thats going to sound better and increase performance slightly...

i got quoted 290 fitted for a 'home made job', as the muffler place reckons you can't get one to just bolt on? That was for a 2.5" cat back (might only have been the rear muffler)

What kind of system do you guys recomend for 300-350 ish mark?

anything has to be better than stocko one!

PS: Sorry for the post hijack :D

can some of you guys tell me a few price u payed for your systems?

sorry dude, mine was already there... resonator cost me $120, extractors ~$350 i think ? can't remember exactly... the rest - gawd knows !

i have recently taken off my cat back exhaust as i was driving a bit of a road trip. I noticed quite a bit of power loss all through the range.

and Perhaps a week ago, i put it back on, and damn there is power again, noticable low and high in my rev range, but definately more at top end.

Mine is 2 3/4", and its drony in certain RPMs (mainly at 110 on motorway), most of the time, its sexy. Get a big resonator, big as possible imo.

You've probably already got it by now but go a 2 1/2 inch mandrel bent system. I've got a magna flow muffler, #14827, its a single wall angle cut 4 inch tip, but oval shape. I was told they had a slightly better tone and not as droney... not sure if its entirely true. They also fit more neatly under the car, however i was after the cannon style and they do look a bit better. I highly recommend magnaflow though, just ensure you put a decent resonator on as mine hardly does anything and it's fairly loud!

I think I'm going to finally get rid of the Genie Reverse Flow muffler off my car, its just tooo loud! Currently I have 2.5" Cat Back, with a resonator.

Anyone who has done their exhaust cat-back, what muffler and how much was it? An angled canon style would b good, but not really necessary.

I've used a MagnaFlow Street Serious muffler, the exhaust shop were retailing it for 374 but it may be cheaper elsewhere. Yeah the angled cannon style does look good. This one is an oval shape but exhaust shops do the angled bend if you just get a cannon style

Anyone recommend an exhaust shop in the Melbourne city area that fits magnaflow mufflers and will do it for a good price?

When I got the current exhaust/muffler fitted I asked them to put a flange so it can be unbolted, and its 2" up to just before it bends.

thanks!

Yeah quite a few places sell MagnaFlows as they're fairly reputable and well known. Depends where in Melbourne you are, i got mine done at Casey Exhaust which is in Berwick, they do a lot of work on high performance cars and have done heaps of skylines. The other place i know of that sell them is Dandy Exhausts but your best to just ring around as i'm sure many other places would stock them

I work in Parkville so yeah anywhere close to the city

What other options are there apart from magnaflow (seems a popular brand) for a muffler in the cannon style that will not be too loud, im sick of the drone of my current muffler.. but not too quiet as well (but under limit).

Cheers :)

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
