got quoted today for 2.5inch custom exhaust 850 installed at western mufflers. mild steel excluding extractors.

might get those coby ones from partsco.

anywho went to BEL and got quoted close to 1700 for the following

coby extractors $360 (get this myself)

bigger cat $440

HKS 409 (forget the name) exhaust 900 bucks

which should i go with?

will the custom setup give me the same performance gains as the HKS?

How big is the HKS 409?? what size piping

i tihnk its HKS 409 Hi power or something like that.

I reckon the custom exhaust unless your willing to put up twice that amount and go 1700.

but im not sure how good the hks hi power is.

thanks guys,

yeah its the hi-power silent one i think.

2.5"

the guy at BEL said they would need to cut off 6 inches though becuase it is an N/A

think i might go with the HKS one, bigger cat and get the extractors myself.

installation by myself probably.

$440 sounds a bit expensive for the cat - should be able to do better than that if you look around

Definitely fit it yourself, it's not hard if you have the right tools (basically just a good socket set and something to raise the car eg ramps/jack).

I have r33 GTS4 n/a. with standard exhaust. I really wanna just put a canon muffler.

1. Got quoted $280 for Canon muffler + Instalation (Muffler is some cheap brand I guess?) is this price is right?

2. How loud will it be when I put this muffler? does it depends on how big it is? like 3" tip and 4" tip?

****I had a cat back exhaust system before 3.5" pipe and 4.5" tim canon muffler, went back to standerd as it was loosing power due to lack of back pressure. But now I need little bit nice beat in the car, not too loud, thats why I wanna put a reasonable cannon muffler (my cat back exuast system is for sale by the way http://www.skylinesaustralia.com/forums/R3...8#entry3582368)

the price is right if you are happy with the product, it's impossible for anyone else to judge without having a look at it. best you go to whoever is supplying you with it and inspect for yourself.

2. How loud will it be when I put this muffler? does it depends on how big it is? like 3" tip and 4" tip?

this is your typical "how long is a piece of string?" question. loudness will depend on what other components you have, the quality and material used in those other components and the cannon. mild steel? stainless steel? titanium? etc.

tip size does have some affect on how loud it is. as a very general rule of thumb, the bigger the tip the louder.

okay,

theres a group buy $155 high flow xforce cat.

650 bucks for 2.5inch mild steel exhaust (custom)

might pick up second hand extractors.

cheers guys:)

saw a guy selling 2nd hand coby's for $300 in the for sale section.

keep us posted and when you get a video clip, post it in the sound thread

eug

Finally got it all done yesterday!

and im happy with the results

the car pulls alot better through the rev range and i get more out of each gear.

as i went from mild steel to stainless cat back the car has a much nicer growl. before it just sort of droned then droned some more.

the car is alot more responsive which makes driving it a lot more fun!

the extractors smoked some what but because i had the wrapping and high temp paint on them the coby paint didnt come off..

ill put a sound clip up when i can be bothered..

end of the story.. im happy :)

    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
