Thread: V8 Exhaust

I have an 81" RRC extractors, no middle box, standard rear box.
Sounds good to me, not overly loud IMO

Yesterday while towing the loaded car trailer up a hill north of gin gin there was a strange smell inside the D1. Pulled up at the top, had a look around and found the rear muffler last hanging by a thread, (of rust). So I kicked it off as it was hot and carried on and the smell had gone. The noise!! It was ok when coasting along on the flat at 96 but as soon as we came to the hills and the V8 started to work, it was like having an F18 under the bonnet. It goes in today to get a new mufffler fitted to the rear.

A few RRC's back I did a 4.6 with Haltech and a very good friend owned a exhaust shop on Regency rd here in SA.
I did him a contra deal with a few cartons of wine and he did a killer system for me.
The car was there for 2 weeks during the quiet period for him and he had his apprentice doing most of the work I guess.
It was a custom full stainless mandrel bend system, extractors the lot.
Mufflers were Remus which came off a Merc 500SL where the new owner found them too loud and they fitted perfectly.
I/he did a 2.5 inch system and it was a work of art.
The mufflers were actually beautifully tuned and sonded great.
The more revs the better it sounded, not really louder but just like music-to my ears anyhow.
Only problem with stainless is that when I went through water, they cracked twice at the extractor side where it bolts to the heads.

Not sure how much in $$$ it would have been but for a car that you have for keeps, it was great.
He made sure the back pipe went past the body too, otherwise it would/could have droned in his opinion.

Greag was his name and he did a lot of show cars and hot rods etc, I still have not found anyone as passionate about exhausts since, but let me say one thing-- Do not go too loud as the rover motors like to pull at low revs and loud exhausts sound like boats in Land rover guise.

Good luck

iv got the 95/96 v8i 3.9
i think mine runs the standard extractors down into a 2 1/4 lukey she sounds like it almost straight thro sounds neat

Hi,
I am doing alittle research and going by everyones comments i think ill go with a 2.5" system from the Y piece with 1 middle straight thru muffler (500mm long) and no rear resanator, but do i need to run a cat converter?
Cheers

Didn't like the answer you got in the other thread?

The answer is no, you do not need a cat on a D1.

I drive up the street and he stood there just shaking his head. It used to start off from the lights and people would look around looking for the ozzie muscle car and not finding one looking confused. Took it back cause I just cant pass myself off as 17. He said he couldnt believe how loud it was and had thought about it and reckoned it had to do with the engine being all alloy and putting out more noise than a steel one. He then changed the resonator and muffler to a more packed one but still good flow and the note was then very close to stock but better flow. I really like it now and its very liveable.

Be careful what you wish for cause there seems to me a big gap and no midway point between quiet and throaty to outright insane.

Hi mate I know this is an old post but just wondering who the bloke in Capalaba is we are looking to put a full system on our disco 2 and as mentioned in some of these posts some shops get weird when it's a Disco I think if it's not a Toyota or Nissan they don't want to know about it.

Thanks in advance.
