Im considering getting a Herrod Stealth installed on my F6 Tornado before I pick it up. So I called Herrod today and spoke to a guy there (not Rob) who basically told me on the Tornado I would be much better off getting a cat-back exhaust system fitted BEFORE the edit as the stock exhaust system is very restrictive.

He recommended I wouldn't get much extra power with the stealth without the exhaust mod first, probably 20kw.

Now this goes against everything I've been reading about. Especially from Herrods as from memory they almost guarantee an extra 50kw off the shelf.

Tell me this guy was dreaming?

I'm aware a custom tune would definitely be better than an off-the shelf stealth. So that will come later.

From my experience I would strongly recommend you do the edit first. I own a Typhoon and living in Perth, was able to get Simon from Xtreme to work his magic on her. No mechanical changes what so ever and he was able to find an extra "50rwkw +". She now runs 252 rwkw on all standard mechanicals. Worth every cent!

Stick to WA mate..... Simon has done probably more Typhoons than any one in aus and we know he has done probably the first 2 Tornado's in Aus with a lot more than 20RWKW's so why would you go east for a tune?
Its all here in your own back yard!!!!
Look at Peters (Aussie_Geo) for example thats 44rwkws up on my stock dyno STD.

Mate no worries about that. If anyone is going to be tuning it it will be Simon I can guarantee that!

Because its a lease vehicle if you recall, I have to sort out what mods I want BEFORE I take delivery of the vehicle. So I have to think about these things now. Im going with Herrod because McInerney Ford (their sole WA distributor) say it does not affect new car warranty. They'll be fitting the stealth, then I'll get Simon to tune it.

Yeah thats what I thought Aussie_Geo cheers.
I dont know what this guy from Herrods was talking about. Perhaps looking for more revenue?

Mate, from the cat back is twin 2 1/2".. the restrictive part is the cat.. Ask him where he gets his information from, based on what results.. Also ask him what he reccomends as a replacement exhaust ( just to humour him ).. twin 2 1/2 is equal to a 3 1/2" single, so he'd better be backing a 4" drain pipe in his package, if he wants to improve' your exhaust flow... Remembering by the time it gets back there, it's cooled off and 2 x 2 1/2 is plenty for just an edit/injector combo..

Maybe he'll tell you they have 'hi-flow' mufflers or something..

Dump pipe and cat maybe a worthwhile replacement option, if they do them, but by the looks of their site they don't.

BTW, their cat back exhaust on average gives an 8rwkw gain over stock..

Tell them what YOU want, not the other way round.

I just called him to ask how much their 'off the shelf' Stealth tunes will give me, and if they have an F6 tune available too. Then he went into the 'exhaust first' spiel.

Of course he recommended their own $700 cat-back system.

I had none and still dont have any plans to modify my exhaust as Ive heard plenty that the stock system is fine up until around 300rwkw.

Sounds like they only want to sell the addons. Not knocking Rob, but it is pretty sad that they will try to push their other products on you when you dont need them or want them.

Personally I would stick with the stock system and maybe just add in some higher flowing cats. I know that Simon was working on a comparison for them.

Who did you speak to there?? pm me if you like.

I think they are trying to extend their bank account, the Typhoon system is capable of flowing at least 350 fwkw before it becomes restrictive, then all you have to do is put in a 3'' hi flow cat and it will free up. n entire new system will only give you a different note. The restriction is in ther cat, not the exhaust. Save your money for other things, like bigger injectors and an edit.
