Hello again,

Firstly I would like to wish you all a Merry Christmas and a fantastic 2010.

Within the next weeek or two, I am actually considering a cat-back system for my ST3, but keep delaying myself as Im not sure if I do or not? I am after a nice sounding exhaust on idle, and normal driving, but DO NOT want any drone noise when doing Motorway speeds. I just do not want to pay £300.00 plus, for me to regret it when driving down the motorway.

If I do actually purchase a cat-back system, the manafacturer will be Mongoose. There are only two tail-pipe choices I would be interested in and they are;

a) 4" Rolled-Out
b) 4" Rolled-In

Will either of the above tail-pipe size fit within the standard measurements of the rear bumper without modification? In your own opinion, what tail-pipe design is the most popular? And, would any member, who runs the above system, be able to confirm the noise during motorway speeds.

The reason I am asking is my old Escort RS Turbo ran a 4" Magnex full system and was great but my mate had a 4" rolled out Mongoose on his Escort RS Turbo and we could not stand the drone above 70mph on the motorway.

Any advice will be very helpful and apreciated.

Thanks again!

Wesley Jordan

Ooooh, oooh, oooh.....I've always wanted to say this!!


Ahem.....

"I run a full Mongoose turbo-back system...."



And there is no noticeable drone at any speed (including motorway driving).

I have the 4" rolled in tailpipes with an unmodified rear bumper, and I think it looks just fine.



I am delighted with my system, and I am absolutely positive you would be too.

Clearly there are alternatives to Mongoose on the market, but if you have made your mind up, then I really don't think you will be disappointed.

Do it!!

Those tail-pipes look fantastic. Judging by what you stated, I will certainly be looking towards the Mongoose system. Silly question, you don't lose the noise of the engine from fitting a perfomance exhaust do you?

You don't "lose" it - but it IS different.

I like it.

It's hard to explain, and in any event I am probably not best placed to make a comment as my system is a full exhaust (i.e. downpipe and sports cat).

Your best best is to go out in another car that just has the catback fitted and see what you think.

I know "Donna" has the Mongoose catback fitted (but standard cat and downpipe) - perhaps drop her a PM and point her at this thread?

Your bumper won't need any modifications to fit any of the Mongoose tailpipes, they're all designed to fit the standard bumper exhaust cutouts.

Generally the 4 inch rolled in are the most popular, but it's up to you which ones you like best. There's tone of members with different exhaust tailpipe variations so take a hunt of the forum to see what they look like (if you're not already sold by seeing photos of Rambo's rear end
)

I can't see you having any problem with drone on motorways etc running the cat-back on it's own. The standard cat will still keep things quiet - I ran my car briefly with Magnex cat-back, standard cat and Magnex downpipe and drone wasn't an issue. From my experience with magnex/mongoose etc drone on motorways will come from running a decat, if you run cat back with or without a big downpipe you'll be fine as long as you keep some form of cat in the system.

Might have been different back in the RS turbo days you've experiance of but for the ST the Magnex and mongoose systems are virtually identical apart from some minor details so i'm on pretty safe ground using the Magnex as a comparison

So by the sound of things, it's the Cat that prevents any drone noise, as a few people have stated that their exhaust sounds great and not too noisy. My RS turbo never had a Cat fitted, so this might explain as to why it droned terribly.

I think I will now be getting a Cat-back system.

Does anyone have a picture of their ST with a 4" Rolled-Out til-pipe?

Cheers for all of your replies and advise.

Check this thread out. I had it saved on my favourites from when I was deciding on which one...

http://www.focusstoc.com/forums/Tail-Pipes...=mongoose+slash

I wanted the 4.5" slash but there was a mix up and I ended up with 4" rolled out. they don't look as big and daft as they look in the pictures on this thread though. I will try and get some pictures tomorrow for you mate.

They kind of remind me of the old school style of a Sapphire Cosworth (but two pipes instead of one)

I've made up my mind that I like them now after being unsure at the beginning. They look better once they're sooted up inside and you just clean the rim (ooo - er
)

I have done it, I have finally purchased a Mongoose Cat-back system with a 4" Rolled-In tail-pipe (as they did not have the Rolled-Out in stock).

Does anyone know where in Dagenham, I can get this exhaust fitted as I do not fancy doing this on Axle Stands?

I have been quoted £110.00 by Elite in Rainham which is very steep. One of their team mentioned that I might have to drop the rear axle to fit the exhaust? How true is this statement?

I think i paid £120 at AmD Essex near lakeside, they had to cut the old exhaust off as what most people do to prevent dropping the rear axle, but because the new exhaust i had was in sections ie. cat back, sports cat, downpipe, they were able to fit that without dropping the axle.
To be honest i doubt you will find cheaper than £110 that you got quoted!

hope this helps

I got quoted £340 supplied and fitted at Profile so that's about 50-60 quid fitting on top of the exhaust price

I can get my Mongoose exhaust by my mates dad for around £60 which I think is a good price. My Mongoose system has arrived in sections, cat-back pipe, back box and two tail pipes so hopefully this can be fitted easily.

A lot of people say that the original exhaust will need cutting off, but does that mean then the original exhaust is useless and cannot be used again? Is it possible to refit the old exhaust after cutting as when I PX my car back to Fords in two-years plus, I have plans on refitting the original exhaust etc... Can I do this without buying a new Ford exhaust.

You can re-use the standard exhaust no problem


Just make sure you don't cut the original pipe on a bend - leave yourself maybe 2 inches or straight section either side of where you cut, then all you need is a joining sleeve and 2 clamps and you can rejoin it easily enough. There are part numbers listed here somewhere to get the bits off Ford or you can get a sleeve kit from places like Wolf, they don't cost much.

Thanks for this reply. I was hoping for this answer, and has now put my mind at ease. Once the exhaust is fitted, I am hoping to get some photos done etc....

Cheers

Theres an exhaust place (cant remember the name) five minutes away from you in Kemp road, just off valence avenue. I used them for both my ST's and they only charged me £70 to fit a full turbo back system, and £70 to refit and weld the original when I put the car back to standard

So for a cat-back, I would expect to pay £40-£50
