Not a bad echaust at all. Fitted it to a mate's S2, and considering it's a 3inch bore, it's pretty damn quiet. Not intrusive on idle or when cruisng, just gets a litte boomy on boost around 4k. Thought it would be deafening, but quite civilised

 

you should try the 4" exhaust!

Booming!!

 

he likes it then.



Dave.

 

Love the one on the new RS. makes the right sound at the right times.
Not wishing to start a war but I rate it far higher than magnex. Better build too.

 

hell yea Dave!

But, we need that bracket as it's a bit shonky at the mo!

Matt - 3 inch is the biggest there is!

 

I think Rick is referring the 3" bore as opposed to 2.5". There is no such thing as a 4" bore exhaust for RST's.

I have the 3" bore, 4" tailpipe and was also very surprised by the quietness of it. It's not quite so quiet now, but that was self-inflicted.

 

we talking bore or tailpipe?

ive not had a 3" tailpipe on my car, but from experience mongoose are the muts!

 

bore mate, bore..... The 1.2 corsa down the road has a 4inch tailpipe!

 

It's the mongoose 3" bore system, it has a 4" tailpipe. I had one on my RST. Top quality exhaust! Waaaaaaaaaaaaaaaaaay better than magnex.

 

talking 3" bore all the way to the back box std RST exhaust is 2.25" and a normal mongoose/scorpion etc are 2.5" bore reguardless of the backbox

 

sorry - am very tired after 10 hrs work today! just seen it in the first post!

& yeh mongoose over magnex anyday!

 

I'd say scorpion for an ERST

Fits nice, sounds the tits and top quality.

 

HA

Rick- it does out side mate I have one of them jobbies

Jake

 

Oh the pain

 

Possibly the worse exhaust you could fit

 

I liked mine on my old one, could here it ticking over on the driveway from my bedroom

 

same here mate - nowt special about that!!

 

Shame there MORE restrictive than a std RST exhaust

 

pmsl at scorpions

 

still think my magnex was shaarmone motherfuka

 

Rick, are you at Castle Combe on Saturday.?



Dave.

 

Aaaaah, Magnex. Now all is apparent. That's obviously where all the missing Horsepower was.



PMSL @ Scorpion. 2.5" Bore and 1.5" through the backbox!!

 

I had a bit spare if you needed to borrow some

 

Oh yes please. Save me struggling in vain.

 

Dave - Rick say's he's working Sat

I was impressed with the price of them new when I priced one up for someone recently too

 

The 3" bore exhaust come with silenced back boxes where as the 2.5" dont

 

how did you find fitting it, i did one recently and it was a bitch to fit and none of the clamps would hold it up tight enough which allowed it to sag alot so had to get it held up and welded in position

nice exhaust just a shit fit i thought

 

I like the way most people think they have a 3in bore Mongoose, not very easy to get hold of and are a pain to fit (so I hear)

3in bore Mongoose exhausts are meant for BIG bhp cars, I mean BIG bhp, not run of the mill 230bhp (2.5in bore easily matches spec of car then)

Ah well, I know Christian's is WAY quieter than it ever used to be, but as you say when on boost - can certainly hear it coming LOL

 

Its important to note that the larger the exhaust, the lower the back pressure. On a car that doesn't require the flow level that the 3" exhaust will provide, it will probably feel slower and less responsive.

On a 250+bhp RST, I think the benefits are worthwhile though.

 

Hardeep if u have that issue just use 2 u clamps to hold it.

I had that issue and 2 u clamps stopped it
