I'm looking into getting a milltek for my 2003 blob sti uk and have noticed they do 2 sizes 2.75" and 3" bore , would there be a major difference in sound and performance ??

 

Assuming the car isn't highly tuned, the 2.75" covers it performance wise. I'd say these systems aren't "LOUD", in a good way and are very well finished.
We supply Jetex, Cobra and Milltek, with a discount.

I had a Milltek full de-cat 3" system on my classic. Sounded good and wasn't all that loud (I later changed it to a louder system). I wouldn't say the quality was all that great though considering what they cost.

 

I'd certainly agree with Matty's first comment.

A fellow SN member was interested in the low volume of mine.
I don't know exactly what the system cost but I know that:

a) Litchfield were impressed enough to include it as part of their 'upgrade'; and
b) it's been on the car for 8 years and has no problems whatsoever.

 

Don't bother with off the shelf systems, get a custom one made at Infinity-Exhausts. They will make it exactly how you want it in stainless with lifetime warranty for half the price and much better quality

 

I want a milltek as the are quiet , just didn't know how much difference the 2.75" to the 3" would be power wise , aiming to go 400-450bhp

 

Infinity will dsign you one that quiet for around £350

 

Full system or cat back ?

 

£350 for 3" Centre and rear sections, so everything but downpipe.

 

Thats a £100 cheaper than Miltek and better quality materials and better flowing system. A decat downpipe will be around the £180 area which again is £70 cheaper than Miltek. Infinity number is 01454 273 123

 

I have had six exhaust systems done by Infinity, and for quality, sound and performance i would never go anywhere else. Plus there customer services and after sales are second to none.

 

I can get the 2.75" milltek system for £330 which I think is cheap

 

£320 delivered from us..

 

How much for the 3" ?

 

It's £468.84 delivered.

 

Alan I have the Powerstation/Litchfield 3' system on mine with the spots cat centre, how restrictive do you think the cat is and how much for a decat centre to fit my system in 3'?

 

Love my 2.75 cat back miltek with the 'special' back box

 

What different back boxes do milltek do ? I am aiming for around 400-450 Bhp which exhaust out of the two will be best suited ?

 

I'd put the 3" on at the power level you are aiming at, I put the miltek 3" with sports cat on 6years ago and it's served me well from 300hp at the time all the way up to 440hp.

I've a 3" with sports cat on mine and it's pretty noisy but in a good way. Perfectly fine but it can get a bit annoying on long trips. Excellent build quality too by the look of it.

 

Sports cat centre? I thought the Milltek systems Litchfield's supply just used a sport cat downpipe with open centre pipe?

 

The 2.75" isn't restrictive at those flow levels.

 

Got miltek on mine lovely system not to loud either

 

I have a MillTek 3" system with sports cat on my JDM Legacy, 335 bhp... I love the sound
