Subaru exhaust.. trial fit

Post by matt brighton »

Hi

Prices of a bespoke proper system are staggering .

I initially fitted a gsxr 1100 can with lambada to "get me going" - and I'm pleased with how it looks and sounds - well...maybe a bit on the noisy side under load -

I'm now going to see how a ford focus ST exhaust works -

It'll have the "requisite" (for me anyway) twin pipes at the rear - I will let you know how it fits/sounds

it may be an affordable alternative

Yeah let us know how it goes Matt. The exhaust I knocked up in 1.5 inch pipe with standard silencer is pretty restrictive although it sounds ok.

Will do,

I have alot on at the moment, so it may be a while till i get around to fitting but i will post how I get on -

The twin pipes look good.... but its just seeing how the box can fit .... I will try to bracket it off the engine block rather then hang it off the body so theres no stress of flex

Sorry Matt, not had any daylight access to it since, I'll try get one tomorrow. Its 2 brackets hanging down either side of the crank pulley, using threaded holes that are in the block already, for a power steering pump and aircon pump (neither of which I have). They hold a cradle to take the weight of the silencer.

Thanks

Photo would be good - I might use the redundant mounting holes for the diesel cradle ... be useful to see yours tho as I think engine mounted reduces stress

I picked up the 2017 RS Focus S Steel exhaust yesterday , - the chrome twin exit pipes are massive !!!!

Fits between the engine and rear valence well

Its also got an actuator valve effectively a butterfly that shuts off flow through one of the pipes - opens on a servo in "sport/track" mode

I might rig up a cable as i know when I want it to be loud/quiet

Have ordered a reducer pipe as needs to go from RS Focus 70mm bore :shock: to the subaru 55mm manifold pipe bore.

Bought a DK box - yet to be picked up and fitted but hopefully more relaxed at 60/70ish ... it was a bit revvy at over 90mph yesterday .... about 5000 rpm if I recall ,

Don't plan to be in that territory often... or for sustained periods but nice to know.

Blimey cool. I've seen One of those close/open valves on an exhaust, I had no idea about them. But 90mph.. wew! Bet that was hairy. Road and wind noise in these things doesn't make for a relaxing ride. I have an 8E gearbox. Can't remember where That stands in the ranks but it's good to remember revs aren't necessarily a bad thing and don't always equate to fuel consumption. Be nice to lower the noise at motorway speeds though I'd think. My mind imagines crank shafts and pistons spinning wildly at 5/6k and I always back off. Red line cutoff is 8 I think- never got close!

8E is according to RJES website colour coded table at the taller - but not quite tallest bracket

http://rjes.com/html/gearbox_types.html" onclick="window.open(this.href);return false;


By tallest I mean will be lower revving at motorway speeds

My DK ....yet to be picked up and fitted, is I think ....in the tallest geared bracket but not featured in the chart ....

How did the rs exhaust sound like, asking as I have one siting in my shed. And does the flap make much difference when it's closed
