My new sports cats

[maverick]

Well today I have been to Josh's at berkshire garage to have my sport cats fitted . I had the flanges lazer cut (cheers Spartacus ) and purchase some magnaflo cats and landa bosses .I fabricated the flange ends with oval to round made the brackets and temp probe bosses . Than josh did all the pipe ,work really pleased with the results . Looks like I just caught the original cars in time as there look like there are starting brake up .

Looks a tidy job there Maverick. If you dont mind me asking what sort of cost was the conversion from the oem cats. Have you had a change in exhaust sound as a result ?

 

[Zep]

The looks brilliant, are the pipes under the steering rack fully round or squashed?

The guy Josh does all my work and he is a perfectionist. Call him up , you will not be disappointed. Mavs car sounds really good now.

Theres a little more bass and loudness just right not to effensive ,and no drown at all .

Total cost is around £550

Clearance problem over speed bumps?
The reason why the OEM is squashed, and the larini offering is twin smaller pipes per side.

These sit higher than the OEM squashed abominations so no clearance issues at all.

How can they sit higher? The reason they are squashed is because of the steering rack. Larini use two smaller diameter pipes to get the right gas flow with decent ground clearance. Bigger diameter pipe means reduced ground clearance.

Top job Mav, good to see, did you need extended rear sensors?

It's down to the pipe work on the originals. There certainly is no difference between OEM and I'm pretty sure when they were measured they sat snugger to the Subframe/steering rack than the OEM pipes, I'm sure Mav will correct me if I am wrong.

No need to because of the way there are original routed there's plenty of cable length , difficult to explain really but we just reverse the bracket that holds the plug around a rethread the cable , to be fair this was my main concern but turned out to be really easy to sort .

There may sit a little lower but not by much and the position is right between the wheels so as long as you have one wheel on the speed hump there will be no problem which is good practice as straddling a speed hump can damage your wheels or your tyres more to the point just ask my mate with his BMW who has just had to replace he's rear tyres both inside edges down to the cords with loads of tread on the rest . Been over several today and no issues , I really didn't want the squashed parts and the twin pipe just looks to fussy .

That doesn't sound like speed hump avoidance, that sounds like a rear camber issue. Tell your mate to get it checked.

I have to agree. I've never quite understood the logic behind speed humps damaging tyres / wheels unless you hit them *hard*

That's what I told him !
It was like the side wall not the actual tread part if ya get my drift ,apparently quite common on those elastic band tyre but thats what the tyre fitted said anyway

The rear tyre wear issue happened on my first alfa 156. Tracked down to worn bushes in the back suspension. No knocking or warning of any kind. First i knew was when walked up a hill towards the rear of the car and could see the inner edges were shot on the rear tyres.

I'll tell him to go and get it checked out I must admit when i saw the tyres my first thoughts where camber issue

Well done on the cats, good work

 

[Contigo]

Have to admit, this option seems the best way of getting around the cat issue some of you have faced or potentially face going forward. Maybe time to fabricate the pipes and flanges etc...
