Some pics of my new exhaust...

[merlin's S4]

I've got some camera phone pictures of the new exhaust on my S4, not had chance to take any decent pictures yet.

It took 13hours to build, and I stood watching in the freezing workshop for all of that, apart from when I was off making coffee for everyone! I'm very pleased with it, although the V-band is blowing a bit but that should be a simple enough fix.

316 grade Stainless steel 3" turbo back with 100cel race cat, twin Magnaflow boxes and twin 3" tailpipes. The cat and flexi are welded into the downpipe and the rest of the system attaches with a V-band clamp.

Nice one, thats more or less what i've got on mine,altho just got a single box at the back. The V-bands should not be leaking already tho, i had this - having drove it all the way back from Lincoln way, all 3 were blowing by the time i got home.

All 3 were faulty and replaced no questions,i'd suggest the same if they can't be tweaked. Best of luck, try and get a sound clip up.

That doesn't sound too promising! I'm glad I didn't have the other V-band fitted at the back now. I was offered the choice. Hopefully this one can be "tweaked" as you say. I don't particularly fancy another 600mile round trip just yet.

Put it this way, when i got back and it was blowing i drove straight to a local Exhaust place (our local Hi-Q is a shi**y Powerflow dealer), they got it on the ramp and said they couldnt do anything with it and they'r unfamiliar with those V-bands. They were creaming it over the quality and welds of the exhaust tho.

Car had to go back up to Lincoln for something else so all 3 were replaced. dodgy batch apparantly, hope yours isnt one of them.

The V bands leaked on mine too. If you split them and put a smear of exhaust sealant on them they seal up a treat. It's a bit of a pain and it kind of defeats the aim of their convenience, but it does work.
Oh, the sealant I used ( Halfords own ) worked best if you let it dry or bake it with a hot air paint stripper before running the engine!
Glad you got it sorted in the end Tris, long wait eh?!

PS: very preatty!

Looks really tidy!!

[Acidburn]

Was this another ojz engineering exhaust system?

did you go direct to them?

looks nice and the welds/size look good.

Small boxes, how does it sound? What size is the pipe?

I wouldn't say they were that small, tis a big car. Pipework is 3" from the turbo back. Sounds bloomin lovely!! Fairly loud but tolerable.

Don't think it is as OJZ use grade 304 steel on 90% of their stuff and Merlin states it's 316 unless it was by request.

316 isn't better than 304 in an exhaust application

But it's not worse either!!

304 and 316 are very similar, although technically 316 (also know as marine grade SS) does have a slightly greater resistance to certain types of corrosion.

No it wasn't OJZ.
