sick of my exhaust.

[aziraphale]

does anyone know a GOOD custom exhaust place round the york area? im so sick of taking my 156 back to the garage for exhaust work, i just want it stripped, re-welded, re-flanged, whatever. it will not stop blowing, and im not taking it back to that particular garage.

i know a very good exhaust place, but they wont touch a custom.

flange at front of sports cat, welds on sports cat pipe, flange at rear of sports cat(all custom) and the backbox to centre connection are the problems. ive clamped, re-clamped, gun gummed and re-gummed, and it still blows. sounds fine for the few seconds i can get the gum to hold, but next time i start it it blows it out.

failing a custom place, anyone handy at welding and have some ramps?

If you fancy a trek up to Darlington the local Powerflow franchise are good..

[aziraphale]

think i may have to

[marko]

there is also a place in boldon just past sunderland that would be able to sort you out mate but the darlo place is a lot closer for you

Now see having owned a Saxo and being on a online forum I used to hear alot about custom exhausts and heard alot of mixed reviews about powerflow fitters.

But if one comes recondmended then Id go for that. Your best bet is to have the complete system looked at and see what needs doing.

aziraphale - i got my powerflow done in morecambe but if you have a look on powerflows website im sure it says there is one in wetherby which is not too far away from us

[156_TSpark_Boy]

The best advice i can give is the same I used to give to Saxo owners is:

Go in talk to the fitters, maybe even to the point of asking to have the car put on the ramp and have the system looked at.
Make sure your happy with what you both are agreeing on then make a appointment.

I think the more interested and keen you come across as the better, but thats just me

[aziraphale]

cheers fellas, sorry for not replying, yet again no reply notifications...

i may have to go to the wetherby powerflow dealer, although im going to wait until my new manifold arrives, im pretty sure the downpipe is blowing too, so have invested in a supersprint manifold/downpipe..

I didnt know they dont a manifold for the 156?

Got a link so I can have a look at the product.

[jug]

powerflow franchises are always good, its almost suspicious.

[aziraphale]

156 tspark boy, the link is supersprint manifold

currency converter shows that as being £459.96.

mine cost £200.

What a bargain! Ebay?

[aziraphale]

yep, and brand new, clearance item. bit of an issue though, wrong mating flange at the cat end. manifold has a 3-bolt flange, mine a 2-bolt..

[Pud237]

It can be changed though, thats not a prob. Or just whip the cat off altogether..

[156_TSpark_Boy]

Not sure I'd bother with changing the manifold myself as the 156 has a 4-2-1 anyway, for what it costs to buy and replace the gains cant be that great - can it?

Anyone know what kinda pony power increase we are looking at with a Supersprint 4-2-1 over Alfa 4-2-1

I'd say probably aroud 1-2Bhp at best, the greatest gain is removing the cat from the system but then every time its mot season your back under the car again.

[156_TSpark_Boy]

Agree, Id save the money and put it else where, I dont think I could be bothered mucking with changing the cat twice a year:

Once to put it back on for the MoT
Twice to remove to go back to decated

A decent cat back system either single box or twin box, an investment in the induction area whether it be aftermarket or modifed GTA and then leave it that imo

[aziraphale]

the supersprint manifold doesnt replace the cat....its just a combined manifold and downpipe. the lambda is in roughly the same place, the separate section you may see is a bolt-in flexi section.

[aziraphale]

DP, but i bought that because i need to replace my downpipe, and cheaper pattern units are crap, at best. welds on the inside of the pipe reducing the diameter? think i will pass.

[Pud237]

The Supersprint manifolds are tuned length as well I believe, whereas the normal manifold, although its a 4-2-1, I don't think it is.

Any idea how much a powerflow system (cat back I suppose) would cost for a 1.9 JTDM GT?

What do you want from your exhaust system? Looks, sound, performance?

[Eddie Bermuda]

Just a standard, stainless steel replacement.

I'd wait til you need one, your exhaust shouldn't need replacing yet should it?

[aziraphale]

ok, im dragging this one back up. im back to square one. the exhaust has not so much a rattle, but a possible vibration. the last sports cat i had fitted was knackered due to paste infront of it..may have been my fault, may have been the fitting garages, not sure.

the new one seems fine, only "vibrates" under load, really really sounds like a blow, but ive used 4 whole gaskets between downpipe and cat, plus flange sealant suitable for manifolds, and i dont think it is a blow. i cant feel any air escaping while im under it with the engine running. anywhere.

if anything, it sounds like this vibration is infront of the cat, in the manifold downpipe, which is a supersprint one.

im a little lost. it annoys the hell out of me. changes tone depending on whether cold or hot, and depending on gear, and only seems to be coming from the left hand side of the car, which made me think it was a blow.

really wanting some suggestions as to what to do. would heatwrapping absorb some of it? what can i do? the exhaust has cost me roughly £1000 in parts, plus god knows how much in paste/sealant at £5 a time.
