    The main problem with the cheap exhausts is the noise, some sound awful and drone when cruising. That is part of the reason the expensive ones are expensive.

    I bought a cheap stainless one for my celica T-Sport off ebay around 4 years ago, I suspect it is the same one you will have bought as they still make it now.
    For the money I cannot fault it, not stupidly loud on the motorway and if you do find it too loud my one came with a bung which made it only a little louder than stock, I'm very happy with it, looks great, good quality and so much cheaper than a custom made one.

    it will be power flow. There as good as the guy fitting it. if you plan to go custom replace your rubber hangers, some people keep the original rubbers and they don’t hold the weight well and I have to pack them with Tyre valves and zip ties to try and restrict movement.

    If your not chasing big power then power flow are good but if you’re after 800bhp from a 1000cc 3 cylinder go elsewhere, power flow don’t supply inserts to stop the bender from crushing the pipe so it looks like the bends on a std mild steel pipe

    Flow will speed up slightly though the bend and slow back down as soon as the pipe opens up, there is no restrictions.

    Any restrictions would be at the box were they have used a box with a smaller dia hole because they have non in stock

    Flow is different from speed - an exhaust made of bends wouldn't flow better than straight pipe

    and secondly I was taking about crush bends - ie. not mandrel bent

    you said the crush bends restricted performance. Crush or mandrel the difference in flow is little you won’t even notice it.

    But as a whole system vs stock system the powerflow will flow better and for a road car crush bends are fine

    Bought this from ebay in the end:

    https://www.ebay.co.uk/itm/Toyota-C...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649

    It's basically a stock replacement (non stainless). Cost 30 quid to get fitted at a local garage - so £190 overall, less than 50% what the original garage wanted for essentially the same thing.

    Has a slightly deeper exhaust note which seems a little louder under acceleration.

    Will look at a full stainless system when this one drops off!

    Bargain, thanks for the reply. Was cautious of that one as it doesn't state the diameter of the pipe as the t-sport is bigger than standard. Did it also come with the chrome tip or were you able to remove it from the old one?

    I'm not fussed about added performance or more noise, if anything I find the stock exhaust a bit loud but then it is now about 20% weld paste :p

    Haven't had a proper quote yet though as it got through the mot, just getting noisier and it sounds like a heat shield has come loose as well.

    Not sure on the diameter, though they said they had no issues fitting it and didn't need any other parts so assume it's a direct replacement.

    Only downside was the chrome tip - had hoped they could swap it on to the new exhaust but it's spot welded on. I did take the old pipe home so will have a go at removing it and attaching to the new one myself. :D
