Hektik,
Don't bother going to an exhaust shop, take it to Protek in Preston. An exhaust place will charge you through the arse and will probably be a bunch of arseholes to boot.
Get this. I bought a new oval muffler to replace my cannon (wanted something a bit quieter). I called up a "reputable" muffler place (won't mention the name) and was told to bring it in. I get in there and suddenly it becomes all too hard. "This is gonna take at least 1.5-2 hours" ($95 an hour labour). "Turn the f*ckin immobiliser off" ("How do I do that, I ask?) "I don't give a f*ck, just turn the c*nt off, they're a f*ckin pain in the arse" he says. "We'll use 2.5" pipe to connect it, we can't bend 3 inch" and finally the clincher "I can make $100 in ten minutes, i'm not gonna f*ck around with this thing for an hour".
After all this, I just told him that I would take my business elsewhere because he's a f*ckin shit bloke and went I to Protek in preston where it took them less than an hour and cost me $88 in total. I don't know why I didn't consider them in the first place, it's the only workshop i've ever taken my car and they always do a great job. Furthermore, they used 3" pipe on my 3" system, and not 2.5" like the other dodgy place were going to lol.
I'm sorry for that rant, and the language, I'm still angry about the whole thing. Especially because my car decided to lock itself in the driveway of the exhaust place with the keys in it and I had to pay $110 for a locksmith to come out and unlock my car (took him a total of 15 seconds lol). Worst. Day. Ever.
Again, sorry for the rant.
In conclusion, Protek all the way.
