au xr6 exhaust mods

[xr62nv]

thinking of getting an aftermarket exhaust, with some extractors and a high flow cat.
How much should i be looking to pay? i was quoted $950 from liverpool exhusts in sydney, seemed cheap not sure if its good though are there any particular brands to go for? what else should i be asking this exhuast place?

Also does anyone know what sort of rwkw/performance gains i can expect.

$950 is a fairly reasonable price.
Make sure its all mandrel bent 2.5inch or 3inch.
Find out the headers they use?
Most common on here are the pacemaker comps, difillipo are top of the list aswell. Both have netted decent power gains and are on all the top running cars.
Gain anywhere from 5 - 15rwkw. Depending on your cars standard tune and 'health' of the motor.
