Hi
My car has been suffering from hesitation since I purchased it a few months ago. At about 2500-3000rpm the car would hesitate when the throttle was pressed and would then accelerate quite fast but not as fast as I would expect from an Impreza. If the car was held on the throttle at 3000 rpm you could feel the car slow down then speed up continually. At Abingdon the car was shown up by other Impreza’s getting 15 mph more than me on the straights. I took this to be the hesitation quite a few Impreza owners are talking about. The car came to me brand new with just a Magnex 6X4 oval backbox the rest of the car was standard (performance wise). I then purchased an ss downpipe but could not tell the difference between this and std. Thought the exhaust should be a little louder with the downpipe but it was not the hesitation seemed to be worse, Hesitating every time at 3000 now instead of every other time.
Today I purchased a new exhaust from Bob Rawle I took the exhaust to Bob’s local tyre/exhaust garage and had it fitted. (mid section and backbox) When driving home from Malmsbury I noticed the hesitation was gone and the car felt more like my old one, much more eager to rev. Took the car to my local lanes and gave it a good blast, what a difference I had been driving a shopping trolley for a few months and got use to it, now I'm back in an Impreza.
Don’t know if the problem lies with the cat or the Magnex backbox I was not looking to cure the hesitation with an exhaust I just wanted a better sound. But it is now gone and I am ready for another Exmoor blast.

hmmm, if you only changed the exhaust and got it all sorted then perhaps the old box or centre section was clogged up somehow?
I trust you bought the drainpipe HKS?....any other tweaks by Mr Rawle?

Take away 5-10 bhp and I will feel it the car at that time had lost a good 30-40 bhp.

I think it will be almost as good as my old phase 1 we will have to see.
Very happy with the car as it running now anything else is a bonus.
