Hi cerealsurfer, I was looking at this pic, and it just occured to me that the outlet pipe looked too clean, so I went into my garage and proceeded to wipe my finger on the inside, and as expected my finger was virtually clean, does it mean its running too lean? Is that normal for Aero?

Yeh.. in addition the headers are double skinned... (the pipe you can see is only the outer one) and so the internal diameter is only about 0.5" !! AFAIK.

As for other construction issues... take a look at this link of the 4.5 AJP aftermarket manifold (which has been made for peak power of ~400-450bhp) Check out the length of the primaries and secondary pipes.

All modern engines run a little lean.. it's the ECU trying to save fuel and meet smog rules.

Hear hear

When you get it sorted Kin, you'll have to start the Northern equivalent of this:

London Tunnel Run

:cool:

LOL There're a couple of short ones around Manchester Airport, but for the half decent one, I might have to go to Liverpool's Mersey Tunnel for it.

Have my exhaust made today, when I first saw the silencer, I was very concerned as it was less than half the size of the original, thought to myself I've just wasted £300, its going to be too loud...



I assummed it was a straight thro., then Rick show me his design which was exactly identical to my sketch



My main concern with the sportpipe is its bassnote and rumbling sound may transmit into the interior and ended up boomy and intrusive and ultimately tiring if you travelling over long distances, I took that chance and glad to report that there was no boominess in the interior during the 1 1/2hr drive back.

Soundwise....At idling, its quite, very slight rumble(bearly detectable), but as soon as gas is applied, the sound it emits can only be described as music to the ears(cliche I know), it just woofles with a nice clean bass, pops and bangs were more obvious and slightly louder, under hard acceleration, the bass note seem to have disappeared and was replaced with burbling/flatulent sound (the flatulent sound was less obvious at low speed than the std sidepipe).
There were no discernible differece at motorway speeds on part throttle.
I'm well please with the result considering this was JP first attempt, its louder overall, but for all the right reasons
Price? £150each

Cereal, I asked Rick about your header, he could only give me a rough estimate £5-£600 each side

Interesting cars at JP today

Paris Daker off roader (20 of them )






A formular Ford?


...and a chav mobile

Simon, could you blankout the plate for me please(I forgotten how to do it )

I'm pleased to hear that you are delighted with the result Kin, when do we see a photo of it in situ? But, even more importantly when will you post a recording of it at different revs and/or speeds?

Do you have any idea what the maximum sound level is, were JP able to measure it, will it preclude you from track days? It does not seem overly expensive and I am sure that some other Aero Side Pipe owners will consider following your lead. Well done.

Heres a photo of it in situ.


I have no idea how to post sound files
Regarding max sound level, think even the std sidepipe would have problems with most trackdays
