Below is the finished fitting. Looks pretty stock still, I think.

Performance wise, I noticed the following:
1) sounds a little more angry / aggressive under full throttle
2) between 5,000 and 6,000 RPM it pulls stronger than before
3) gear changes feel stronger for 1st - 2nd and 2nd - 3rd
4) wheel spin in 1st is a little easier too
5) flooring it when cruising at 40mph, gives an improved "push" and it really goes for it, even better than before (which was good anyway)
6) slight increase in the sound from the supercharger

All in all, I am very pleased with the mod. WOT is where it seems to make most of the difference. I would guess it does reduce the 0-60 slightly as it does feel noticably quicker.

So the Butt Dyno says do it !

 

You certainly were able to maintain the stock look. Looks great!

Nice mod on the blower cover. Where did you get that new SRT6 engine plate? LOL.

 

It is rather nice isn't it ???

I also painted the rocker boxes to match (did those about 8 months ago though). Just goes to show, one of your engine plates was always destined for my car. The SL55 pipes went in really easy, I recon could swap them out for standard in 15 mins now for servicing / warranty work.

How long have you had the pipes in? Did it take long for the ecu to adjust to the increased airflow?

 

Fitted saturday AM, went for a quick test drive. Felt slightly better. Took it out for about 40 miles sunday and felt much better. Only done about 50 miles since fitting, so I hope it still improves further. I won't get the chance to "rag it" now till the weekend.

 

Nice pictures - Your installation looks very clean.

 

Thanks, It didn't take that long either, quite a simple / straight forward fit.

In the end I unclipped the airboxes, after offering up the Y pipe assembly and marking the pipes with the top of the airbox moulding line, then fitted it all together as one assembly, lining up the pipes to my marks. After that it just all went into place with no problems.

I used stainless steel inside the pipe to clamp down on, it was no thicker then 0.5mm thick and cut to about 18mm wide. I was able to "shape" it oval to match the airbox and clamp it firmly too.

I hope your install goes as smoothly and look forward to hearing what you think after.
