foreigner Mod question I have read so many posts about headers and air lids my head's spinning.
But I would like your opinions, you see I live in England and therefore have no access to any tuning shops. I have a bone stock '01 Firehawk and am looking at the LS1 package at Tbyrne, which consists of SLP air lid(no filter),SLP MAF and BBK TB for an approx 30Hp to the wheels.Also I'm thinking about headers but I have to be emissions legal, at least up to California standards and was thinking whether the MAC mid lenghts or Bassani mids both with catted y-pipes would give any gains especially without being able to tune it in.
Sorry for the novel but I want to be as accurate as I can with my question.
Thanks in advance.

Shorties will give you no gains over stock 01/02 exhaust manifolds. Mids may give 5-10rwhp. Didn't you firehawk come with the SLP Blackwing Air lid? Avoid the MAF. The stocker is good and aftermarkest just cause problems. As for tunning, if you have no tunning shops you can get a predator tunner and work with a mail order tune through Runninng with the Devil.

Thanks for the reply, I should perhaps stick to a lid for now( blackwing on '02 models) and a TB?
What about keeping the stock headers and just changing the Y-pipe for a better flowing unit?
Again thank you.

The y pipe won't give you much of an increase (5-10hp at best)
If you can you could get the long tubes, and HPTuners, and tune the car yourself.
Is the E test a sniffer, or a computer test? If it's just the computer test, just eliminating the codes with one of the editing programs would get you to pass, then the only other thing you'd have to worry about is a visual.

Aha, another Brit! you'd be surprised how many frequent these boards 
There's a couple of places that are doing LS tuning in the UK now, try...
http://www.xero-competition.co.uk/LS1/index.htm
or
GD cars import LS engines (http://www.lspower.co.uk/) and get their engines tuned by a guy call Geof (something, can't remember) down Northampton/Oxford way.
Alternativly drop a mail to HPTuner or EFILive and see if they have anyone over here doing professional tuning.
I wouldn't worry about the MOT test, get the right parts then get it tuned, I'm planning on running without cats and just flashing a lean tune for the test (still dithering over HPT or EFI Live though
)

Thanks guys for helping, and as far as the emission test it is a strict sniffer test which will fail anything that doesn't smell of fresh lavender!!!
I'm leaning towards the Bassani mids and catted y-pipe and perhaps an SLP Diablo tuner to try to keep the A/F ratio in check, and of course an air lid.
Thanks Happy Jim, it's nice to know I'm one of a growing number Brits on these boards.
