yup thats your headers, if your lucky its the gasket, unlucky you have a crack. Dont get the silver looking perforated gaskets they are dog poo, get the genunie ones or ones similar

Have you tried selling them on ebay

Sorry headers means exhaust manifold, it sounds like its blowing where it meets the cylinder head, also check your spark plugs are tight.. if you have swapped plugs recently one may not be tightened up enough. First test jack the car up, put it on stands, handbrake on out of gear and start it up, have a look and hear by the manifold, if it is not there try the plugs. Your to far away for me to pop up and check for you

I had a blow from my passenger side header sounded like that, but alot quieter. Mine was a gasket issue, yours sounds like its possibly cracked

more I hear it i recon its headers

sounds like broken headers, hear it on blip of the throttle? if its big ends its usually there on cold start and hits loud at 2.5k onwards

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=201666644242&ssPageName=STRK:MESE:IT#ht_500wt_1414 mine are on ebay

They are Rota grids in drift bronze 18 * 9.5j fat as foook

Thanks they dont catch at the moment, I have to get coilovers, arches rolled and camber to make sure all will sit nice.

Treaded myself to some 18x9.5j rota's and a splitter

Jack the car up, put on stands, drivers side of the radiator (bottom) there should be a drain plug, get big container to catch old stuff, make sure its cool, take off expansion tank cap then undo the drain plug. once its all out put plug back in and refill.

Sounds like a lack of coolant change, more than likely rust and deposits gathering, people before could just use tap water as coolant, best bet is dont use engine flushes as they take out weak gaskets, but empty system, fill it with water and run for 10 mins, cool it down, drain it and fill with proper coolant, give it a few hundred miles then drain and swap, hopefully this will have cleared any coolant abuse

what server are you on?

they work ok over 300bhp, no reason not to have one if u want it but would recommend a rr check to make sure fuelling isn't to messed up

every car is different, it will not be set to yours the best, if your lucky it will run a little rich, unlucky and your lean. Please just save and get it remapped propperly

silly question, did you have the error codes reset as it will still show

if you kept the old bits I would swap them back 1 by 1 and see if 1 makes a distinct difference, cheapest way at the moment

pictures and price please

They will be ok for a few thousand miles but would need replacing soon. £650 COLLECTION ONLY. I WILL NOT SPLIT SO PLEASE DON'T ASK

What about "Federal 595 RS-R" they look good and are a reasonable price from most places like Camskill. Thinking of getting a set for myself

Very Nice, just one thing you got an up rated top mount intercooler not a front mount, but still nice power

That sounds like its coming from the turbo itself. Turbo shot like sav said

I've not noticed any issues with mine so far. Aerial's are about £20 new from Halfrauds. Its just hassle fitting it.

easy way to see if it needs just a re-gas, pup the pressure switch off the pipe work near the rad, short out the 2 pins with a bit of wire, start car and turn on the ac, if the clutch engages then its low pressure meaning try with a regas and pressure test

Seen this done to a 2016 sti last Saturday, it was stupidly loud. was at scooby clinic and their opinion was that due to 0 back pressure this would actually reduce the performance.
