i run a completely de-resonated system on my wrx which was done after my car was mapped,no problems at all and it pops and bangs too, take your car to a custom exhaust place and get them to cut the boxes out (not the cat unless or you will need a remap) or search on ebay for de-resonated cobra exhaust,think they are about £112 just remove your center section exhaust and fit one of them

next step is the extreme end of the scale where the back-box is removed aswell

You can buy a straight through centre section (de-res) and a decent back box if you haven't already got one, that will increase the burble drastically. Going further than that, the up pipe can be changed for a straight through also which won't require a remap. However a map tweak will free up some horses if you did decide to go down that route.

If you just want pure air filter noise you can fit a induction kit but not advisable IMO unless you are going to do a remap, as it can cause the maf to play up. A decent panel filter should still give you an increased sound ie, green cotton.

This is the Rolls Royce of 'loud' exhausts.

Wow they sound awesome, iv herd a couple of scoobs like that but didn't really no what made it, is de-resonating just removing the exhaust baffles?

K913 have you got a classic or newage? I've got a Classic titanium Kakimoto straight through cat back exhaust for sale. It is one pipe straight through to the back box and sounds exactly the same as that, it sounds amazing, best exhaust I've heard. £120 if you want it?!

Yes you do if removing the cat in the uppipe of a wrx for a Sti item it SHOULD get mapped, others say it runs fine and they may well do, but for the sake of a couple of quid I'd rather know my car was right and actually benefitting from the mods done rather than possibly not making any difference or even loose power which has been known before now and can cause engine problems

well i booked in at pro speed they said they can fit a straight through mid pipe for 115 which sounds ok . but will be leaving the up pipe as they said could cost around 150 just to fit shame really but never mind unless any volunteers who like to do freebes because they get very bored lol

I had mine changed to a decat when the cat pipe broke its welds (which they often do) and it was fitted and supplied by Scoobyworld. I did ask weather or not a map tweak was needed when fitting it and they said it would be fine. Yes you get more benefits for having a remap after but there's isn't any down sides to not having it mapped. And it's not a "couple of quid" to map after, a first map will set you back between £350-£500 depending who you use. I would change it personally, at least you future proof it and have piece of mind that the cat won't break apart and destroy the turbo. Speak to any number of the Subaru tuning companies on here who can help.

ok thanks the only problem is it costs a bomb just to get someone to fit the up pipe which is a pain and regarding the remap ye they are expensive i think they greedy how much they ask personally even when you have a few to do they only drop the price a little for such little work they do .

Well each to their own and all that

Cost of maps do vary but if you wanted to go o/s rather than ecutek then you can near enough half the initial mapping costs, and I would still say it should be mapped when you remove the cat, we have been quoted £250 for an os map and to be fair that I would say is more than reasonable considering time involved, start a thread "if I remove my cat will it need remapping" as I'm sure you will get a lot more telling you to do it than not, but like I say people do just remove them and some probably never have issues, but when you weigh up the cost of a remap vs new engine plus all the labour charges, gaskets, oils etc then it really isn't that expensive IMO for piece of mind

When you say pro speed is that Cardiff? If so your local to me and more than willing to lend a hand if needs be

It costs more because you have to remove the turbo.

Not something I would try, and worth £150 to get a specialist to do it. Gives a great induction sound once you change the standard one.

I would be happy to pay 250 i just think 350plus is alot. And yes i do agree if for peace of mind i would prefer to remap if it could cause engine problems.

You'll benefit more from changing the centre section and backbox buddy. My 03 wrx is completely decatted now with a prodrive backbox.

I use my car everyday and have my 2 daughters in it aswell so it offers the best of both worlds for me, quiet enough when not putting the hammer down but it does roar when pressing on.
