Hks Silent + De Cat

imi · August 28, 2009

Well i bought the HKS Silent exhaust for the IS200 from Daz (thanks) fitting is on Thursday at Glossop, also the Coilovers too.

I used to have the HKS-Ti on my previous lex which had a nice rumble, not too loud and not too silent.

My questions are:

1, Whats the sound like on HKS Silent power as it is with silencer connected to it (ie the extra piece on the back box)?

2, How loud would it be if i removed this extra bit on it?

3, How loud would it be if i De-Catted the car aswell?

4, How do i go about getting a replacement section where the Cat is currently situated?

5, How do i get rid of the dash board light that will come up if i decide to de-cat?

thats all folkes... input appreciated..

you may run into emissions problems if you de cat the car all the way through.........

I was told VOSA are getting exxcitable about emissions and doing spot checks

if it was me i'd get rid of the pre cats in the manifold and try to source a hi flow cat for the main cat

Pre Cats have already been taken out by steve at Glossop, just thinking of taking out the main cat and replacing it with another pipe like SparkyStav has done, so at least i can put the main cat back on if need be for the MOT.

Sent you an email regarding the 02 simulator needed when cat has been taken out.. (will be supercharging when i have some £££ soon)

I don't sell them individually I suggest you have a look on fleabay .

you should be able to get a section to replace the cat easily.

I use pipe_werx from Ormskirk (again on fleabay) to make up bits for me they may be worth a shout

OK thanks, i've contacted a local place that make exhausts, they said they can make one for me, will see what happens

will look on fleabay for simulator..

Easy mate, just in the process of replacing my Cat. Found a place that can do a replacement stainless steel one for about £80.

Let me know if you want details.

As for warning light, I don't think you'll get one as my Cat has blown, and i'm getting no warning on dash.

And there are no sensors around the main Cat either.

That is good to hear mate, that you are not getting any warning lights

thats weird, i get a light coming up on the dash every once in a while, had it checked once and it was the main cat sensor, i just reset it by taking out the EFI fuse for about 30 secs and it disappears..

James, PM me the details and will definalty look into it, the place i had in mind are booked up for the next 3 weeks..

This happened to me. This seems to be usual behaviour for failling O2 sensor. I had the sensor replaced and the engine mamagement light has not appeared since.
