Decat being fitted today
« on: March 01, 2012, 08:33:48 am »
Getting this fitted today (not actual product in image)



Just a little anxious about how loud it will be - It is used so I am hoping the carbon deposits will hell make the exhaust sound a little quieter as its been "broken in", mated to a resonated milly should I be concerned about drone or waking the neighbours at night?

Also - has anyone had any experience with sound deadening or insulation to help eleminate road noise? e.g. when your driving on a motorway the noise you get inside the cabin from the wheels and passing cars when your passing other cars.

Thanks in advanced

what make is that?

Noise from the decat won't be too loud (amount of noise does depend on the wall thickness of the tubing)

its this one here http://racebits.org/index.php?main_page=product_info&cPath=2_100&products_id=362

its not actually that one though, there isn't a makers stamp or identification on mine as I bought it second hand but it looks like a magnex one or similar, feels very well built and weld marks are very well done. the walls seem reasonably thick, not too thick but then not thin enough to make me worry about how strong it is.

I might heat wrap it when I get it home, I've heard that can reduce some of the noise (dont ask me how - something about reverberation yadda yadda yadda)


Oh, Do you supply revision D valves by the off chance? or have any lying around?

 :evilgrin: I might end up going that way but I think the motorway driving etc will prevent me. Iv done the whole v.v.v.loud exhaust before and loved it for the first few months then wanted to kill myself afterwards! funny thing is it stayed on for 2 years  :signLOL:

just popped round to see the ol'girl and what they were doing to her. well she's on the ramps just not had any work done yet - his starting now and said he just wanted to double check that i understood i was about to loss the cats and a light will come up on my dash. I cannot believe how skinny the normal pipe is and the first cat seems soooo small! It was really rusty as well  :confused:

just one other question he asked if it was alright to use the same gasket, I presumed it would be? or won't it? it'll have to do for now..

It's fine by using the old flansh gasket aka dp gasket ..aslong as it's not whopped..

How much difference have you noticed in the way the engine performs? Do you have any lights up? Seems like a really cheap option considering what the other brands are asking. Do you have any feedback on the installation, any issues?

I never had any issues with lights before and after mapping. Pretty straight forward enough to fit just ensure engine is stone cold before trying to undo studs. :happy2:

Same here  :smiley:

Not to noisey when you don't want it to be, but when you open it up it sounds well.

Engine light on after 100 miles
