ive had a second decat put on today (the middle section on a 97 2.0 sport) and it sounds awful, far to much baffle?? the 1st cat was taken off before i had the car so i dont no what diffrance that made to compare it to??
so is this a common problem or simply a faulty decat???

many thanks.

 

describe the noise it makes? shouldnt sound awful and its a better free flowing exhaust with no cats in it better power gains and it sounds like its a faulty decat if you say it sounds awful either that or your too fussy

 

lol its not a blowing sound like its got a leak, its more like a old motor bike, its started poping when im slowing down which i quite like but when i put my foot down its sounding very ruff, when it only had one de cat it sounded very smooth although it was still agressive sounding? im sorry, i cant think what to compare it to, its a shame i cant record it?

 

its not a de cat like you could buy off ebay, i had a pipe fitted to replace it by a powerflow dealer? so its been welded on rather than fitted with spring loaded joints/ fittings? dont no if that would make a diffrance?

 

i think its maybe you are not used to so much noise try get a video clip sometime

 

has it made it sound very tinny/rough sounding ,the girlfriends sport sounded like this with the afterburner bk box fitted on her sport ,it sounded even worse when it was cold .i fitted a ninja back box and made the sound deeper,i have always found stainless has a tinny noise any how.do you have the unequal length headers on too

 

okey doke, il tru do it tomorrow, it just dosnt sould healthy to me, if another car drove past me soundin like that i would cringe!

 

yes it has made it sound quite tinny, il try get a vidieo clip of it 2morow because i cant realy explain how it sounds? almost like its popping but the repatition of pops is alot more frequent and the horrid sound only crops up when i accselerate? its started popping (normaly) when i slow down which dosnt bother me, and yes it has got unequal headers which gives it a unique sound but this dosnt sound like any scooby ive seen!

 

have you bolted a turbo system onto the sport system as these are 2 different sizes ,also check the headers where they bolt onto the head as the threads on the sports a very weak and they might have disturbed it so its blowing a little,


my advice is put the cat bk on,get a custom centre section made up so it mounts onto a turbo 2 1/2" back box and go for a scoobyworld racebox or ninja and you will get the sound you are after it may help to wrap the headers too ,you just need to dampen the sound a little

 

its not got a turbo on it? and the decat was costom made at a powerflow dealers? i was told that if a put a turbo on it that i would have problems with the head gasket as the engin isnt designed or tuned for that sort of bhp?
