Ive got some new 195/50 P6000s that are going on the car as soon as I get it back. Ive been driving round on bald tyres with slow punctures up until now. Cant wait as the handling is pretty spectacular on the slightly skinnier and totally shagged 185 tyres.....whats it going to be like when its running right?!
Ive got a Hill Power De-Cat on mine and it made a very noticable difference. The car seemed to pull away alot easier and it did free up the top end quite alot too. I would say it is probably one of the best value mods i have done so far.
hehe well ithink my r/r results speak for themselves lol
de-cats do work
ive got a devil decat on mine but must admit that the power suffers a little low down, and seems to pull thru the lower revs a lot faster with the cat on.
but with the decat on and normal driving(for me lol) above 4k rpm it feels a hell of a lot better than it does with cat on. tested within the the last couple days, altho it is quite a bit louder too but theres always some penalty to pay for power hehe
Id just like to point out that Ive also got head work and cams - as well as a de-cat! So Id be expecting to make more power anyway (although I think my engines running rough at the moment - another story).
I fitted the de-cat a day before the RR day and its difficult for me to comment on any performance difference as I hadnt driven the car in a couple of months before I put the de-cat on. What I can tell you is that its noisy!!
Id take it straight off if I was commuting to work every day in the car or if I did lots of slow speed/round town/motorway work. In those sorts of situations it makes the car sound a bit Nova-esque. But if, like me, you drive the car purely for recreation on quiet country roads, its fine and adds a little poke at lower revs (on a Valver anyway). It also spits flames; I never saw the reason why the Mongoose exhaust systems tailpipe extended so far from the bumper - now I do, it saves my bumper from melting!
Hmm....might go for a silenced de-cat pipe as suggested. Also, http://www.fastchip.nlwww.fastchip.nl do a chip for £230 that includes a basic launch control feature, programmable change light and full throttle gear changes. Says it is only for "Phase 1" at the moment, so Ill have to ask them if itll fit to a Willy 3, but def. sounds promising.
I bought my car with the decat / filter already fitted, so cant comment on any performance difference. I can however say my car got 163bhp / 141lb ft torque on a rr, so would imagine the decat made most of this difference. SOunds sweeeeet as too.
I have got the Hill Power de-cat - and my exhaust also makes that annoying buzzing sound at 3-4k revs. The rest of the system is std.
Would fitting a Magnex cat back exhaust cure the buzzing noise? It really is becoming irritating, but i want to keep the de cat cos the car seems more repsonsive (that could also be due to the Stage 1 HP chip and Induction kit though!).
I had a de-cat on my old valver, but that was with a Scorpion stainless system and I never had the buzzing noise that I have now. Any thoughts?
