rudedubber 0 Posted October 14, 2004 Report Share Posted October 14, 2004 ok before we start, I LIKE LOUD i have a hole in my centre 'suitcase' so want to replace the whole system but want to know what my idea will do to my car ? ok i have bought a remus back box and am thinking of getting someone to make me a pipe up straight from the cat to the backbox. (i had this done on a 325i bmw sounded nice) i am also hoping to get the cat removed but made replaceable for mot time. will doing this cause any running problems or loss of power/torque ? your thoughts are welcome and yes i know it will be loud thanks in advance Link to post Share on other sites
DundeeDub 0 Posted October 14, 2004 Report Share Posted October 14, 2004 i don't have a cat in mine anymoer, but its not loud cos the company i used build a box instead of just a pipe, as for power etc i have noticed my mpg being very slightly better and for running i have found no problems yet but i have only had it 3 weeks Link to post Share on other sites
rudedubber 0 Posted October 14, 2004 Author Report Share Posted October 14, 2004 do you only have just the backbox tho as that is what i am getting at, the backbox will be the only silencer the rest will be straight through pipeing ? thanks[ Edited Thu Oct 14 2004, 05:54PM ] Link to post Share on other sites

I think you'll find at you may gain a few BHP but lose some Torque due to the loss of back pressure. Link to post Share on other sites
gazbrook 0 Posted October 14, 2004 Report Share Posted October 14, 2004 when you say straight through do you mean with the centre section taken out, if you do then mine has that, i have a full scorpion exhaust and it was quiet with it on so powerflow took it off. In my opinion(not everybodies) it sounds amazing an v v loud, i do feel like its lost a tiny bit of acceleration but possibly gained more midrange and top end. Its all made up for by the sound,the only time it annoys me is when i'm cruising in one gear and the constant drone gives me a headache.Easily solved by dropping it down a gear and giving it some every now and again Link to post Share on other sites
dubloke 4 Posted October 14, 2004 Report Share Posted October 14, 2004 i have a scorpion on mine but it has no centre box, just two rear ones and its far from quiet! get louder the warmer it gets! Link to post Share on other sites
rudedubber 0 Posted October 14, 2004 Author Report Share Posted October 14, 2004 thanks for the replies guys. i dont think i have explained myself very well what i want to do is decat and then have no silencers at all except the backbox, so it will be completely straight through with only a backbox Link to post Share on other sites
dubloke 4 Posted October 14, 2004 Report Share Posted October 14, 2004 loss of torque, and very raucous i'd imagine! have to be carefull it will pass a decibel test if you're pulled too! Link to post Share on other sites

DundeeDub 0 Posted October 14, 2004 Report Share Posted October 14, 2004 i have no center box but a small front box and another where the cat should be (removable so can add cat for mot)Doesn't sound much louder apart from start up where you get a nice note Link to post Share on other sites
Macca 1 Posted October 15, 2004 Report Share Posted October 15, 2004 I have only a backbox, it is straight through from cat back. sounds great, with loads of popping. Id imagine without the cat it would be louder, sound awesome, and there would be a decent increase in power (5-10bhp), possibly a reduction in torque? not sure about this.

mark@vagworx 0 Posted October 15, 2004 Report Share Posted October 15, 2004 When talking to Nik Saran, he said that the VR6 exhaust is unbelievably restricting, so less is more! However, you will lose torque with having a straight through one box system. Link to post Share on other sites
rudedubber 0 Posted October 15, 2004 Author Report Share Posted October 15, 2004 hey so many replies thanks alot guys, i just wanted to check really. when i did this to the bmw it didnt make much difference to the performance but it seemed to use more petrol, but hey everything comes at a price like lowered cars and speed humps :? incidentally the bacbox i brought was a remus stainless of ebay, brand new delivered for £160 i think its like vdubgirls.

eViL 0 Posted October 15, 2004 Report Share Posted October 15, 2004 Noticable loss of torque down low with the charger on, which I don't like. If you are running a Schrick I guess it may be a different kettle of fish though. Link to post Share on other sites
