purchased car a couple of weeks ago and am replacing air filter and exhaust. which ones am i best going for without spending a fortune? the car is a uk tt on a j plate, has the exhaust got cats or can i take them out legally?

Hi,

 

As far as i know you have to 1991 reg or earlier (mine is 1991 H reg) to get away with no Cats/emission tests. I am having a custom full stainless steel decatted exhaust system made/fitted for £575 as a rear silencer has just gone. Just got to wait 2 weeks for it.. :(

 

Mongoose is a popular cat-backwards stainless steel exhaust system for aound £450 + delivery + fitting + vat... can get it from Zcentre & other dealers - look on traders forum...

speak to some of the traders on here for prices.

 

i like my mongoose exhaust, retains the quad pipes (only larger ;)), nice tone but not too loud.

also got a JWT filter which is basically a rebadged K&N. :)

Hi Marcus,

 

Cats removal: if your car was built during or before 1992 then you can legally remove the cats. Take note though that this may result in heavy smoking from the exhaust due to the rear turbo seals leaking (remove cats = reduced back pressure).

 

Airfilter: A'PEXi Powerflow is currently the highest rated airfilter (best filtration qualities and flow-through rate). I sell these at £100 + p/p but have a special on this week = £100 delivered to your door!

 

Exhaust: Mongoose is an excellent cat-back system which will retain the stock look. It is made of stainless steel, 2.5" bore and twin 3" rolled tips either side at the back. It has a very nice deep rumble and a lot of people are very happy with the system. Note: a Mongoose system is cat-back only and you'll need to get decat pipes if you're removing the cats. I am a Mongoose dealer and can sort you out with one for £510 delivered to your door via next-day delivery. All you need to do is take it to an exhaust fitting place and that's that!

 

Hope the above has been helpful in some way.

 

Regards,

 

Danny

thanks mate, is there any way of stopping the smoking? bigger seals on turbos or somthing?

Marcus,

 

As it concerns the rear seals on the turbos it is a real b*gger of a job to do. The turbo's are difficult to get at even if the engine is out of the car and you're standing next to it, let alone if the engine is in the car! From experience I would say that it is not a job you can do without taking the turbos off the engine block. However, whilst they're off the car you might as well replace them for uprated turbos, like the hybrids Smithy sells.

 

Hope the above helps.

 

Regards,
