Hi

I have got a chance to aquire a used decat twin dump T75 downpipe for my 97 uk turbo.

My questions are

Is this exhaust a good option for a first mod, to followed by others later on ( I would like about 280power/ 280 torque).

Can I run this exhaust on it own to enjoy a margin of performance increase before I have my next upgrade, with little risk of overboost or knocking (fuel is optimax)

If there is the likelihood of overboost can I use a MBC to keep boost to normal levels before I move onto an APEXi FC (mapped of course) and new vf34 later in the year.

Or should I just wait and have all the mods done at once to coincide with it being mapped.

opinions please

Andy

 

be easier to get it all done at once bud,,,,but you'll get away with a down-pipe while waitng for the rest and mapping . .
getting rid of the 'big' cat should gain you around 12-18 bhp,then fully de-cat it and probaly go upto around +25 , ,
