Title: Replaced downpipe now not making boost?
Post by: Vitamin_p on April 29, 2015, 10:52:17 pm

I just replaced my downpipe due to blowing on the flexi pipe, now it's not making any boost. There is a whistle but no boost? Can anyone throw some light? Thanks in advanced!

UPDATE!

Cut out the cat and welded in a straight pipe and making full boost again! Feels and sounds great

What will you do come MOT time? Put the standard downpipe back in?
