Adding to a Cat-Back Exhaust
« on: January 08, 2013, 09:35:34 pm »
Thinking about getting a remap in a few months and was thinking is there anything i can do to my Blueflame Cat-Back non res to make a few more BHP and move free flowing. I no i should of gone for a TBE but couldnt afford it at the time, and find them a little to loud for daily driving.

Would a downpipe/sport cat help?
Also would it give a more of a 'burble' or 'pop'


Any feedback would be appreciated :happy2:

An easy quick mod it to remove the downpipe and knock out the Pre-Cat, search on here for it. Easy as hell to do and that free up 3-8 BHP and sounds a bit deeper, also turbo spools up quicker  :laugh:

I havent as of yet. It seems a simple mod for a garage to do and seems everyone has has good benefits to doing it. But would i get the same gains as to getting a downpipe with sports cat? if i were to go to stage two would this still be ok with the pre car removed?

Just cant afford it all atm with insurance and mot next month. Would it be worth just getting the sports cat for now and then when i can afford it getting the tbe. Would there be any gains to getting it before the full tbe

If you just get a downpipe and sports cat this shoud bolt on to your current cat back exhaust an then you will have a TBE.

Will need a donpipe and sports cat to go to stage 2.

Make it sound so simple now.  So if i add a downpipe and sports cat it becomes a tbe. I thought you had to change a few other bits. Can tell i dont no exhausts very well  :ashamed:

I am hoping the go to stage 2 eventually :happy2:

This is exactly what I did with my exhaust...

had a milltek car back fitted, then a few months later went for the pre-cat delete..however this didn't go well so ended up getting custom made downpipe plus 200 cell sports cat added = TBE  :happy2:

How did yours sounds from going from cat back to adding the downpipe and 200cell sports cat?

Does it matter if i dont get a blueflame sports cat? Assuming the pipe will be the same size.
