Blue flame dp vs milltek dp (high flow cats)

[Craig!]

The stepdown will cause backpressure, however a turbo car doesnt need too much back pressure at all but some helps.

So would a 3" d/p be well suited to a 2.5" scorpion cat back?

Yep, both Blueflame and Miltek are 2.5" cat-back systems so I cant see a problem with it. I know Mike @ A&M runs a 3" DP into a 2.5" cat back.

Just what I wanted to hear

iv got a modded 3"DP to milteck cat wich im sure is a 100cell then 2.5" cat back and it works very well, i noticed a differance when it was fitted, spooled up quicker and held boost a tad longer

Apologies from dragging up a thread from the dead (thought it would be better than starting a new one)

I'm debating spending extra for the Milltek at the moment, is there any major difference noise wise between the Milltek and BF?

I cannot stand loud or overly drony exhaust, I used to have a Supersprint system on my Polo and that was really classy and not intrusive!

The other option is BF turbo, cat and mid and S/S backbox... Really confused as you can tell!

to my knowledge neither are overly loud. i have a turbo back milltek system and it does the job, it sounds good, it pops and bangs occasionally, not droning but if you boot it you got a tone. idle note is louder than standard, especially when the secondary pump has kicked in.

while driving around casually people have commented that it sounds standard'ish'. but revved properly it sounds sporty

i have the milltek cat and D.P amd the scorpian cat back system and mapped by apr noticed a big differance with fitting the D,P and cat.I was tod that the cat back scorpian systems are only b2 inch though

When you fitted the downpipe and cat did you notice an increase in sound ?

i have a scorpion cat back system at the minute and i am thinking about getting a full blueflame turbo back system after christmas but i want an exhaust thats quieter when driving my car normal than my current scorpion system, has anyone gone from a scorpion to blueflame ?

 

[bucky boy]

cant say ive noticed a differance in the noise to be honest mate.

What one you got the STW or Tuner mate.

Mine is a tuner, but I only know this through research as I got it with my car when I bought it, have been looking to couple it with either a blueflame or a miltek since.

I found a scorpion cat back with the stw on ebay thats still the 2.5" though even if it is the diagram for the single pipe instead of the twin (which i think is the only diff?).

 

[bucky boy]

see thats what i yhought but when i got my d,p fitted a reducer had to be fitted and he said that it was a 2" pipe and not 2.5" going to have a better look later today.

 

[pdcupra]

can you mate a blueflame downpipe and 100cell cat to a milltek centre section and backbox?

 

[Deleted member 9043]

jes you can


and do you get any gains of replacing the cat of a miltekk dp to a straight pipe? with k03s turbo

and does the sound gets verry louder with this mod?
