Custom exhaust

[Kendy90]

In need of a very fast reply as my car is in this afternoon!!
This afternoon I am having a custom exhaust on my PD170 FR, complete straight through system and they have given me the choice between 2.25" or 2.5" pipe, I know the non resonated milltek systems are 2.75" so I was edging toward the 2.5" but everyone I have spoken too is telling me to go for the 2.25" as the 2.5" will put too much strain on my turbo etc... Has anyone had any experience, also if I do go for he 2.25" will it restrict anything when I then come to mapping it in a few months time?? Thanks in advance

Bigger is surely better on a tubocharged? Within reason lol

 

[Kendy90]

That was my thoughts, less restriction for the turbo?

Where you having it done at?

Am I not correct in saying that a diesel works well with pressure so I think the smaller the pipe the better? May be completely wrong but I am sure I seen this somewhere.

Having it done at a garage called exhaust a fix in Darlington

This is why I needed advice... Confused now haha

Don't take my word for it but I am sure this is the case until you go down the hybrid turbo route but I am sure someone will clear this up.

I been told tdi still need abit of pressure too

Went for the 2.5" in the end, they have done a great job but car doesn't sound any different!! Need the DPF out as soon as possible

I had a straight through and it was fine on both diesels

I don't think the exhaust note will change at all, I've got my dpf removed and it still sounds the same.

Was hoping for a bit of turbo noise with a complete straight through and no DPF?? Have you got any silencers in your exhaust??

 

[Dodsy]

rear backbox is still on but these engines need a bigger downpipe for the exhaust note to change significantly or so I've been told. I'll be looking to remove my backbox soon as it's had it's day so if your getting your dpf removed anytime soon post up a video of the noise as I'm quite keen to hear how it sounds.

Okay I will do, it won't be any time soon like because you need it mapping out and I'm still saving and looking for a decent mapper that's reasonably priced!!

 

[Dodsy]

How much did you pay for your exhaust if you don't mind me asking? Have you got any photos?

Cat back system, could choose the size of piping and whichever tailpipe, I payed £220, will get some pics posted later today
