Custom exhaust 335d e91

Has any1 on here fitted a cat bk full custom exhaust system for there 335d mines a e91 on 56 plate

I've booked mine into torque flow in Birmingham only heard good things about them ! Seen a few videos on you tube ! Some sound great some sound awful !

I think the stock setup even after dpf delete and remap is lacking in the exhaust area!

This is my first post on here ! Hello every1

You're in good hands with Immy at Torque Flow. I got a custom made 335 style back box made for my 330i with twin 4" tailpipes last year. He's a perfectionist and his work is spot on.

Bet the 330i sounds amazing !

He told me that he had invented something called a jet stream !

Meant to give the derv a nice sound with the 2 turbo!s I'm not having any back boxes I'm going from the cat back into 4 inch tail pipes !

I can't believe the price he's quoted me ! Especially the work that will be going into it ! I will post pictures when it's done !

I didn't want anything too lairy since I've got a little girl. Got it done last year and one year on it sounds better. A nice roar when you put your foot down.

The pics of what he done are in my build thread

How much is he charging you? And is it 4inches from dpf all the way back with no boxes?

Bet you're well excited. This is on my to do list as well, and will prob go to torqueflow too, only good stuff i've heard

I went with my friend to have a x pipe made for his e55 amg and was not impressed with there methods and quality of fabrication. Just looked cheap imo. Iv always used a professional fabricator in Litchfield on all my cars, iv spent thousands with him on previous cars and will always choose him again. Definitely recommend to anyone

I am to be fair ! It will be only 4 inches at the tail pipe I think it will be around 2.5 if I can remember what he said I might be wrong!

The engine has so much potential to sound amazing !the jet stream sound with the turbos the price is going to be between 350 and 375 !

Can't believe it's so cheap ! If I had back boxes it would be more money !

Looks fantastic on your 330i cracking motor ! I will post some pic's when it's done !

Cheers mate. You won't need backboxs with it being a diesel. Good choice on 4" tailpipes and can't wait to see the pics.

Thanks ! I can't wait ! Hope it sounds as good as that silver e91 335d on you tube!

That's what I'm hoping it will be like! He's had a similar system to the 1 I'm getting by what's he's said on the description !

I've heard mixed reviews about Torque Flow. Would be interested to hear your experience once done.

I've had full systems on my previous 330d and 530d but went with the likes of Milltek etc. Without going straight through it's quite difficult to improve the exhaust note of the diesels.

Had the exhaust done by imi yesterday ! Top bloke really took his time and involved me from start to finish ! Would Defo recommend him !

I opted for 4 inch tail pipes and 2 jet screamers that kick in at 2500 rpm !

First impressions is that it's not that different to stock loud wise the sound is very similar it's taken the turbo whistle away which I thought would still be there but louder ! The back boxes must help create the sound! The car seems to pull off the line quicker, the weight it's shaved off is impressive the back boxes and tail pipes must weigh at least 15 kg !

I was told by some1 that it will take a few weeks for it to bed in/exhaust fill with carbon so it may sound better get louder as the weeks go on !

It looks fantastic at the back now with the 4inch tail pipes ! not bad for 350 all in !

Over all very happy With the upgrade !

Yeah Defo ! I'm new on here so when I get time I will get a mate to video me got a lovely bit of road by mine that would be great to show it off !

As I said it's not as loud as I thought it would be ! I was expecting the dreaded turbo's whistling loud which I don't think is a nice sound !

I'm glad about that ! I might go bk in a month and get rid of A joint section which is half way down the exhaust ! Imi reckons another 200 so if I get that it will be 550 all in!

Defo more responsive it's worth it for that ! Al try and get a video up by the weekend ! I'm cleaning the car Tmr so will take my profile pic and pics of the car !

Glad it went well buddy. Immy is a sound bloke and as you said happy for you to watch him work and chat with you whilst he fabricates. The exhaust will definitely sound better in a few months time once it beds in. Looking forward to seeing the pics - start a build thread.

Thanks mate ! I will Defo do that ! I've done a few things to the car already and the previous owner as well ! I'm still getting to grips with the forum only joined last week !

The next jobs are in a month is to go back to see imi and go further back towards the cats ! Another 200 !

Getting my steering wheel done by Royal getting Alcantara and red and blue stitching !

Private plate/metal pressed with back plates !

Why does it take time for the exhaust to bed in? You would of thought it would sound as it should straight away !

Sounds like you had some nice mods planned. The 4" tail pipes is just a perfect fit for the 335 diffuser and fills it better than the standard 3.5" pipes IMO.

I think the exhaust just needs to fill up with carbon which only happens when the car is running and makes for a deeper note. Although don't quote me on that.

The previous owner had the wheels done And tinted also had a stage 2 detail ! The car now looks stunning ! I want to put original Bmw badges on as the previous owner put carbon 1's on ! I've de badged it looks amazing at the back with the big tail pipes !

She's getting a proper clean later will take some nice photos !

Yeah I've heard the same thing ! Time will tell ! Can't wait to go back to imi next month and get that extra bit done ! Got a massive drive on Sunday abersoch in north wales to Coventry then bk to the Wirral ! Near 500 miles most of them on fantastic A roads! Plenty of exhaust bedding in miles !
