Hi all,

Looking to get a company to weld my 340i backbox onto my 435d (because I hate the 2 exhaust to the left look for the 435d).

I was looking at going with Style Dynamics (in Hayes, London), and they're charging £150.

According to another member on here, PowerFlow Exhaust (in Leicester) charge £80 for to cut the original exhaust and weld this 340i backbox on to my car. I called them and they confirmed that it is indeed £80.

That's a big difference in price, however, the quality of the work and the weld is what matters to me the most.

Anyone have any experience with PowerFlow Exhausts Leicester? Also known as Mr Tyre Leicester.

Alternatively, does anyone know any amazing exhaust welding shops, that can put a 340i backbox onto a 435d?

Would rather pay more for an amazing job, instead of paying less for a shitty job and stressing out.

TIA.

It was me that shared on here that Powerflow do it for £80

I went to their garage last Saturday and they have an impressive setup! Defo know what they are doing.

UKF30 had his 420d fitted with the same backbox at the same place. I'm sure he'll be happy to send/share his pics with you. The quality of work done on his car was really good (even if it is just welding).

Darth Helmut had his car done at a different place and the job was quite a pain they said to get the pipes aligned perfectly. He had carbon tips though so that may have been harder as they need to be a certain way up.

Either way the garage said never again would they do the job

This chap in Loughborough did my dual exhaust conversion on a 335D F31 and I am very happy with the work he did - £120
