JHM, TCU and ECU - DK

Subtitles please

Hi Anton

The 4.65 was with stage 1 ECU and TCU tune and with cats. Standard exhaust BUT with rear mufflers removed.

I’ve been hard working this weekend to make a new exhaust system - and I’m no fabricator, so this is literally my first time welding and cutting pipes at angles.

My plan was to have 2x3” pipes from the cats all the way to the back mufflers, with an x-pipe. Right before the rear mufflers there would be an cutout valve.

But nothing would go my way, so I’m on plan E, I guess, and I have front resonators on, then x-pipe, and then straight pipe from there on - all in 2x3”.

On Wednesday I’m at it again to stop the droneage and cut the noise with the valves - right now it’s just straight out a race car (by sound).
Numbers are coming, I just need a break :sweat_smile:

I didn’t get a picture of the x-pipe but here’s one of the other half of the exhaust I did this alone as a first timer so go light on me.

Mac here. I’m interested it the cat deletes. Where to relocate the downstream 02 sensor s at? I left my “ups” where there Were. And put 90s for downsides 4-5 & 9-10 O2s
The 1-3 & 6-8 O2s relocated. I’ll show ya.


Wanted the Audi rings for my center exhaust…once I get my tig
