Quietest turbo back for stage 2

(1/3) > >>

ksamyui:
Looking to go stage 2 but not interested in any extra noise other than what’s necessary to free up flow. What’s the best turbo back option?

breeze:
Good question.

I’d guess:
Sports cat and factory catback to be quietest, then something like a resonated Milltek catback. Resonated Milltek is very quiet. BCS Prestige gets good reviews, not clear if it would be as quiet as the Milltek.

Is it a K03 or K04 car and what are your power and torque goals?

Thanks for that, it’s a Ko3; I don’t have any specific goals on power and torque, but now you’ve got me thinking :-D. I’ve always held that the power of my e46 M3 was just about perfect for UK roads, although could have done with a little more torque. That from memory was around 340bhp and 360nm torque.

Obvs I know this isn’t an M3, so somewhere around 270bhp, 290torque?

When I bought the car a few weeks ago, I was toying between something heavily modified (tried a couple of ed30 highly tuned, the power delivery was quite incredible ) or something strong and standard to mod a little. I opted for the more standard, only because the modded ones, in my price range, were all super high mileage, dubious history or category damaged.

If you want torque, then you’ll be needing an upgraded hpfp more than a cat back. Vis are a popular option. For quiet, sports cat downpipe / stock catback / stock airbox / vis hpfp / s3 intercooler will give you around 270bhp / 320lb ft.

Another approach would be to convert to K04 / K03 hybrid but keep it at stage one. Quiet and no mot hassles.

Would those figures be ok on a stock clutch?
