Default Test pipes ? Regrets ? Do em? Thanks!

title says it all.. it's almost 2019. I have a completely stock 08 e92 6mt, should I cut off the primary cats and put on test pipes?

I'd love to hear some thoughts down the road, I had an e46 m3 with catless headers, and the sound was nuts in a good way, very f1 but creeping past people with a barrier next to me in the morning commute i felt very silly

Is a primary cat delete similar on the e9x? Any thoughts or recommendations?

The car is stock BESIDES the "acm" mod muffler bybass. This gives it a meaty sound already, zero rasp. But still a little quiet. Would test pipes plus this, be too much for a street car? Also what's it's like getting an inspection sticker with no cats ?

If you want better sound you have it with the rear exhaust. If you want more power, do test pipes and a tube or even better a resonated x-pipe and tune so you can swap your stock pipe back if needed. Add pulley and intake and the power will be noticeably better than stock.

Software and Test Pipes is the best performance upgrade for the S65. So if you are looking for a good bump in power and a little bit of a sound upgrade this is a great setup.

If you are just looking for more sound I would look at changing the muffler out. The muffler bypass is nice but a muffler that is designed for the car will sound much better, or at least I think so.

We are big fans of the Corsa Sport Exhaust system, or Borla ATAK system paired with our software and test pipes.

If you have more questions, please feel free to email me directly. Seank@turnermotorsport.com
