Hey Guys! I have 2 problems

1.) This problem already had been occurring before installing the new exhaust setup: the car stalls when shifting around 10-15 mph, 1200-2100 rpm range, If anyone could help me in that it would be great.
2.) After deleting the secondary cats and resonator, seems like my car lost some power I can feel a difference indeed. Install setups; have a "y" outlet - the muffler shop guy suggested 😩 from the old secondary fitment and have. Straight pipe from there, and resonator deleted to the muffler.

please let me know, what I can do; or steps I can take: also it's my first post 😬
Cheers

Is this for your C55? I have that exhaust set up on my C55 and I'm positive I haven't lost any power. Can't help on the shifting issue.

Did you let the oil warm up? Does this just happen on cold starts?

Yes its for my c55, it seems like the acceleration has lost I know when I did it for my e46 bmw that happened as well - car sounds great! But when I push the gas it seems like there is a drag or lag. No lag because its naturally aspirated but it seems like it - let me know thanks

hey yea! If its warm or cold, it does the same thing sometimes it's bad, sometimes it's okay - just don't know what's going on?? If I gas it down all the way... u can't tell that much, but if u want a smooth transition in gear shifting at low Rpms it jerks
