moin möchte möchte möchte… so, I have some interest in a new kat. but first of all something else. have recently bought relatively cheap a bastuck and lay full 4 hours under the car to get the old shitty thing off. long talk… had to bend two bolts from the katflansch and drill new holes, because corrosion caused even nothing more. wanted to take off the puff ab hosenrohr in the meantime, but the probes also did not want to off. the plugs either. (it was late, I was in a hurry and was unideally lying under the car in the corner, metal shavings and rust looseners.) laber laber rhabarber, catback is on, but if I want to take the kat in the attack, must the sounds off. does that still be better if the system is warm? has someone experience? but my real concern: at ajr there is the hjs universal (90 is the gitsch 93) and the hich hunden?
