Help, please! My IS250 (2006) has a terrible droning noise coming from the exhaust system at between 2,000 and 3,000RPM.
Last week I purchased a 2006 IS250 🙂
Coming from an 08 Mercedez C320 I have been very impressed and feel like I should have made the jump to Lexus much sooner!
The only issue is an awful droning from the exhaust system between 2,000 and 3,000RPM.
I took a look and can see the exhaust system has been replaced with an aftermarket unit. The exhaust tips and muffler unit are branded 'PowerFlow'.
Is this an issue with all stainless steel replacement exhaust units or can anyone recommend a solution?
Any ideas anyone?
