Changing Exhaust

[1986 930]

So I put a B&B exhaust on the little beast a year ago when I upgraded to the K-27 HFS and B&B Headers and I have to say it has a very anoying harmonic at 80mph. More anoying than a 7 year old asking if we are there yet every 5 minutes on a long drive! Given that, I am thinking about going back to my 4 pipe RUF Exhaust I took off of it. Not quite the throughput but a little sweeter, less angry sound.

So my question is will changing the exhaust require tuning the fuel injection again. I kind of figured that it wouldn't but it never hurts to ask.

Thanks,

Mark

Probably not. At most you may need to tweak the mixture screw. Only your AFR meter knows for sure.

Agree. The RUF is a great exhaust.
