Hi guys just wondering about Our R's. I did a search and found nothing I wanted, here's the question.

If i use a test pipe(just out of curiosity) if and when my CEL comes on, will my car go into limp mode or decrease performance?.

Sorry Mafay2, I had to ask for other opinions, I got too much mixed answers!

 

no limp mode.

 

thank you, now will it decrease perfomance

 

no decrease at all... it pulled better over 7,500... all the way up to redline.

just be ready to clean your rear bumber off.... and enjoy the smell.
