Hi all,
Happy New Year,
I recently had a scorpion stainless exhaust system removed from my MK5 XR3i 1.8 ..16 valve..It was a bit too noisy for my liking and had a 4 inch tail pipe. Got my local guy to source a standard exhaust..Took him three weeks on a back order.. But now since I had it fitted my engine doesn't rev out crisply once warmed up.. As the XR3i was also made as a 1.6 CVH 8 valve I'm wondering if its possible my guy put the wrong exhaust on my car. My question is ...If the bore was too narrow on the new exhaust and it does look narrow...Would this cause my engine to not rev out properly.?
Or is it a coincidence..The issue didn't seem to be there with the scorpion..
Thanks all,
Morg.
