I just got my licence back and at the same time got extractors and 2.5 exhaust on my XE. Sounds great , very loud and improved perfromance.
However when i cruize in any gear it stutters a bit and when i change down a gear with highish revs it pots and bangs like a really loud milo tin exhaust on a ricer. Is this normal. The muffler was of a v8 if it makes any diffrence?
Are the two problems related? I just did the plugs, oil and and filters.
It ran fine before the extractors and exhaust. Is the setup too big for the engine?
Its only illegal if you get caught!!!
