No fitment issues at first, between the downpipe and the rest of the cobra system.
However after a few years ( i owned mine 5 years before moving on ) i did notice that where the downpipe joined the cobra system, it wasnt as smooth as my OCDness would have liked LOL hence exhaust gases were blowing only very slightly.
When i do it all again ( watch this space
) i will purchase a full cobra system, using there downpipe.
I have completed a search around and scoobyparts is the cheapest for the 3" inch SB32d system priced @ £639, get a 5% code, sees that lower to £607 for a brand new full 3" system is pretty good value tbh.
