100% no issues.
I have a high flow, a custom dump pipe, had a Kakimoto 80mm de-cat front pipe and a Legalis cat-back.
No issues whatsoever.
Indeed... whether it is the engine, transmission, DVD "player", suspension or exhaust, there are very, very few sellers and workshops that get their shit right with these cars.
Hmm... maybe someone needs to put a website together where people could easily get the right info on these cars....
