I bought manzo y-pipe and megan racing resonated test pipes to my 350z de, couldnt even test them when i got my z crashed. Now I got 08 G37 coupe 2wd so im wondering does those parts fit to my infiniti? And i mean like bolt on, not after 10h customizing. I tried to look for old threads from this but couldnt find any help. If those wont fit bolt on, can they be modded to fit with small work ( making bit shorter example), if so what should be customized and how?
​​​​​I wouldnt want to buy new parts cause I live in Finland and I have to pay ridiculous amount of taxes on every part (we pay like double on everything that people pay in US on these parts). All help is needed, thanks already✌️

 

The Y pipe will fit no problem.
The test pipes wont bolt up as is because the top triangle flanges are different. You could cutoff your stock cat flange and weld to test pipe and they'll fit or buy aftermarket DE headers they will bolt up to the g37 heads nonissue and then use the De test pipes on the headers.
3rd optIon is cutoff de top flange and header flange and weld them together directly.

 

Thanks, this was big help! Do you know does aftermarket DE heads flow better than the stock g37 heads or is just waste of money? Gains isnt what im mainly looking, just want better sounds but still dont want to lose any power

 

waste unless you're going to go fi
