Hey guys,
Yes another exhaust question.. Search can't really give me an answer to my specific situation.
Anyway, I'm currently running an axle back twin loop (2.5" inlet). While its got the right tone, it's probably not as 'smooth' as it could be with a complete system. I'd also like it a little bit louder, plus the increase in responsiveness that the headers produce would be nice
So, I was thinking of getting some headers & everything else inbetween to make a complete setup. Question is, would the differing sizes work well together?
Example:
Headers (2") > Cat (2.25") > Back Pipe (2.25") > Twin Loop (2.5")
Would that be allowing the exhaust gasses to flow too freely? Not enough back pressure? (Please no arguments about whether back pressure is a myth or not - the theory makes sense to me). Or should I stick with 2" throughout til the twin loop?
Oh, an it's an EK1, so running a D16Y4 with no plans for swaps or turbo. (If I happen to make plans for either of those, it would be because I landed a ton of cash and therefore have the cash to upgrade the exhaust again to suit
Cheers for any input
