You "cant"? Several Aston tuners have said that the gains from aftermarket exhaust is minimal -- single digit gains. More significant gains are only possible if you change the cats and/or the exhaust manifolds.

 

OK. I was not expecting more then 10hp but surely 5-8 hp.

 

Yes, a gain of only 3.5 bhp is insignificant, but a gain of 5 bhp, now that's a different story.

 

[quote=007 Vantage;3164737]That information is highly inaccurate. There are tons of ways to get a lot more power than that and I will provide the dynos in due time . The 4.3 was sandbagged to the extreme so naturally you can unlock alot more power than that.

And your knowledge base for the above statement comes from what? We have been over this time and time again. If you choose to believe that the engine designer from AM does not know what you know, that is your business. There is just not a way to dispute what Mike has done over there, and what he will soon be doing over here.

Idiocy should not be shared.............
