Could someone tell me why upgrading the exhaust by installing 2.25"+ downtubes and exhaust pipes on these cars without porting the exhaust manifolds helps? Getting better (less restrictive) mufflers and resonators makes good sense, but I measured my exhaust collector and it appeares to be right at 1.75". This being the case, it seems that the restriction caused by this is still there even if you do change the d/t's and pipes....Does this make sense?
Thanks,
Mike
Any opinions on X-pipes? Does it change the sound when using aftermarket (Dynomax) resonator?
