Theres no rasp.. You hear the hissing through the exhaust because of all the flow.. But theres no rasp at all out the back through the mufflers just music.. unless ofcourse he has no resonators...

I happen to like the sound of both. I want it to sound like a race car, not a Lincoln Continental

Ok it's a done deal. My car is at the stealership getting the swap done. Also keep in mind tht when you guys install these be mindfull of the steering linkage position. There was about a centimeter of play in the steering wheel that i noticed on the way there.

My Fast Long Tube Headers are up for sale as soon as everything is done PM me if you are interested.

Good talking with you today. I understand and agree as to why you shouldn't put these back on your car. You do not need to give the Southern California law enforcement any more ammunition against you. After all, you already own a red sports car. That in itself is like having 2 strikes!

Thanks, Tony

Jordo!

Looking forward to dyno results -- no baseline????

Just to be clear, LTH's will possibly have some low end losses and make most of the gains up top...

EDIT: No, no -- other way round -- duh...

Incorrect, these LTH have gains on the bottom and throughout the powerband and a minor loss up top.

Duh, yes of course that makes sense -- long runners move peak torque downwards in RPM range (short runners generlaly mean more power up top) -- I don't know what I was thinking when I wrote that ... had it backwards (have another beer, Jordo)

Thats still not entirely correct.. the long tubes increased torque for the Z accross the entire rpm range vs any of the shorties available for the z. And power has increased over the entire rpm range it depends on the exhaust your running.

Thats the general rule of thumb as far as relative runner length for any combustion engine (which I wrote totally ***-backwards)... you can develop a stepped design that will widen the powerband, which may be the case here, but if the power gains move in the opposite direction then VVEL tuning is likely to blame.

In general, longer runners = peak torque moves down; shorter runners = peak torque moves up. Pipe diameter will fix total possible peak power.

Individual results may vary

Improved flow should (overall) move peak torque upwards too as you tend to see peak cylinder filling (and therefore empyting) at higher RPM's, depending on head design and displacement, that is...
