Emily, please go and do some study.
You didn't like it when I told you to get educated?

Why do the same to another?

She's still studying or should be.
Sling the mud at the ones that have slung it at you. Dont complain about mud being throw at you, then throw it at someone else.

But speaking of studing. I know you need a refresher on fluid dynamics, so here you go:-

Read up. I know you have the free time on your hands.

Another wow from me.
Can't wait to read the review of this awesome product. Am expecting it to be completely original and not plagiarised from the seller.
Actually, I'm surprised dan is still in business having to compete with this product and all...

I tried contacting the sellers and the company website. No responses, even after repeated reminders and expressions to buy. Quality sellers and company for sure!

The welding looks very average to me. The whole thing looks like a nightmare. If it's too cheap then that's what it will be. If it does not fit bad luck. Detergent meths vodka Yeah that will make the difference.

US Headers & Exhausts NA

Postby gslender » Sat Aug 23, 2014 3:09 pm

I don't know, I think after enough Vodka I could be convinced it's worth putting on the car.... Maybe just for laughs, you know, just like how slammin looks cool and stuff. Stupid in terms of what it does to performance and handling, but some folks think it looks wicked. I just see stupid.

external diameter appears to change between welds? or is that just the photo/my eyes?

Agreed. Looks like a dog's breakfast, those unequal length runners.

If this is "tuned", it is done badly. I can't think of a good reason to deviate from what is tried and tested design for equal lengths.

For example, Xforce 4-2-1 design below showing how curls are used to achieve equal lengths.

Pretty much the same.



So they aren't tuned then?

Dupain wrote:So you would expect the primary on cyl one to have a slightly smaller internal diameter to tune it to compensate for thevextra length.




I mean, I could see they weren't tuned right from page 1 of the thread, but even by your own unusual definition of tuned they aren't...

That's a very nice set of extractors....if the work half as well as they look they'd be brilliant

Hard to tell in the photo but the welds looks pretty average particularly the first weld after the flange one cyc 2.

Seems excessively curly given short the primary is still.
