Just listen to the Hondata dyno vid, and the Toda sounds similar to that.
Haha, I know but it was really a cash flow issue. Have to save for each item one at a time, can't afford to splash $10k straight after buying the car.Quote:

Metal cat is good. You need to bring it to the exhaust shop to weld on some flanges though as it doesn't come with them for the Euro. Also, you need it done up in the right length for the headers.Quote:

I reckon, in term of gains shouldn't be much different probably the difference is the built quality and material.Quote:

The only dyno I've seen was the works including cams, valves, springs, retainers, intake manifold, exhaust and cat as well as the headers.Quote:

I guess the Hytech exhaust combo should be the most extreme exhaust for CL9/CL7 atm. The header is longer tube design which tend to be racing header and works even better with aggresive cams. I want them myself if only I haven't got full exhaust system atm. :DQuote:

Anyway the DC sports and comptech doesn't come with test pipe or stock cat elimination compare to toda which could cause higher output.
It'd be hard to know the difference without side by side dyno testing, on the same car, on the same day. Both are well made and designed to perform. I've been happy with the maxim works but Toda is cheaper and if the gains are at least on par it's probably a more economical choice.Quote:

That shows that ,when he switched to 45 vtc, produces higher mid range power and torque which is around the same with hondata dyno graph you showed so clearly it wasn't from the header.
How would you go about shoe-horning a hytech header into a euro?
I don't see it fitting without clearance issues. Has anyone tried it?
