NK Rally Road Vs Franspeed Race/Supertourer

[servetakid]

Does anyone have any dyno graph comparisons between the three exhausts, or at least some graphs on similar spec'd engines.

Cheers

As an aside I have had all 3 on my RB. The NK road was more grunty down below but I lost power band in all gears. The race is quality and whilst being revvy it still okay about town. the super tourer was a good pipe with a good spread still had the power band in all gears as per the race but was smoother at lower revs and speed than the race. Saying all that I still opted for the race in the end.

Probably doesn't help you though

Hi Ive used the race and super tourer and find that the race is a good pipe and will rev out to 9000rpm and will pull good from low down the super tourer gives a nice spread of power through out the rev range and will rev up to 8200 at least you may lose a few hp over the race but I find the tourer a better pipe for round town it all depends on your tune and what you want out of your engine good luck m8

The race will rev higher than 9k on the right motor.

The dyno plots would be fairly meaningless unless you've got the same engine spec.

i have the graphs for all the pipes on various engine set ups but then developed the kits to find the best durations that suit them ,theres quite a change to how they behave on lets say a rapido classic compared to a ts1 or an rb20 a racy pipe can be a docile pipe if the set up suits
