i have a regular high flow cat on my car because i hate the smell of the testpipe. but now that there are these race high flow cats i would like to upgrade for power.

ex:

i was wondering if these still smell?

thanks,

albert

 

i dont smell nuthin

 

no they do not smell. but they DO smell during 'breakin' , kinda like rotten eggs.

 

what would be the power difference between a test pipe and a high flow cat like that one?

like 5whp-ish

 

Are all highflow cats created equaly? or should I avoid a particular Brand?
Im interested in the new Cobb TBE.

Thanks Richard

 

whats the difference between regular high flow and "race" high flow?

who makes race high flow cats?

 

I have the Perrin HFC pictured above.....no smell at all. Good choice for a HFC.

 

Randomtech high flow cat. The EVO model is rated at 607cfm...





they dont smell at all!

 

my ultimate racing 3 inch high flow cat doesnt smell

 

Everytime time I push my car REAL HARD I get the rotten egg smell.

 

which high flow cat do you have?

im trying to decide between randomtech and perrin

 

cant go wrong with either. 2 of the best on the market

 

im not a fan of a high flow cat unless you have a qtp style downpipe.

 

My Sard HFC doesn't smell either....
