Hello,

sorry for my english.

I have a WRX 2003 stock, with original downpipe.
I want to buy a Cobra catback.
I need advice for choose with or without resonator.
I want something loud, but not too much for not have problems with police and neightboors ^^
i'm affraid by the resonator, if it's not loud...

can you give me advice please ?

thanks

 

I have the Cobra trackday system fitted here - https://cobrasport.com/products/suba...32120062476369

It's plenty loud enough without being too in your face

 

Ok thanks.
I want the race version.
Have you eared the race version already ?

 

Which one is the race version?

With or without resonator

 

That it is a stright through system, so i would imagine it will be pretty loud, although it is only a 2.5" system as opposed to a 3".

 

I had a different back box with an unresonated centerpipe and replaced the centerpipe with a resonated cobra one. It made it less raspy, little deeper and a little quieter with less drone. Still loud enough, so I think you'd be ok with resonated. If you really want loud and aggressive skip the resonator. It won't be a day and night difference either way. Hope this helps!

 

Agree - the resonantor made a huge difference for me in the actual sound of the exhaust, sounds nice and deep now.
Prefer it so much more than my old Miltek system which struggled to pass many track noise limits.

 

thank you
