So I recently did the UK mod to my exhaust and I can hear the difference, but I want a little more OMPH! Should I do a HFC or a test pipe. If you guys have an sound videos or feed back that would be great!

 

Did you remove the resonator too ? I heard it will get a little louder with the UK mod .

 

I added a 63.5mm Berk test pipe to my car and it is quite a bit louder than my friend's who has a Berk HFC with UK mod. In my opinion, it sounds great, not too loud, and a good tone. I'll add in my sound video as soon as it uploads.

Edit: Here you go. My UK mod is a 44mm btw. https://youtu.be/5vMyQtle9yg

 

^^Sounds good!!, makes me wanna do the UK exhaust mod. And I allready have the berk 63.5. Wonder if anyone supercharged has done this?

 

man that sounds sick. I've made my decision. Lol.

 

It does sound great with the test pipe but the smell is awful with the roof down coming to a stop. Mine was on and off in two days after the lady was complaining.

 

That does sound good. Im intent on keeping stock exhaust due to the peace of mind while "spirited" driving. Is it still quieter than an hks hi power?

 

much quieter than any exhaust. You will only hear it once you get on it. It's perfect. I'm just looking for a tad more of a grunt.

 

what smell are you talking about?

 

I don't remember the specific names of the gases eliminated from the use of a CAT, but when you take out the CAT and replace with it a straight pipe you are no longer converting the noxious gases. As a result the emissions produced stink and pollute the air. Some people don't mind it, but there's no way I am submitting her to the smell if she doesn't like it.

I'd try and find a local and ride with them with the roof down in stop and go local traffic.
