Comp pack exhaust vs stock

jbomb · 05-30-2014, 10:00 AM

What is the exact difference between the two.
Is it simply that the comp pack has the baffles removed and replaced with a solid Y pipe?

I thought they're exactly the same exhausts except the tip colors (chrome vs. black pearl).

I'm not 100% sure.

Here is an extract from the specs on the comp exhaust -

It's sportier sounding than the stock exhaust by having its baffles pulled from the muffler. No power gains and no flow change.

I didn't know that- I wanna find out this as well... Anyone?

It is louder and it has some of the baffling removed. I am not sure about the solid Y pipes, but I don't think that is the case.

///SAL · 05-30-2014, 08:57 PM

Sound is confirmed and also their black polish tips too

jbomb · 05-31-2014, 04:19 AM

Has anyone got a pic of the comp pack cracked open?

I have a spare exhaust so I'm keen to replicate the comp exhaust setup.

I'm not sure whether to remove the baffles and not add anything at all, remove baffles and add a Y pipe or finally fill in half the holes on the baffles?

So you can remove baffles?
What a out valves?
I thought they were open in CP and closed in non CP and that's it but this thread says also no baffles?
I am baffled by that -

TZL · 06-01-2014, 07:03 PM

The CP is maybe 25% louder at idle

My next door neighbor has a non-CP and his car is significantly quieter at idle

Not sure about at speed

jbomb · 06-02-2014, 05:15 AM

I just can't work out the exact difference between the two.

corrado79 · 12-08-2014, 02:21 AM

Bump for a good, but unanswered question.

JPMD · 12-08-2014, 06:28 PM

I believe baffles removed and also it's been confirmed prior posts that the resonators have been deleted. (This saved me a few bucks and a little embarrassment as I was scheduled to have a muffler shot cut the pieces that looked as if they housed them)

Do not believe the flaps are any different or programmed differently as I have a comp pkg F10-M5; added exhaustmeister.

CP pack doesnt have resonator

Non CP have resonator.

Only difference is a different bafflle confirguration or partially removed baffling and the black tips.

I've seen both up close in person.

Non CP
