Get him to just tack weld it in place and then turn over the engine. That way at least you will get an idea of what it will sound like.

The longer the resonator the softer quieter the final sound, so it is up to you about length.

oh ok, well that buzz sound is only happening under acceleration, idle sound is beautiful deep note/down shifting is a beautiful note.

imo get the same size as your oem resonator. im surprised he didnt re use it?

man im never goin to this shop again, i should of just sold u a complete catback

i suck

oi trav dont be hard on yourself, there isnt anythign wrong with the muffler, if anything it sounds like it is the XF cat..
so i'll put a resi on it and if that doesnt solve anything i'll change the cat to a 2 1/4...
(apparently the downgrade to 2 1/4 cat helped out an OH member on the noise)

**Micko** · 17-01-2007 11:05 AM

i just think the noise is because from my extracotrs the collector was cut off and a fexi pipe was installed at 2.25' and piping all the way then flanged at the 2.5' cat - from there the piping from the cat is 2.5' all the way to the twinloop with no resi installed. once again a setup i never asked for...
i think by installing a a resi will help but not alot, i should just rebuild my exhaust down to 2.25 from the cat back....

Yeah - Trav sucks

. Just kidding

I wouldnt have thought using the oem one would be best as the inlet/outlet size could be to small. As I said earlier, get him to just tack one into place and get someone to rev the engine. Sit in the car and stand behind the car and make sure you are happy with the sound before they build it. If you were in Victoria I would recommend you a place, but goodluck with it all.

ok i got it back into the shop, got a 18" resi on it, killed some buzz but not all of it, the buzzing is actually comming out of my twinloop muffler, how unlucky

*i know i said it wasnt the muffler until they got it up on the lift and showed me

perhaps the buzzing sound will go away after the zorst has been used a bit more. you can only hope mate.
