sorry about reviving an old post but was wondering if anyone has 'drone' in a mod'd or std sportwagon. mine is still std but i notice a drone like noise in 4th between 1600 - 1800rpm. was thinking this will be exaggerated once i put a cat back on. any one else notice this sound?
Hi Mondo,
I am told that some systems will not drone on a wagon. I have a Series II SS Sportwagon with the following;
Walkinshaw headers
Walkinshaw high flow cats
Walkinshaw exhaust 2.5" exhaust pipes until the mufflers
Difilippo mufflers
ORSSM OTR intake
Dyno tune
Ok just to explain the lessons I have learnt
1. I don't think you can ever fully eliminate drone in a wagon. The cabin space is larger and exacerbates drone.
2. With Walkinshaw you pay for the name. The gear in not necessarily better. Be careful which Walkinshaw places you go to! The one I went to was rubbish and the bloke was full of crap. I have the wear marks on my steering column to prove it!
3. If you want a meaty sounding wagon you have to live with drone.
4. If I had my time over again I would have let Murat from Marranos in Croydon, Sydney look after my car from the beginning this guys customer service is second to none! My daily drive goes there as well and is looked after really well!
My car drones at around 1,700 RPM but not much before or after. Difilippo exhausts are expensive but the best in my opinion. You get what you pay for in this case. If I had my time again in would be a Difilippo system all the way through.
If you need any other advice mate then I am happy to explain my experiences. I am no mechanic but I have learnt a few things through shelling out hard earned cash on fairy tails.
Cheers
Benny
