Guys,

To help to reduce the overall sound loudness my exhaust (DP + Megan) but more specifically the cold start and cruising speed sound I plan to install bottle style Vibrant resonator in the mid section.

I need your help for the sizing.

Do you know if our 535I mid section is 2.25 or 2.5 piping?
Also do you believe 18 long resonators could fit in the straight section or if I should go with 12".
Lastly there are 4" round and 5" round. Can two 5" round fit side by side in the mid section?

Thanks for your insight.

I believe it's 2.5" if you are still unsure use a caliper ruler. 12" bottle vibrant resonators will do the trick! Good luck dude!

I went ahead and purchased two 12" 2.5 inlet /outlet resonator from Amazon but they seems to be B/O so will get them in September.

I hope they will clean a bit the exhaust sound.

Should have bought them on ebay. Cheapest I've seen is 48-49 shipped.

In fact I bought them from Amazon.ca since I am from Canada and paid 120 $CAD for both which is around 90$USD these days! Very cheap if it indeep improve the sound quality of my setup.

I believe Vibrant is a Canadian company so that is why this time (not often) it was better to buy from here.

Thanks anyway.
