Hello,

How much would be the sound increase with a stock muffler if I change invididually the a)second catalytic converter (the one in the midpipe) for a high flow metal substrate one or b)stock resonator for a Vibrant "hotdog" resonator, or even the two items combined?
Which one of those would give the best sound increase if any?Hope to hear from you guys soon. Thanks in advance.

 

all would increase sound level.

i suggest high flow cat. and a new muffler. flowmaster...hks what ever your after.

Thanks for your reply and the video sample Zsanz.

 

no problem

 

Then again, is there a big difference between the stock resonator and a "hotdog", and between a hi-flow cat and the stock one?

 

Changing anything will increase sound. If your trying to reduce sound as much as possible then go with the Vibrant ultra-quiet.

My set up(in my quote thingy below) was HORRIBLY loud. But i welded in a vibrant ultra-quiet and it was like night and day. Sounds mean too.
