Fitted 63mm freeflow exhaust...

[vetonix]

Two days ago a fitted a custom 63mm stainless steel freeflow exhaust and got the cat removed, straight pipe with 2 boxes.

I haven't had the car on the dyno yet, but it's very difficult for me to tell if there is any increase in performance, the car actually feels a bit slower...

The noise on the other hand is crazy, it's got this loud drone when just cruizing at normal speeds? Is 63mm the right size for my car? Is that equivalent to what seems to be the 2.5" standard on this forum?

Any recommendations as to how I can get get rid of that annoying loud drone, I can hardly hear myself think!? :dapprove:

probably needs a remap to get the most out of it

doubt you will ever get rid of the drone. a few people on here used to have Supersprint systems (63.5mm) and they got rid because the noise was hard to live with daily.

i went for a stealth system and janspeed decat. doesn't drone but you get a nice rasp top end.

what system is it? sounds like a crap design.

our BTB system is 63mm bore, and isnt too loud! as it was designed to be track day friendly!

IMO, I'd get it remapped & on the rollers it to make sure its running right..

i ve just fitted 63 mm magnex.thats awesome.you need remap and quality backbox.custom backboxes loose backpressure

i know from a performance point of view it wont help, but putting the cat back on would help with getting rid of the loud drone the new system is making? or maybe even a 3rd box in the middle, where the cat use to be? what you guys think?
