Want car loud . High flow cat install?

Can you tell any performance increase with this setup

They say you're suppose to get a few added HP but not enough to be able to tell the difference IMO, unless you got WOT in which I haven't yet! I did this solely to get that extra 40-50% added growl and didn't want to sell my MAK race pipes considering when you're buying stuff from the US to Canada nothing is cheap so this whole setup started at $1134CAD including 2 X welding fees because I went back to my Borla setup and went back the third time with these Thunderbolt HFC's to have added to my MAK race pipes and cost me another $500+ including the 2 X Thunderbolt's and welding costs, that's $1634CAD for this setup...

I'm thinking I just might get 400 or 300 cell catalytic converters and replace my stock cats my h pipe and sve axle back sound good I just want a little more noise

Go with the 400CEL because then you'll pass EPA emissions testing in all states except for CA & NY and the bonus is you won't be smelling any fumes when you go 400CEL! These Thunderbolt's 99659HM are made 100% identical as the Magnaflow 99659HM which is around $300 per/cat and the Thunderbolts are half that price!

Here is a clip the the Borla S-Type Axel back with SR X pipe, MAK race pipes with 3 inch Thunderbolt 400CEL High Flow Cats. Wished I had a Go Pro to show the true tone but my Samsung will have to do!
