Cats and Hotdogs :)

[nvs_sle]

Hey guys, i got a fairly stock 3.0 with CAI extractors n a 2.5" exhaust with the stock mufflers, im thinking of changing the rear with a hotdog or there abouts, and i also have a new hiflo cat at home, if i were to put the cat and hotdog on at the same time, would i have issues with lost back pressure? or should i be right.
cause im also getting abou a 68 or 70mm throttle body soon which will mean more flow.
cheers

The rear 'muffler' is not a muffler. it's a resonator. you don't need to have it by law. i have mine though just to stop the 'drone' of the exhaust while doing highway runs. it also helps to keep a bit of back pressure. i'd change the muffler to a straight through muffler cos the stock ones stagger in the flow, ie the in and out of the muffler is not inline. Is the exhaust mandrel bent?

 

[nvs_sle]

yeah all the pipes are mandrel bent, im considering either taking off the rear resonator completely or having a hotdog there to give it a bit of sound and reduce some drone aswell... does anyone know roughly how much a hotdog resonator is? aswell as another straight through muffler to replace the centre one?

I wouldn't worry about putting the hiflow cat on.. I hate the things.

yeah im not gunna put it on, just change the rear resonator and have a nice 2.5" dump tip, i reckon they look top shelf!
