V6 Exhaust - Post here

[randomhero365]

i paid 330 fitted for a 2.5 with resi and he quoted me 250 with no resi
i since have had a high flow full size 2.5 (some places neck them down in middle) which cost me 300 fitted
so seen as ur getting it all done at same time should be a bit cheaper
shop around or go ebay for cat back there piece of **** to fit up and get the cat done at exhaust shop

Yeh thanks.
Unfortunately im not that confident in working on my car in that way just at this moment.

has anyone had much experience with catalytic converters?

difference in sound between:
hollowed out v6 cat
5l cat
ls1 cat
high flow cat

 

[padrickz88]

any hollowed out cat sounds like crap.......

im pretty sure v6 and v8 cats are the same

and ls1 cats flow pretty good from factory?
and a highflow, the name is pretty self explanatory

without going into too much, how stock is your car?
As mentioned above the 5lt and v6 cats are the same. A high flow cat really isnt that much better flowing that the stock cat, and on a v6 i doubt that it would be outflowed as it is. My old calais had a highflow cat, it really mde no difference on the road and i think i picked up 5kw on the dyno.

its not power im interested, its sound. its an auto v6.. so im not going for power.. saw a 202 the other day tho that sounded pretty tough running 1 3/8" pacies into a v8 cat, with 2 1/2" pipe and a single centre muffler, no rear resi.

i do know of hollowed twin cats on an ls1 (not going to mention names for legal reasons..) that sounds tough as.

i know the one (no its not me ) yeah one of the better sounding ls1's

 

[bpottz]

so there is no difference between v8 cats and v6 cats? :S

i know hsv have different cats, surely 202's, 308's, ecotecs and ls1's dont all have cats that sound exactly the same

i got a pair of used LS1 cats under mine. Look exactly the same as stock VS V6 cat

looking and being can sometimes be two completely different things tho.
