X-Force cat-back vs middle muffler delete

[Tawfxr6t]

Hey guys, currently got a FG tuned to around 300rwkw, looking to get a little more sound of it, currently got a venom hi-flow bolt in cat with stock dump/cat-back. Getting a middle muffler delete will run me $200 at a local exhaust shop so I was thinking it might be worth just going for a cat-back system. Looking at X-forces range of cat-back systems I got quite lost at which cat-back system would be suitable as I'm planning on upgrading to a X-force cat/dump with my next stage of upgrades. Which X-force cat-back system would fit to a Venom bolt in cat and would this system also work with a X-force cat/dump later down the track?

Also I've read that any changes to the exhaust system from behind the cat don't require a re-tune, is this true?

If you buy a cat back that works with factory dump/cat, then as long as you later get a dump/cat that works with factory cat-back (most do) then you'll be fine.

I'd get another quote on the middle muffler delete though - seems pricey.

obviously that's not a delete, it's a replacement hot-dog muffler or something for $200.

 

if you get a cat-back system it'll make plenty of noise (maybe even too much, depending on your tastes).

The quote was 200 to cut out the centre muffler and replace it with a 3" mild steel straight pipe, 250 for stainless.

go to a different exhaust shop as they're ripping you off at that price.

As much as I'd like to agree exhaust shops charge a heap lately, especially with anything not an OEM replacement kinda job.

That's how Sydney has been the last few years anyway, unless you know someone.


Knowing someone cheap and good, good luck lol.

Is a centre muffler delete with a hi-flow cat obnoxiously loud? Ive only heard it on car running stock cat/dump. 

[k31th]

it has a chance to drone at highway speeds.

Rear muffler delete sounds like a droney *beep* middle muffler delete sounds like a droney *beep*.

 

Replace both mufflers with resonators.

 

Sounds sexual.

Just wondering about the stock pipe size. I think it's already 3"? Which should support a decent amount of power. So do you need to replace the actual exhaust piping or can you just replace the middle and rear mufflers?
