Been playing with my exhaust
Discussion
Hi everyone,
Up until yesterday my Monaro VXR 6.0 had a Milltek exhaust which was 2 completely seperate pipes running from each cat with 1 rear silencer on each, nothing in the centre. See below:
This has always made the car fairly loud and have a very burbly muscle car sound, which has been great. However I fancied a change and did not want to spend a fortune so yesterday I had an X pipe welded in which I have no pictures because the garage put the car on the floor before I could have a look.
This has had some interesting results.
The power delivery is very different now! I guess it feels like the car has a little less low down torque now but is a lot quicker to rev, and there is definitely more grunt towards the top of the rev range then before.
The noise has changed somewhat, I supose it is now les burbly and more raspy, reminds me of a V8 M3 and a bit like my dads SL55, less old school I suppose. Still sounds great just different.
The only downside is it actually seems to have made the car a little quieter, which was not my plan. It's a different noise but slightly less of it, I want more! I am thinking about going mad and just deleting the 2 rear boxes and going straight through, have some fun with it for a while.
Has anyone else had a similar set up? I am just curious as to how loud it will be, and if it will sound good or just be lots of horrible noise. Will it affect the performance atall?
I had cutouts fitted a while ago these were rediculously loud but the noise was not pleasant, so I got rid of them.
I guess this is because the cutout is essentially a big hole halfway though the exhaust, this also made my car very slow so I just had the orignal bit of pipe welded back in. This is where the x pipe now sits.
In an ideal world I would rip it all out and start again, but I cannot justify £2-3k on it at the moment when I already have high flow cats and a decent system to start with.
Anyway any comments on the changes I have noticed and if straight pipes with an X has been done before and how it will further change things will be great.
Thanks
Karl

Thank you for all the answers so far. The car is purely for fun and as I do not drive it very far really loud is great, adds to the occasion. However I would like a nice noise, the problem I found with cutouts was it was not a very nice noise, just sounded like an exhaust blowing.
And the main thing that puts me off is that the performance of the car was affected so much, that is what I want to avoid.
I cannot see why straight pipes would effect performance atall but then I thought this about the cutouts!
Would straight pipes be as loud as open cutouts? I would expect not quite but hopefully one of you knows for sure?

Well I guess there is only one way to find out, I can always put a different rear box on afterwards if straight pipes are not to my liking.
My cutouts were fitted a foot or so in front of the rear diff as you might be able to see in the picture.
It does not sound like straight pipes have affected anyone elses performance before?
