Exhaust system diverter

[Storer]

Would it be sacrilege to fit exhaust diverter valves to an Ultima??? (suspect I know the response).

I have a crossover box ATM which is not quiet but the thought of that Le Mans racing Corvette sound is eating away at me.

Work I can do myself, switchable and I will loose the couple of Kgs in weight it will add, promise....

Paul it seems a good idea. but how much noise does it make?
please post a video for noise and photo of the current situation

Not sacrilege at all, if you do it, get the diverter part as a side on exit for full on c6r effect lol

[Racingroj]

Proper idea that Paul especially with Deadscoobs side exit suggestion!

[confusionhunter]

Nope! Makes it a practical road car and can also make it sing like it should. I know a couple of Ultima owners that have essentially removed their silencers and the cars sound glorious! However have neighbours so that isnt an option for me unless I fitted diverter valves.....which I have on my list of things to investigate

Gosh, no negative comments. I'm not the only 'big kid' out there....

Getting a side outlet will be a challenge due to the fuel tanks and other stuff in the side pods.
Maybe behind the rear wheels, but then issues with the hinging rear clip.

Time will tell.

I have also thought about this, I know my exhaust is a bit restrictive and thought about by-passing the final silencer boxes,
I have reduced the power output of my engine however and so put this idea on the back burner for now.
What diverter valves were you thinking of using?

Paul, you know the answer to this as i have done it.
its bliss.
156db but no one including police give a toss as it sounds fantastic... not that much louder on ticover so dont abuse it in towns to get noticed,,, but the noise,,, omg.. 1980 f1 car scream.. simple x pipe 2 small round silencers..

You could always move so you have no neighbours

PS. I haven't even opened the rear clip yet to see if it is possible. Bit busy on other things!
