Default Spec C exhaust recommendations

Hey,

Sorry if this questions been asked before but I can't seem to find anything. I've got a hawkeye Spec C and with the twinscroll the exhaust isn't quite as loud as I'd want. Can anyone recommend some exhausts that sound good with the Spec C setup? When I get a new system I'm going to look to get it remapped to V power as well.

Thanks

Miltek, nice noise when driving properly and when on boost also thats what litchfiled puts on the T20/25's.

i have a hawk spec c and have a full 3' system which is seriously quiet...until it comes on boost and it is loud.

I agree with the miltek, nice and quiet but sounds great when you boot it. Should also pass noise regs should you decide to track it.

As far as im aware, cobra dont do twin scroll decats (or they didnt the last time I asked, not enough of them to go around) so for full exhaust recommendations you only really have 2.

Hayward and Scott, undoubtedly the best quality and great sounding

Milltek, nice sound but has been known for some really dodgy quality considering the price (bad welds, rust etc), which is one of the reasons I went for a H&S.

I can vouch for the Nur Spec on a twin scroll! Have one on mine, coupled with a 3" decat straight through to the backbox. It sounds like satan himself howling when on full chat

Hi any vids on blitz nur on a twinscroll I hate the milltek on mine had a blitz on my sti-prodrive turbo back what an animal wish there was a way to put unequal length headers on a twinscroll instead of changing turbo and manifold as well, or is there a way of changing headers without messing with the turbo

Why?
The twin scrolls are far better and sound nicer tbh, they have the proper rally car sound because the rally cars use equal length headers, just like the twin scrolls
Having owned one of the first twin scroll cars in the country back in 2004, I can say that I prefer the sound of them to the "burble", they do actually burble slightly if you listen carefully but have a much nicer roar when giving it some beans
