Just upgraded my Griff to a far newer one

Asked the dealer in a moment of louditis to remove the baffles on the back box (ooeeerr missus)after he confirmed it wouldn't knacker the performance. What I failed to ask is exactly how loud will it get. Has anyone done this and will I need earplugs for the drive home.

Being a generally noisey git anyway I'm looking forward to the extra racket. I guess if I'm going to get frowned upon by the neighbours for daring to have a sports car I may as well wake them up earlier so they can frown for longer!!

Cheers

Take it you mean removing the wadding from the back box? I had this done on my Griff500 and the noise is louder, but not unbearably so. Pops and bangs more too. I still have the perforated pipes in my exhaust, think this was a mistake in hindsight, wish I'd had straight through pipes to make it even louder.

Or you could always do what I did, and fit a Clive Reed equal-length primaries tubular exhaust manifold, remove the cats and remove all silencing. Then get TVR Power to race tune it as well. Four tailpipes, each of which produces more noise than an F16 on full reheat!

Interestingly though, I've passed speed traps and been followed by traffic cops on numerous occasions, and have never been stopped. Seems that they just *expect* a TVR to be this loud!

The halfway house seems to be removing the wadding from the back box, but leaving the perf pipes in - some tracks will let you on, others won't. Possibly get around this by using the Tower View Race serv. plug in silencers. Having heard one done as such sounds excellent, but not *excessive*. Straight through with de-cat is a bit silly-loud though...

When you modified your exhaust did you notice any power loss, and if you didnt how much did it cost.
