I'm having a decat done, and then I’m going to focus on the back box.
What’s the thoughts on the best back box to maximize noise?

Racing Green/TVR Power rear boxes (2 very small) sound absolutely amazing with decat but no good for trackdays and depending on your neighbours could possibly earn an ASBO!

Slightly off topic.... Are the TVR power and Racing Green rear boxes made by the same company?. I want a set for my Tam but not sure who to spend my money with. I will fit them myself and from memory three is little if any difference in cost.

Back boxes are for wimps - what you need is a straight through system.

Without trying to sound like a spoil sport... A Word of warning...

I bought my T350 last year, it's decated with a JP. I loved the noise when i bought it, the pops and bangs on the overun are fantastic. After a few 30 minute drives in the first week my ears were ringing constantly after a run like i'd been at a rave all night.

I bought some ear plugs and now have to wear them all the time otherwise it takes my ears over a week to recover. I was at BNG last year and it was sound tested at 135db - The loudest there on the day. I've since found out that anything over 85db can cause permanent damage. 130db is equivelent to a jet engine at 30m. Sounds cool but the novelty soon wears off.

I'm now getting pissed off (as is the wife) at having to wear plugs all the time. At the risk of being called a massive gay i'm now seriously considering putting a standard exhaust on or some better silencers.

In fact if anyone has done the same (gone quieter) i would be interested to know the results???

You're not the only one:

...and I recall one or two others - try the search function.

Seemingly though, most are looking for increased aural pleasure - I'm looking forward to getting back to the UK where I should have some of NTEL's decat pipes waiting for me smile

TVR power and racing green are the same boxes. I would keep the cats myself because its just too loud with them removed. On a tamora the noise is ok, but on long tunnels I have been know to pop some ear plugs (100 in 1 day on a Monaco to Bologna run)

Just read RubyRed's post. I've had a similar experience - the tam came with a JP back box when I bought her back at the beginning of last year. It sounded great - put out a delicious note when at idle, made some serious noise with firm application of the right foot and the pops and bangs on the overrun were fantastic.

After about 6 months, however, I too became really frustrated (and concerned) with the constant ringing in my ears after a +30 minute drive. I resorted to ear plugs but missed being able to crank-up Pearl Jam while doing my sunday morning drive through various b roads outside of London.... So, I took the plunge and picked-up a used standard back box and made the switch.

At the risk of sounding like an old man, I must say that long drives (esp with the roof off) are much, much more pleasant now. I do miss the sensational note of the old exhaust and the pops and bangs, but I certainly don't miss the headaches and the ringing in my ears!

You are a massive... Nah, I wouldn't... wink

Is it a full JP or just the back box? Be happy to swap my frustratingly quiet back box with you if you really want to get rid... biggrinwink

JP,

They look good through the rear diffuser as well?

I've got Power boxes on mine (without decat).
If I'd been at The Railway tonight you could have had a listen, but I was late home. Do you want to meet up for a pint sometime to exchange t350 stories!

Hi John. I've had it done.... NTELS decat pipes with a JP sports back box. Sounds good.
Let me know if your around sometime, and we can do a sound test.
Cheers. BB.
