sports exhaust

[lovemytvr]

Have heard of people talking about a sports exhaust for Chimaera - sounds better than normal?? (Is that possible?)
Any ideas of costings and how do you know if you have already got it on the car??

Any advice appreciated
Thanks

I have a 98R Chim 4.0L with a tvr stage 3(so I am told which means its the loudest you can get without removing the cats) sports exhaust the car sounds so much better, you wont beleive the difference fantastic right through the rev range, you get all kind of pops and bangs at about 2800 revs. It sets off car alarms at about 20ft ha ha just hope you have got good neighbours, fortunatly mine has a griff 500 !! I think if you have it done at a specialist or a dealer its about £150 - £200 and involves them cutting the baffles out of the existing exhaust the best thing that has been done to mine

Depends on how much you use the car I think. We test drove a Chimaera 4.0 with a sports exhaust but while is sounded fantastic and was really noisy I'm not sure I could live with it on the daily commute, not sure what type of conversion it was either but worth bearing in mind.

I've had one of Zertec's fitted for the last two years and it sounds better than it did when first fitted. Rolled ends look good too. It's a replacement for the system from below the cats and makes it sound burbly, with a few pops and bangs on overrun.

I have a 3-qtr sports exhaust on my 4l Chimaera- not as noisy as a complete fit - and it sounds luvvly....far better than before...richer, bassier and oh ! that burbling sound is soooo much nicer It cost £100 at a specialist.

Mad is the only way to be

£100? is that all, what company was that with?

Have you guys had any problems getting in on track days? My Chim 500 has an especially quiet Swiss regulation exhaust (apparently the factory ran out of std units so fitted one of these export units to my car).

I know I'm missing out on a lot of great noise, although the car's still pretty loud. I'm reluctant to change it though as currently I know I'll have no problems with the noise regs at track days. Do you know how many dbs these sports exhausts kick out?

Out of interest, what did you do with your old exhaust parts, they cant be knackered being made of stainless. Were they traded in?

MarkBigEars,

If you would like to know, please send me a mail. My address should be in my profile...

Seriously thinking about it,but heard it can shake itself to bits, which kinda sounds expensive...anyone know where i could get it done in berkshire (if i decide to go ahead). got to admit they do sound the nuts modified) :-)

[rivergirrl]

Gowan, I had mine done (ooerr) in Berks...mail me for details. Once you you hear that lovely modified sound, you'll wonder why you didn't do it earlier

rivergirl, you got yours done for £20 less than me then, I'll have to send my wife next time. btw did you have a letter in Sprint this month

Anything upto 110dB depending on how it is done. 105 is common. As places like Oulton, Goodwood, Castle Coombe are all around 98 dB, it can be almost impossible to get on these tracks with a sports exhaust even with a silencer insert. As noise regs are only going to get tighter or more strictly enforced, this problem will get worse.

Steve, what is teh typical db level for "noisey" days?

[shpub]

Depends on the track. Noisy at Goodwood is 105 but it is at 3/4 revs not the normal 2/3. The 520 was quietened down with an additional exhaust unit when I got pulled at a sprint with 117db (limit 108). It is now around 101-102 at 2/3 but spot on 105 at 3/4. At other tracks it can be 101, 103 and so on. You also need to be aware of what revs they are using and how it is measured.

I had a sports exhaust on my Cerbera and it was getting a joke because I couldn't quieten it enough to go to many of the places I wanted. Given the choice of a queiter car and being able to really enjoy it... No question: quieter car.

Apache...no, I don't have a article in the Nov. Sprint...why? I hope to have a pic of my car in there soon, though. Do send your wife next time - works a treat when you smile

Madness is definitely mandatory
