rob wild Posted January 17, 2008 Share Posted January 17, 2008 Right then i think i've made a decision over my exhaust choice and have some really good prices but which one? Im looking for something that is not going to be restrictive (as my current one is) but is quiet. So after listening to clip after clip on youtube the Tanabe exhausts sound the quietest. So would the Tanabe Touring Medallion be to restrictive on the setup? its a 80mm pipe with 115mm tip and looks like there is only i silencer. Or would i be better to risk the: Tanabe Ultra Medalion which is 90mm pipe 115mm tip with one rear silencer and a removalable baffle. Help!!!!! Has anyone got one of these? Its just my new neighbours dont seem overly impressed with the noise of the car as it is let alone if i fit a really loud exhaust. Link to comment Share on other sites More sharing options...
Wez Posted January 17, 2008 Share Posted January 17, 2008 80mm (3") should be enough, my exhaust is the same diameter from the turbo back. Link to comment Share on other sites More sharing options...
Nic Posted January 17, 2008 Share Posted January 17, 2008 Medallion Touring - 92Db Blitz NUR RX - 92Db http://www.blitz-uk.co.uk/images/products/variantimages/hires/Nur-RX-Universal_1.jpg GReddy Ti-R (Titanium) - 91Db Not actual pic of the Ti-R as it has a second silencer on the mid pipe. I use one of these on my own car as it is one of the very few road legal exhausts from Japan. http://www.trust-power.com/01exhaust/images/petir01.jpg Link to comment Share on other sites More sharing options...

rob wild Posted January 17, 2008 Author Share Posted January 17, 2008 What egt's and boost are you guys running? So you think any of the above would be ok Nic? Also price wise whats the difference? Do you the Ultra would be over the top? Link to comment Share on other sites More sharing options...
Wez Posted January 17, 2008 Share Posted January 17, 2008 1.4bar and upto approx 850egt at a guess. Link to comment Share on other sites More sharing options...
Nic Posted January 17, 2008 Share Posted January 17, 2008 1.4bar and upto approx 850egt at a guess. Yes similar, EGT's will depend more on the mapping rather than restrictiveness of the exhaust though I would have thought. Link to comment Share on other sites More sharing options...

Do you the Ultra would be over the top? The Tanabe Touring medallion is only available from Tanabe USA. The Blitz would be around £430 delivered, the GReddy would be over £800 delivered Link to comment Share on other sites More sharing options...
rob wild Posted January 17, 2008 Author Share Posted January 17, 2008 1.4bar and upto approx 850egt at a guess. What exhaust have you got wez? Yes similar, EGT's will depend more on the mapping rather than restrictiveness of the exhaust though I would have thought. Yeah im sure they would be ok compared to my current one which is 3 siliencer and 2.5" pipe work oww man its heaven! (im not into loud exhausts ) Link to comment Share on other sites More sharing options...
Wez Posted January 17, 2008 Share Posted January 17, 2008 What exhaust have you got wez? Hayward & Scott custom downpipe and silenced screamer with Veilside Ti. oww man its heaven! (im not into loud exhausts ) My current setup is one of the loudest I have heard, I am in the process of having it all quietened down with mid silencers and routing the wastegate back into the exhaust.

Gaz6002 Posted January 18, 2008 Share Posted January 18, 2008 Has anyone measured a Tanabe Medallion Touring on a single with a noise-tester? I'm trying to find a suitable solution for the Nurburgring and can only really find those mentioned in this thread or a custom job. Link to comment Share on other sites More sharing options...

Ryan.G Posted January 18, 2008 Share Posted January 18, 2008 Yes similar, EGT's will depend more on the mapping rather than restrictiveness of the exhaust though I would have thought. Restrictive exhausts and Smaller AR housing always produce alot hotter EGT's. On a BPU TT with a 1ST Cat in place you have to run around 11:1 in order to just keep the EGT's at a safe level.

Nic Posted January 18, 2008 Share Posted January 18, 2008 Restrictive exhausts and Smaller AR housing always produce alot hotter EGT's. I presume you would map around these though to keep EGT's down? Would you say a 90mm compared to a 80mm exhaust would make much of a difference? Link to comment Share on other sites More sharing options...

That comment has confused me Ryan. perhaps you can explain a little further. My car is BPU TT with the 2nd cat still in place. As I understand it though there isn't a lot required to turn a TT BPU, and this may be ignorance on my behalf. Decat, Exhaust, plugs, fcd - I haven't a boost controller. So effectively by simply removing a Cat I have to run lower AFR to keep the EGT down? you seem to be implying that If I remove the 2nd the AFR will go back to normal. Sorry for my ignorance.

Ryan.G Posted January 18, 2008 Share Posted January 18, 2008 Do you have any recommendations as to make with a sport cat to keep Mr MOT happy and EGT's safe Ryan ? Sorry i dont. I just recommend either fitting a 2nd Decat back in for the MOT which is a Piss of piss or just throw the nice man a pack of lager Link to comment Share on other sites More sharing options...

Would you say a 90mm compared to a 80mm exhaust would make much of a difference? Yes if there are issues with high EGT's and the timing being correct you need to richen up the mixture to keep it safe. 3" is fine for any car under 700bhp IMHO but 2.5 system do start to become a restriction as i found on Rob's car over 500bhp Link to comment Share on other sites More sharing options...

Ryan.G Posted January 18, 2008 Share Posted January 18, 2008 Mike I forgot to put *1st* in my reply. Look Again I was talking about actually mapping a BPU TT. I found that with the 1st cat in place you have to keep the AFR fairly rich to keep the EGT's down as the restriction which it causes is huge with regards flow and being very close to the turbo's it makes the EGT's Sky rocket. On a stock ecu though you will be fine as they run around 10:1 at the top end anyway but i would not suggest running 1.2bar with the 1st cat in place.

I cant get my head round this, or maybe im being silly....so what the score with a full stock exhaust system in place then surely thats even more restictive but cant be as bad as you mentioned re high tempratures otherwise it wouldn't have left the factory like it?? do you mean a first cat in place and a boost controller to up it to 1.2bar, in which case I see what you mean about extra heat being generated?
