Hey Guest one of our sponsors Progressive Parts is running Black Friday and Cyber Monday offers - more details here
They took me trusty DA and my brand new rotary willie****, that sucks
Time for a rotary then
A lot of boxes. Cant ascertain exactly what because forensics still have to come and check for prints.
H&S 3" DP and Turbo Outlet Redesign Update #2
Got the car back this morning! The downpipe exhaust size is massive compared to the Miltek one. Initial impressions of how the car performs is positive. I wont say much now but lets say a newish Carerra S was a little shocked when I was road testing the car.
Pictures didn't come out very good so will have to wait till next opportunity presents itself to take some.
H&S 3" DP and Turbo Outlet Design Review
Done a lot of driving and running around this weekend so this has put me in a good position to give a “small” review of the new exhaust and turbo outlet pipe.
Scope of the upgrade
I went for a full 3" Exhaust System for the following reasons.
1) Remove the restriction of the Miltek DP. The miltek DP is very good however the outlet of the downpipe is still stock and only goes to 2.5" once past the metal flexi part. This is fine for standard 150PDs and Hybrids however in the quest for more power going bigger is the only way. This also will set me up nicely for if and when I upgrade turbo.
2) Lower Exhaust Gas Temperatures! In the quest for more power its essential to keep the temps in check and with the older exhaust setup it was always in the back of my mind. If I want to do a long trip and track the car on the ring then I want lower EGTs for sure. 3" DP should flow more and thus reduce EGTs. Hopefully turbo will live longer too.
3) Lower noise. Ever since I got the new tip and the 3" piping to center silencer the exhaust was much louder than I liked. I some occasions it was nice to hear the wastegate chatter and the roar when accelerating. Other times I thought it was just too loud and not what the car was about. Knowing that 3" would increase noise I opted for 2 high flow silencers instead of one.
4) See if there are any performance improvements. the 17/22 Hybrids produce amazing results for the size of turbo they are. Some people say 2.5" is more than enough and even fewer say 3" DP improves anything at all.
Sound
When listening to the car on idle the exhaust note is now virtually non existing compared to before. The sound before was very hissy however now the hiss has gone. There is a burble especially now I added some miles and the car warms up but not a massive one. Inside the cabin however the engine note is now a lot lower but louder and it growls nicely when bliping the throttle. When driving normally there is a low gentle burble and definitely a lot lower noise than before. Changing gear there is not hint of a pigeon noise from the back either.
The exhaust really starts to open up at 3.5k. You get a lovely throaty sound but without the same high decibel roar I got before. It certainly makes the car feel grown up and expensive now.
Power
Squeezing the throttle you get power delivery that is now much more immediate. I would love the see the graph because it definitely feels like there is more power lower down. Definitely smoother power delivery and knowing that I said this many times I just can’t believe that there can be so much improvement from freeing up the exhaust. The power delivery was silky smooth before but now there is more torque availability lower down and it doesn't seem to tail off! The Miltek DP and centre silencer must have been more restrictive than I first thought. I am trying NOT to sound too enthusiastic about the difference as I am well aware that many of my previous performance mods made things more powerful and smoother. However I am beginning to wonder whether now I am at the limit of how smooth the power delivery can be with this turbo…seems too good to be true.
Past 3.5k that’s when things really begin to get interesting. It feels very much like a petrol in the sense that the power and sense of speed keep building as the revs climb. At 4K there still seems to be plenty of puff and the engine doesn’t sound as strained as before.
Playtime
As I stated before I had a little play with a new Porsche Carrera S within the speed limit of course (believe they are now 3.8ltr units instead of 3.6ltr and pushing an impressive 355bhp). I think the chap was a little shocked at what he found when he tried to stick on my bum when I first started to test the exhaust. Definitely felt confident in accelerating with the turbo outlet sorted and the new exhaust. I made a good account for myself and I think the fact he could over take me must have annoyed him no end.
Pros
+ Droning noise gone at 70mph
+ Great torque delivered more smoothly
+ Nice and quiet when driving normally.
+ Sounds grown up now and suits the car better
+ Definitely more performance. Might not be bhp but its added something!
Cons
- Expensive
- Got an annoying rattle because its so big. Can be sorted though
- Bang for buck may be lower in the grand scheme of things

One poor soul will find it of use someday.So far so good. As the maf was off for a week it messed up the adaptation so its been getting stronger and strong since I been driving it. This will explain why H7S said it felt a little slower when they first drove it.
Turbo outlet: welded a short 90 degree bend directly on the SFS connector. They then swaged the edge of the 90 degree bend so they can attached silicone to a straight section. This will get more movement and likelihood of it popping off is next to nothing now.
It's nice to hear that the car is back to its' best, in all respects, Maz. I know you had a good paint correction session recently but what do you have in mind for winter protection? I hope your home insurance covers the loss of your equipment.
I've read that you've been a bit frustrated with your car of late, but are you feeling more content and motivated to carry on with it now that it's back from H&S? Cars and emotions often clash and over the past seven or so years, I can vouch for that! My mechanic has an RS4 on a 2001 plate and it's very very nice (425bhp). It would be a real shame to see it go; you've put a huge amount of time and effort into it! For me, having a nice car is a hobby that I enjoy and is a reward for the hard work day to day. Cars are always financial blackholes and if your heart is not in it, then may be it is time to move on; this will be my prompt to move on but I just can't see that happening yet.
For reference Maz, I used the Megs Ulitimate Quik Detailer at the weekend after a layer of Dodo wax and it appears to be very user friendly and gives great repellent to the rain (beading). I haven't yet used the Ultimate Quik Wax.

The products used in the detail should see the car through the winter however I may stick on a coat of wax or more in the coming weeks/months for reasons that will be clear after this post. Speaking of detailing I clean the engine bay and noticed some scuffs on the engine cover (argh!). detailed the whole engine and dressed all the rubbers and plastics in a way I never had done before. Results are amazing., everything looks like new.
Home insurance origionally did not cover the equipment as they are classed as "car accessories". I successfully argued that they are not car accessories and can be used all round the home for DIY. To be honest I am not that bother about the polishers in the sense that thousands of pounds of my mothers stuff I was temp storing for her are gone. Losing a couple of polishers, makita drill and some snap-on tools in the grand scheme of things is nothing. We live and learn!
I am feeling a bit more content now its running superbly. Had a chat with Shaun@AmD and he said that I made the right choice keeping the car as a huge amount of work has gone into it. Not only from myself but AmD from the choice of mods to tweaking the suspension and engine performance out of it. There was a small rattle from the exhaust that H&S and I sort of tracked down. Very slight vibration coming from somewhere at 1800rpm but we couldnt 100% isolate it so going to drive it for a while and check to see if there is any obvious signs of wear.
All in all things are looking up. Just case of maintaining the car at the moment and working with Slick on the intercooler design. Going to get a few items powder coating keeping OEM+ look as much as possible and 3 wheels refurbed (no curbing just the lacquer has starting to milk where a stone chip has hit the polished face).
nice to hear you are keeping hold of the motor, as said a lot of time and effort amongst other things have gone into her so it would have been a shame to see her left unfinished in a way
Cheers Chris.
Cheers, hopefully the feature bears fruit.Glad to hear that the insurance covers your losses!
Is there going to be (or can we/I get) an video/audio from the new system?
Congrats on the Magazine feature!
