Trust PE2 is pretty rowdy when you smash the go pedal. But normal driving its really nice.

Lithium has one on his R33 with GT3076r. Its beautiful to drive/ride in normally, and then gives you the heebies when it opens up. Just roars.

We are currently working on some comparison clips. Will post up if we get some dry weather.

=/ i had a Trust PE2 before and thought it was way TOO loud...droned too much for my liking too.

Replaced with 3.5 x-force catback mid muffler and rear cannon.. better but still loud and droney.

Cut off rear muffler and replaced with a 3.5" varex - MUCH better. The varex mufflers are very large (as they need to have enough room to make 3 chambers for the gas to flow through in silent mode) so even at full open mode it's not too loud/droney and it sounds good too. Had to get the mid muffler repositioned too - thing was too low like previous posters mentioned and was scraping when attacking corners that were bumpy.

Now I don't have an R33, but I just fitted a 3.5 inch CES custom exhaust to my s15.

I thoroughly recommend it as it is not loud nor drony. I previously had their 3 inch system on my s15 which they claimed had legal db's and I can honestly say there 3.5 inch system is NO louder even with a 100 cpi cat. It has a large oval mid muffler and large oval twin tip muffler (with twin 2.5 inch dual skin perforated outlets) which are custom made at CES.

It cost me $1600 plus freight. Now that might be a little more than your willing to spend but...but what extra price do you put on a drone free and reasonably quiet exhaust?

I live in Perth and the exhaust was custom made at CES in QLD and yet despite this it's a beautifull fit even though the car was not there...tucks up nice and close to the body.

Also has twin tips as I wasn't keen on the cannon style to which Trevor at CES advised it would be slightly louder with the cannon.

Can snap some pics if you want to get an idea of the quality and fit.

sorry guys, let me clarify, i want the loud exhaust with no drone, i understand this is hard to accomplish without spending big bucks :rofl:

You can't.

If you want a loud exhaust, it's going to drone @ low RPM. That is how sound works.

You can't have it silent and then suddenly loud legally.

You'd need to buy a valve of some sort that only opens above 2500rpm or something.

End of the day its always subjective anyway.

What some people say is "fine", is ridiculously loud to someone else.

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
