- Price should be lower to Supersprint quad what is my other option, preferably lower to supersprint OO exhaust
Money conditions allow me to purchase only in second half of January 2010 as earliest.
The 147 GTA stuff won't be ready until at least January 2010 anyway, as everything is getting done outside of working hours, weekends and evenings, plus there is about 50 miles between me and the Wizard, which doesn't help..
- in case you do straight 147GTA fit, its the best one for me, but if not possible, just the box is acceptable and I can have the tailpipes and pipe connecting to centre part custom made locally.
As you are so far away, it might be easier just to send a backbox, which would making shipping a lot easier and cheaper..
Are you planing a centre section that could be bolted on OEM cats? I dont want de-cat. And I would be interested in it if it had a silencer. Otherwise I will use supersprint silenced center section. Basically I want the unicorse sound, but I dont want it to be too loud as my target for future is 200 cpi main cat, custom manifold without precats and equal lenght front pipes.
Sorry - I forgot to mention. The decat section incorporates a large silencer, because this is where there is most room for it to fit, instead of having it on the centre pipe. The silencer is designed internally to increase the pitch of the noise, you can probably tell the difference between my tunnel run video and the one of the GTA with just the backbox. But even with only 1 centre silencer and no cats (as it is on my car) its not really what you would call a loud system. Volume-wise it is on a par with Swanny's 156 GTA with Supersprint cat-back system.
I'm happy with my supersprint cat back but would be interested in equal length front pipes and twin sports cat setup if that's part of the offering.
Equal length front pipes are difficult to do, the GTA exhaust manifolds end in a different place to CF2 156 V6 ones, and also the oil cooler take off is in the way on a 147 GTA, also the front pipes are two seperate pieces, on a CF2 2.5 V6 it is a Y-section. The only feasible way of making equal length front pipes is doing it on a car. We can make 156 2.5 V6 CF2 front pipes, as we have mine jigged so know exactly where the flanges need to be, where the bends need to be etc.
You're going to have to solder two resistors inline with your rear lambda sensors to keep the engine management light off, as you have no manifold cats. But other than that, it will be fine. Your's will probably sound the best of all, without those manifold cats but with the bigger bore of the GTA system..
