So, i've had a busy morning today fitting a Trust air filter, Apex Dump Valves and a Grounding Kit :)

 

All went well, and really happy.

 

Bad news is, my exhaust plans have changed...

I currently have a twin exit Kakimoto exhaust, which sounds lovely. The right hand back box though has blown it's baffles out, so the plan was to convert it to a single exit system (so i can keep the Kakimoto).

 

After starting it up today and giving it some to test the dump valves, i've noticed the left hand back box baffles are starting to blow out too :(

 

So, long story short, i'm going to be now looking for a new exhaust. Think i'm going for a quad system but what is general regarding as a good exhaust?

Anyone have a quad tailpipe system they can recommend?

 

Also, i've heard with de-cats that you can get premature turbo failure... is that right, or is it more like the de-cats show up the turbo failure earlier?

Never had one but I hear Mongoose are a good quad system mate.

I have a mongoose on my tt it's quite quiet but a nice noise.Probably a bit quiet for you compared to the kakimoto.

I have the Mongoose as well - it's louder than stock but still quiet enough not to be a nuisance. I believe the Japspeed system is a bit louder; and an excellent bit of kit too. Plus it's good value.....

 

.....as for decatting causing premature turbo seal failure, it doesn't. More like it just shows you that the turbo seals were already on their way out - more smoke will probably be evident without the cats to block it out!

 

Richard:biggrin:

ive got the japspeed with standard pre cats atm, its loud but not too loud. you can sit on the motorway at 70 without hearing it over the road noise. apprantly that will change once i decat haha

Cheers guys, think I'll go for the Japspeed one.

I'm not overly fussed about motorway noise etc as its not a daily runner and the only time it will see a long journey is to a show etc.

I actually find the kakimoto a bit droning to be honest so even if the Japspeed one is, I'll be used to it.

 

In terms of turbo seal failure. What smoke am I looking for? White? If they did fail, what's the process, is it new turo time or a simple repair?

iv got the japspeed system aswell

just added the manifolds as well

its quite loud

worth every penny though

i put a video up the other day of how it sounds

Sounds well, completely different from my curren sound which is quite a deep note.

 

Like it :)

The best ever quad for looks and sound is the abflug one. but i doubt you will ever find one :lol:

Ive a pair of mongoose quad exit back boxes (just the boxes and tailpipes+hangers) going cheap in good condition if you need them..Lee

How cheap is cheap lee? :)

Pm on its way:cool3:

Looks like I've got myself a new exhaust. Thanks lee :thumbup1:

 

I love this place :)

well done

that was quick

I really fancy the Japdspeed complete system,

but their website states that these systems will not pass emissions.

Is there a way around this?

Surely it is going to be below 3.5% Co?
