would somebody please confirm if this deletes the midbox?

My backbox ripped off my estate when i had the 1.8 and it was fairly loud, quite a nice sound to be honest but without the middle silencer i would invest in a decent backbox for a nice sound

Back box seriously doesn't do much compared to the middle silencer. I ran without a backbox due to...ahem....loosing it on a country road, for a month or two and the car wasn't any louder than the standard exhaust, it was a bit throatier accelerating, but nothing even CLOSE to loud. Soon as middle silencer went and stuck on a small rear box, it popped and banged like a machine gun.

Now THIS is what I'm hoping for

lol!!
ive got rid of the mid box, and before it was all blowing etc, it free'd the revs up and have a really nice sound with a little popping!
worth doing!

Mind you I had a rally spec camshaft, so it did pop more than the average car.

Would it pass an mot without the midbox?

Entirely depends on the station. I have a 400bhp 300zx with 1 box at the back and no cats, and I had a prelude with the same setup - the prelude was rediculously loud even on Idle, god help anybody with sensitive hearing within 200 yards of it. both exploded like a shotgun off throttle and spat massive flames (the 300zx rediculously large). Both passed MOTs with no issues

Kl thanks iv ordered 1, how do u get the flames?

[polo6n222]

It will pass MOT no problems mate, silencer has nothing to do with emissions.

Well just fitted it (perfect fit by the way)... with the sebring backbox on the end it sounded crap.. seriously, crap!  quiet at idle raspy as hell with revs.. not my cuppa tea.


Left open it sounds lovely, nice deep rumble on idle and no raspyness until about 5-6k revs. The over-run sounds just mint but perhaps a little loud..

I can't test how it sounds with my peco bigbore 2 as the diameters are the same so will have to get my dad to hold it over tomorrow.

So going to the exhaust shop on Saturday, it'll either be the peco, or a bit of pipe with round tailpipes 

Sadly it's obvious what the lack of backpressure does, it seriously hurts the mid-range
