2.8i Exhaust

Post by mwillerton »

Hi all

Do i need the Kidney boxes on the 2.8i exhaust?
Can i have an exhaust with just a rear silencer?

Thanks

No you don't, Performance downpipes are straight through. But without the middle Silencers it might be too loud ??

Do yourself a favour, get mid silencers! I had a 2.8 with straight a straight thru system, it ran well, loud as hell and after a cruise from Manchester to Blackpool for the show I changed them back to standard, the car acts as a resonance box and literally deafens you after 20 mins of cruising, if I hammered it my ears would actually ache!
In answer to your question, you don't need the kidney boxes at all.

Don't those kidney boxes have something to do with back pressure?

If they weren't meant to be there then why was the car built with them?
