Engine 'chugging' intermittently

[peteinnit]

Hi all,
I had my 2ltr Aircooled tuned a coupla weeks back and all was great for a trip to Wales. In Wales I then carelessly reversed into a stony grass bank and since then it's been 'chuggy' sometimes, more so when going uphill, other times it feels normal. The bank put 3" of earth up the tail pipe (removed), and bent/split it away from the silencer joint which I have managed to bolt back together so it's not blowing and there is a small dent in the silencer about 2" diameter and 1/2 inch deep. My question is, would this dent impact performance in the way mentioned? I can't see that it would have done anything to the engine set up, but if the exhaust isn't likely to be the culprit I'll have to try and find a mechanic near Fairbourne, Wales.

Any advice appreciated.

Thanks,
Peter

Generally speaking if everything is fine until something happens it’s probably the something, it’s quite possible a baffle has become dislodged and is floating about

Yeah that makes sense, which i guess means a new exhaust, when i get it home. At present it's got the standard exhaust, is there any benefit in getting a 2 tip system over the standard? Cheers

The cheapo 2 tips don’t fit a t25 , I would keep stock personally

If you mean the 2 tip GT exhaust from JK, then go for the stainless steel one. The empi one splits in the middle in a short time. Ask me how I know. 
as for difference, probably only the sound, unless someone else has a different opinion. 

ahh, you have 2l air cooled, my engine is standard early 1.9DG so unsure if it fit yours - sorry, should have read closer before replying.

Seems to be a bit of a minefield which exhaust supplier to choose, from reading through all the wikis on the subject although there's not many posts about the Aircooled. Think I'm gonna stick with stock, as I don't wanna mess around with the rear valance. Brickwerks seems to get consistent good votes, don't think Speedshop do one for Aircooled, have asked them and also JP. Justkampers s/s seems to get mixed reviews. Any others I should consider?

Cheers

Take exhaust off and see if chugging stops.
Sounds like you have exhaust restriction due to the mishap.
