Morning!

Did anyone else have a problem with the back box rubbing on the rear sub frame? I cant seem to get it far enough away to not rattle......3-4k revs on down shift is when she rattles and its pissing me off! I dont want to simply lower the back box at the tail pipe end as that'll look s***!! Anyone got over this without notching the sub frame that I really don't want to do !!!

Thanks!

 

Bit odd mate. You sure you have the right exhaust for the year of car?
We tried a classic system on my blob and it knocked against the prop and the rear diff under load.

 

fitted a 3 inch cobra yesterday, no problems at all

 

It was brand new from cobra so should be.....where you've got an inch clearance I have 3mm!

 

new or not its still the same shape. should be able to adjust it a bit if its for the correct car

 

What centre section has it been fitted with?

Cos if its anything like a miltek it will only match to that as they are offset, Get it hanging on all 3 hangers and have a loot at where it lines up with the centre section holes, You might need either a matching centre section or a bit of fab work to sort it.

 

that was my next question is the exhaust all the same or loads of different manufacturers.

i made that mistake a few years back and the knocking drove me mad

 

I've changed enough of em to fall foul of it myself Tubbs, Ive had 3 on my spec-c in the last 18 months, Got a 3" backbox and a 2.75" Miltek backbox in my garage, I really need to have a clear out

 

sold my miltek on here, ballache to post it though

 

It's all one cobra system that I bought 2 weeks ago from cobra.....other than with a hammer there's no adjustment and even that would only serve to lower the backbox ruining the tail pipe location in the rear bumper.....can only think its made wrong :/
