Call me stupid guys but what's the difference between cat and turbo back?

just been down to this place http://www.longlife.co.uk and got a quote for a new exhaust, they have done them for my motorbikes in the past.

From the Dpf to the rear single exit they want £249+ vat

From the Dpf to rear with double pipe its £349 +vat

You can choose what tips you want, they say it doesn't need any back boxes on and it will give it a mild-mid sport sound

Thoughts??.

Can anyone recommend a decent rear splitter for my J 5 door to look good around my exhaust system that I'm looking into? Having a Powerflow single 3" slash cut either side but want to get a decent splitter before hand.

Hi all

I'm SURE I saw a post on how to fit a visible exhaust tip to the J by just cutting the splitter & bolting an eBay tip on.

May have been @tucpal ?

I can't remember if you need to angle grind the downturn off or not, I'm hoping I can do it without welding as I have everything but a welder!

If there's no how to, can anyone help with what needs to be done? 

Cheers

Has anyone had the front flexi pipe replaced on a 1.6vvti astra J by Vauxhall? if you have can you remember how much they were fitted?

Got a price from Kwik fit and they are quoting £115 fitted but just wondering how that compares to Vauxhall

Thanks

Hey All

What do you all think of these exhaust tips? I personally LOVE them! I don't have any exposed exhaust tips at all so really want one of some kind! Anyone know if these are the merc ones?

Hi all,

I'm after 3 oval exhaust tips like on our 2.0 cdti's. So if you or someone you know is selling please let me know!

This is what I'm going for.
