The CAT restricts the exhaust flow which blunts power.

Also, if you fit a tuned tubular manifold it takes the place of the cast lump and CAT anyway.

It also sounds raspy, if thats what you want...

Trouble is, what happens if you're pulled and they do a spot check?

I've seen the local fuzz carrying out roadside MOT's on random vehicles here before. If you're pulled with a decat pipe you're screwed when they check the emissions surely?

usualy give you a 7 or 14 day notice to get it changed and approved by a garage round where i am mate. then when its sorted people just change them back lol

[lharrowing]

just hope they dont know much about cars and theyl prob look under car for cat just say i think its in the manifold on this model to which they will hopefully be stumped!

Usually costs me about £5 to put back on. GunGum paste cost, thats all.
