Last weekend I removed the cat of my RC and fitted a 'straight'pipe. Here's a small video on youtube what do you think

It sounds good, does the car feel more responsive without the cat?

I had a straight through pipe that sounded abit similar on my gti 140, sounds nice. notice any difference? my gti is the first car ive owned with a cat. Have allways fitted de-cat pipes to both my 306 gti6's noticed abit of a difference mid range and was abit better on fuel.

Exactly what you said Rick, (lower)midrange is more torque for my feeling. And I mentioned to that the fuel consumption was a bit lower, something I couldn't imagine.

Klink baie mooi. Ek hou baie van daai pop geluid. Dit klink net soos my 180 
Do you have your backbox vertically or horizontally mounted and is it oval box or round box. Mine pops just like yours except my exhaust is more quiet

@Icetto: it's from manifold to tailpipe's almost a straight line. Not like origenal were the backbox is fitted in place of a spare wheel. I've fitted a JanSpeed and yes it is pretty loud now
@Kingdom200: I personaly think a cat is still an restriction so there is some improvement possible. There are so many theories and visions about this. When you measure before and after you now the gains or improvement, thats all I say

The JanSpeed is 62mm. what I've read, the decat was an origenal cat wich cut'd between and replaced for a tube. Looks similair to your solution.

I read many threads on here highly recommending not to decat.
I decatted my 106, i loved it, it was bloody loud and droned alot but was epic.
Yours sounds awesome, what is it like inside the cockpit? is it easy to swap for mot?
