Right so ive narrowed my exhaust choice down to piper and GT3 mainly due to design and price.

Anyone know how good either of these sound with just a backbox?

Or is it worth getting a cat back system? Also is it a straight fit on a cat back? Or is there slight cutting to do?

Cheers for any input :doublethumbs:

Piper or custom made tbh

piper is a straight fit yes and wont notice much of a difference with just a backbox with a cat-back system with straight through centre section you will :love: the sound of it.!!

Also on a catback, could I just get a GT3 centre section on a piper backbox? Since there only like £30 or something lol

Piper are better, but GT3 are cheaper. GT3 sound seriously rude, really throaty. I have the catback and it's a piece of piss straight fit. BUt if everything was equal I'd have gone Piper. The only reason I chose GT3 was my car needed a new exhaust system as old one was corroded to **** and money was tight. But either one's a win IMO. :yes:

I'd say not, but only because I've heard of people having a hard time fitting Piper onto other things (I THINK). But if you find out what bore size they are then you'll have your answer.

Hmm, sounds good imo, straight fit from the catback? Got a few things to pay for this month as well, so edging towards gt3, purely because i can get a catback and box for 130.

Cheers matey :)

Still a piece of piss to fit. Just whip out the angle grinder on the old pipe and youre away. Hangers are all in the right place and you don't need different rubbers. Plus they supply clamps.

GT3 are stainless but they're painted black. But tbh u don't see it under the car anyway. The back box is aluminised stainless steel and that looks mint. I've got the twin outlet box.
