hi folks, thinking of selling my scorpian exhaust which is only 2.5" and maybe buying a piper or mongoose, the exhaust sounds lovely and pops quite loud but want the pops and bangs even louder. currently im running de-cat back, my options are
1: piper catback with mongoose de-cat and downpipe (maybe too loud?) loud pops?
2:full mongoose system (louder than mine)
3:add mongoose downpipe to mine ( any louder)
i was thinking i might get more noise and pops with a 3" system over a 2.5"
any advise and/or sound clips would be great

Yes it is a bit boomy on the motorway.
You can just cruise at 70 in 6th and its ok but as soon as you hit a bit of a hill and you have to put your foot down it becomes boomy. It doesnt bother me and I dont do a lot of motorway driving anyway. Dont know what it would be like with a mongoose cat back but it maybe a little quieter.

I ran a full Magnex with decat for a few weeks and the cruising boom was awful. I felt it totally ruined the car
It went away if I floored it but for everyday driving I just hated it and refitted the standard cat until I got a sports cat.

Still need to drive my mate's ST with same combo apart from Mongoose and see if it's the same when cruising, might just be something with the cat-back I bought.

If you find boom too much i'm selling a new Mongoose Sports cat

Thanks for the offer troy, but I like the boom!
tbh if I drive it normally and just cruise Ive found it not to be too much different to the piper sports cat that I changed from, but its certainly louder when giving it some. It makes it sound faster than it actually is.
