2.5" from the stock header all through with a flowmaster muffler. It's pretty loud when you're on it, coasting it's quiet. Can't talk on the phone while driving as it's very loud :)

Performs good. Needs a header ( but waiting to go turbo )

I use 2.25 inch exhaust with a single muffler, although it is quite loud and sounds like a rotor

I had a mate who used twin V8 mufflers on his gemi and it sounded like a beast, but it did have alot of work done to it.
Has any1 had any experience with fitting these or hotdogs to their system, what did it sound like?

I used to run a 2.5" single system on my 1000 coupe with A12
Racecar runs a 2.5" single also with a single muffler (A15)

Just wanted to know what exhaust system people are running to match the modifications on their A series.

I was planning on having an exhaust made up for my A12 which will shortly have high powered ignition, gx head, mild cam, single 32/36 dgav weber and 4-1 press bent extractors.
I wanted to have a dual 1.5 inch system made but was told that a single 2 inch system with a high flow muffler would be the best.
Your opinion and advice would be much appreciated.

thanks in advance
