This may sound like a stupid question..

I need help with choosing whats right for my new exhaust set up as im new to this..
Ive currently got a ma70 7mge and I was thinking about cutting off the old muffler and tip and get a new 2.5inch in and twin tip 3inch out, muffler. Im on a tight budget and this seems like an easy option as I can source this cheap but will this be bad for back pressure? I just want to get ride of the old exhaust and make it sound a bit louder but not lose any power whilst doing this.
cheers.

The rest of your piping is xx size. so your muffler isn't going to reduce backpressure. If you changed the whole exhaust from the manifold down to the muffler to a bigger piping. You in theory would lose some of this back pressure.

ah thats true! thanks but hypothetically speaking, would this set up help make the car a tad louder?

1) Backpressure doesn't exist

2) It depends entirely on the muffler design in how loud it will be.
