When I bought my 88 944 turbo, the muffler had been broken off. The exhaust piping is in fair condition, but there is no muffler. Is there any benefit to upgrading the entire exhaust system to say, a custom 3" with a aftermarket muffler? I've heard of some people using a Flowmaster.. would a simple flowmaster (40 series?) with my stock piping work? I was just wondering what my options were.

thanks!

lindsey racing makes a great complete exhaust system for really cheap

Yep, especially just getting the cat out of there will make a big difference.

Ok guys, what is better/recommended:

1) Removing cat keeping current stock pipes

2) Replacing system with full 3" (stock is 2.5")

Would there be any difference (minor say 5~10hp or major like 20+hp) ?

Buy the Lindsey 3 inch exhaust
if you want it quiet get the tip they sell
Best bang for the buck.
Its only loud when the boost hits

Sounds like a truck with the flowmaster, I replaced mine with a the biggest straight through I could fit. Now almost stock quiet and flows more (had to turn down my boost controller to bring it back to 15psi).

hally,
What brand and size muffler did you end up with? Oval or round? I would like to get a straight through muffler design, but don't want it loud or wraspy. I've been eyeing the MagnaFlow series, but don't know what length, shape or size.

I have the eldelbrock square muffler with the tip
its quiet and deep. You can hear the boost

krickman, ended up with an oval 3inch straight through muffler, seemed to be a generic / no name brand made here in Aus. Bigger + heavier (more packed fibres) == quieter was the advice given to me on the straight through design by my local 'muffler man'.
