what is the best 3'' exhaust out there?

[josh young]

I'm looking at replacing the exhaust on the GN with a nice clean new one. I have seen several offered and was just looking to get some of you guys opinions on whats the best. Would Flowmaster mufflers be the way to go also? The car has them on it now and I kinda like the sound. I found a nice polished setup from one of the vendors, just thought I'd ask first. Thanks guys!

From what I've read, flowmasters are probably the WORST choice for our cars. I plan on going with dynomax mufflers in the near future.

Yes you are right....Flowmasters are not a good choice because of very low back pressure...Choose a set from any of vendors here. And you will get a quality exhaust w/the proper mufflers for Turbo Regals....I run a 3" from RJC Racing myself Sounds real

Not low back pressure but high back pressure or low airflow.

I love the way mine sounds. I'm running Magnaflow 3" X 5" (3" in and out 5" body) race mufflers.
