Need exhaust system advice

[fastjack1]

Need exhaust system help, Who sells the quietest two and a half (2 1/2) stainless exhaust system for my 87 GN. I currently have a 3 inch ATR system and pit bull muffler on the car and the drone noise drives me crazy. I am done racing the car , so I don't care if there is a little performance penalty. The car will only be street driven for as long as I own it. Thanks, Jack.

With a 3-muffler system you can have the quietest exhaust with no drone at all and lose little to no flow at all but it's a custom system and it's not cheap.. Are you concerned with $$?
Do a search on "3-muffler". There is a HUGE thread on it even with test results and this is what I put on my car last Fall.

do you have a 3" atr single shot, or dual?

It's a single system, 1 muffler & 1 tail pipe.

if you are looking for the cheapest quickest and easiest, the pypes sytem would be fine.

I am willing to pay whatever it costs to get the quietest stainless system available.

The only "production" exhaust system that I am aware of in 2.5" is the pypes system and it's 409 stainless which is barely better than mild steel. If you go to a 3" there will be more options...

I believe Kirban carries the pypes system.

I have this system on my car too. It's very nice and sounds great. I drive my car to Norwalk (320 miles round trip) and Columbus BPG (700 miles round) it cruises at 70 and no issues.

I have driven a car with this system and was very impressed with how quiet it was inside. The car has a 274" stage 2 engine in it, which would tend to be louder than a stock engine, No drone while cruising, barely hear it.
