Stock Grand National exhaust system

[UNGN]

Ultra stock TR guys are ****'d in the head. They completely fail to grasp what made the TR great and wasted the best 20 years of their life staring at a car parked in their garage/living room with every piece of rubber on the car slowly deteriorating, when they could have been ruling the track and embarrassing Vipers GTS's.

The Fuel pump was inadequate for a 14 second car and yet there are idiots that demand "the correct one". The Exhaust system is the difference between maxing out all in @ a 13.5@103 or running an 11.9@112 with the stock intercooler/injector/turbo... it is THAT bad.

I'm that guy back in the 1980's/1990's that had the correct date coded everything (including tires) on my muscle cars and the TR is the one car that showed me the error in my ways.

That is some candid honesty.

I have that setup, but not stock. Flowmaster makes an axle back setup which is what I used on my car. Goes from the rear y pipe to the cross mounted dual in, dual out muffler, mandrel bent pipes, and dual GN style exits behind the rear wheels. My car is not for racing, has no more than 350hp. Works for me. The reason I used it was because my car is lowered. I was sick of catching the dual mufflers hanging under the floor on sidewalks when pulling into parking lots.

My dad still hangs out with people that won't put a "incorrect" parts on a car. They're building a 67 SS350 4 speed Nova and they ordered 13 master cylinders into the advanced auto parts until they found one with the correct date code. They put the correct stamps on parts in areas nobody will ever see again (like the top of the gas tank or the heater core). It's a borderline mental disorder.

Every chance I get I ask them why they didn't put the correct 6 cylinder/automatic back in the car (since its a clone SS350).

My friend is keeping this 78 Cutlass 4 speed pretty much stock or should I say stockish. Car will never have more than one of those low performance Chevy 350 crate motors in it. The stock GN exhaust should work well for that and it's all a simple, cheap, bolt on system so that's good.

Still may go another route though. Just keeping options open.

It will if it is the flowmaster version. NA V8 don't care as much about the backpressure of a flowmaster system as turbos do.

A 30 year old original GN system would not be a good choice for anything, however. If you have an original GN exhaust that you still think can be bolted on a car, put it on craiglist and some late to the party, Nuevo GN owner will pay you more than it is worth (because he thinks a GN is like a '69 Camaro and the original exhaust is worth something) and you can buy something good.

I have a desire to use this on my MCSS: http://rjcracing.com/product/exhaust-systems-2/

Or build my own with one of these: https://www.magnaflow.com/products?partNumber=14386

https://www.magnaflow.com/products?partNumber=12599

We have the 12599 on the TBSS.

The single shot from ATR was pretty cool. ATR made good stuff, but with all of the aerospace and BMW moving to the SC upstate in the 1990's, they couldn't find good welders. We (Allied Signal Lycoming) were paying twice as much for welders as they were and WE couldn't find good welders. ATR's quality suffered because of it. At a Carolinas Buick Club meet ATR brought us a new version on their headers - I looked at and said "it's cracked". ATR snatches it back says no it isn't and hands it back. I hand it to the Ohio State welding engineer in the club sitting next to me, he looks at it and says "its cracked".

No, YOU are cracked.

I should add that I have an original ATR swaybar sitting in the corner - curious if it is built better than the current variations.

He took the header back from from The Ohio State welding engineer and let out a frustrated "dammmmmit" like he new exactly who was responsible.
