Opinions on exhaust
 

I am going to be totally re doing the exhaust on the GTA. Here is my plan and the only part that I haven't decided on is what cat-back to go with.

Hooker 2055 Emissions headers with Y-pipe
Catco 3 Inch in 3 Inch out flanged cat.

Here are the three exhaust Systems I have narrowed it down to

Magnaflow: http://www.summitracing.com/parts/MPE-16829/

Flowmaster: http://www.summitracing.com/parts/FLO-17233/

Borla: http://www.summitracing.com/parts/BOR-14888/

I want the Borla but the price tag is large so that why the other two are in consideration. If I get the magnaflow or the flowmaster it leaves room for me to get a set of runners to go with this set up now. If I buy the Borla the runners will have to wait for the winter.

Just looking for some opinions to kind or narrow it down to one so I can shorten up my summit wish list lol

I have the Flowmaster exhaust on my 87. I don't think I would buy it again. Fitment was not the best and they use the old style exhaust clamps which makes it a real pain to take apart. I would go with one of the other kits you listed.

Your gta should have dual cats right?

buy Ted's Borla

my third gen has hooker emmisions headers, high flow cat and the hooker cat back... i have a sound clip some where

Negative. Dual Cat's was an extra. And that really wouldn't matter because I am replacing the Y-pipe and going with a different cat set up

Thought about it but I want to put all new stuff on the car. Just my preference right now

Damn you, you just added a 4th choice to the mix. Is that 3 inch at the converter flange? You don't happen to have a part number do you? Summit has it listed as fits single cat models but doesn't specify which size

uhh bought it like 7 years ago lol i have no idea and havent really driven or seen it in 2 years, i also have a cut out welded in before the cat. i know the cat is 3in and the catback is 3in


looking thru summit i think i found what i have

obviously its not the same as a ls1
but i dont like borla. the adjustable is cool but its raspy even with a resonator

That's why I like it

Borla adjustable on my LT1 is pure sex

I'm a fan of hooker 2055s into the magnaflow. Loud when you want it to be, low rumble at idle/coasting. That's what I'm saving for.

you get over it very quickly
imo

OK so I placed my large summit order this morning and got my free shipping :banana:

here is what I got
Hooker Headers 2055
Borla Adjustable
Catco 3 inch In 3 Inch Out
Accell shorty spark plugs
Taylor 90* boot wires
Spark Plug wire boot protectors

Runners can wait for the winter or until i stumble accross a used set.

Great list, except for this!

I agree. I do not know if they are a necessary mod though. If they are not, ditch them.

NGK makes shorter plugs if you need the clearance.

I bought them as a just in case.

Yes, I use those in my Z. My old headers needed them.

You use Accels or the NGK's?

I always had problems with those cats breaking up and coming apart. The only aftermarket cat I found to last was the ODBII compliant ones from Magnaflow. But they are much more expensive than the Catco.

How about a Mufflex 3.5" system for your car? You can choose the muffler to suit your sound tastes...

I actually heard they were pretty good. How long were they on the cars before they broke up?

Run a true duel setup.

Less than a year.

You can and others have done so successfully, but the dual pipes are a pain to route and add a lot of weight vs. a single pipe.

He has a stock 305 right now. Both those options seem to be a bit overkill.
