Pacesetter Cat-Back Exhaust System?

[Realrider88]

I have not seen too much talk about this monza whole cat back exhuast, i just have a couple nooby questions....

first id like to say
I have a 2004 Grand Am SE1 with a 3400 in it and CAI


All the questions are mainly based on this
1999-2005 Grand Am Pacesetter Cat-Back Exhaust System

http://www.mpracing.org/store/index....&productId=324


1. Isnt there a cat back exhaust stock on his car? Is there a need to replace it that will give significant H.P.? it sounds nice with mandel bends...

2. This is the cheapest cat back that i have seen, is it worth it? Are their cheaper better ones?

3. What is the way to go with pipe sizing? 2.5in 2.25in?

4. Is it just best to go with a performance muffler?

5. Since i have an SE1 with a 3400 can you use the one linked above? It has dual exhuasts and the stock one on the car has only one.

6. Is the monza bolt on or weld? (Considering i have a SE with one exhaust pipe)

7. Will it harm the engine or tranny at all?

8. How does it sound?

9. Is this a better idea than the monza?
It says u get some 50 HP with it.... sounds scammy but not a scammy website

1. Isnt there a cat back exhaust stock on his car? Is there a need to replace it that will give significant H.P.?

If you have a CAI, the cat back system with dual outlets will enhance the overall performance of the car.

2. This is the cheapest cat back that i have seen, is it worth it? Are their cheaper better ones?

Cheapest cat back I've seen. Most other cat backs are made of stainless. This one is not, only the tips.

3. What is the way to go with pipe sizing? 2.5in 2.25in?

2.5 will give you more top end speed. 2.25 will give you better low end
response.

4. Is it just best to go with a performance muffler?

Matter of preference, many members are quit pleased with their custom
systems. I would say alot of members use 2.5 pipe and a Magnaflow 80
mufler with no resinator.

5. Since i have an SE1 with a 3400 can you use the one linked above? It has dual exhuasts and the stock one on the car has only one.

It will fit.

6. Is the monza bolt on or weld? (Considering i have a SE with one exhaust pipe)

Not sure and dosen't matter.

7. Will it harm the engine or tranny at all?

No.

8. How does it sound?

Better than stock?

9. Is this a better idea than the monza?

Shop and compare.


Hope this helps in making a decision.....

[Realrider88]

but what do you think about the number 9. question.. and the product that is link? about the man that claims 50HP

[Ralph]

you links are not valid it looks like you just copied and pasted shorten links out of a forum already. If I had to guess what you linked being exhaust related it would be the SS headers which are not part of the cat-back. Not having a 3400 myself I find 50 hp hard to believe but who knows its possible depending on how restrictive the stock manifolds are.

[Realrider88]

If i were to buy the 1999-2005 Grand Am Pacesetter Cat-Back Exhaust System

http://www.mpracing.org/store/index.php?act=viewProd&productId=324

is it a good idea to remove the resinator from it if it has one?

a little off topic... is there anything you need to buy to put a bigger throttle body on such as the 62mm(i belive stock is about 54mm) such as CAI or headers,? anything?

and what will it do?

[Ralph]

lets your engine breath more. Normally people upgrade the TB while upgrading the intake manifolds and/or PnP the heads.

The Pacesetter has no resonator, any pictures with it are stock pictures that don't represent the actual setup. It's a bolt up install, but it can be welded. Any cat-back (other than cans) should sound better, deeper and louder.
04redgt1, it's a Flowmaster 80, just to let you know. There are Magnaflows used by some, but idk the model number.
About the price, basically you gotta pay to play with some of this stuff. Sure, the Pacesetter may be $100 cheaper than making your own with stainless, but if you keep the car and the aluminized rots out you'll need to spend more to replace it.

[04REDGT1]

Sorry about that Blackhawk guess I got my mufflers crossed.:lol:

[Realrider88]

oh so what your saying is your dont really need the resinator anyway, but i dont understand why you say stock pictures dont represent the actual thing/ set up, are you talking about the link? And does that matter that it only comes with one muffler and not two?

[Ryan625]

it should only come with one muffler. the muffler goes in the middle of the rear of the car and two pipes come out of it on both ends to the tips. I ordered this same setup from summitracing, but it never came. They claimed it was from the manufacture that didnt have it readily availible. Im not sure if mp racing has this set up in stock or not, but you might wanna contact them before you order and then wait forever for it to come from pacesetter.

[Realrider88]

The Pacesetter has no resonator,


Blackhawk i think you are wrong on that one about no resinator

There's no resonator on that system .... ;)

[Realrider88]

yea i ened up getting the Grand Am Pacesetter Cat-Back Exhaust System and true CAI for just under $500, is that good?

[Blackhawk]

I see two tips, three pipes, and a muffler. No resonator.
The stock picture I'm talking about is listed on some sites of a single muffler/dual tip combo with a resonator, it's for a Ford Probe or something, they were given the wrong pic.

[gt00]

Personally , i wouldn't buy that system because it's not stainless ( as was mentioned ) but if that's of no importance to you , or you're not keeping the car that long , then go for it ... ;)

[Blackhawk]

And it's really not that expensive to go stainless, it was maybe $20 more to run stainless tubing than 12-14ga aluminized tubing on my car.

[jackpot]

what are you guys opinion about loss of low end torque going with 2.5''

lets say average-mid high, highway driving, around 2000-2500 rpm, would there be loss in that bandwidth?

does the increase in power/torque with 2.5'' only apply to say 3000-5000 rpm? do you see any in the 2000+ or do you see loss in the 2000's?

does 2.25'' give increase in low end torque compared to stock GT exhaust or 2''? say around 1500-2500rpm, or would you have better torque without

thanks

peace

[Blackhawk]

There was a small loss in low end for me, nothing too big though. It really pulls at 2500 or 3000.

[boost21]

I don't really like the muffler but overall am pleased...heres some pictures i took when I first got mine.

No resonator for those wondering

[Realrider88]

boost why dont you like the muffler,? and is it a good idea to replace a catalytic converter?

[Blackhawk]

How many miles on the car? GM is required to service your car for 8 years/100,000 miles or something like that. After that then you need to think about it.

I just liked the sound of my flowmaster i had on it before. One of the Welds broke so i just got a new cat back. One day I will probibly swap them.
