Magnaflow Exhaust help (what i need)

[98SilverGS-T]

I went down to a local muffler shop and the guy wants $200 for full stainless steel piping from the cat all the way back to the muffler/TIP...he said my car just has resonators and that those can just be removed...
My question is, shouldn't there be a muffler like half way through the car and THEN the TIP?.....I want to go 2.5 only because i heard 3" will give me boost creep...is this true? I'd appreciate any opinions on what to do for my exhaust setup

Thanks for your help

Cat---piping-----muffler------------------exhaust tip Shouldn't that be the right way?

No you don't want any resonators or pre-mufflers.

Your muffler should be right before the tip.. and it should be your only muffler

Alright sounds good...Thanks for the help
So what about the boost creep? Will i get any w/ a 3" exhaust?

 

[L2RTSiAWD]

Not normally with a cat-back. Boost creep normally becomes more apparent when you get a 3inch DP>

 

[98SilverGS-T]

Sounds good...I planned on getting a DP and hi-flow CAT but I don't wanna deal w/ boost creep so I think I'll just get the cat-back....
They told me they could make me a custom full IC pipe also, should i use 2.5" or 3" for the ic pipe? either one is the same price...

 

[L2RTSiAWD]

2.5. 3inch is over-kill on IC pipes unless you are a full drag car.

hey man i got a magnaflow #18204 (3'" into 4") and it is immediately before the tip - asctually the tip is the part of the muffler and the hole going into the tip is 4" - i'm running a 2.5" high flow cat then 3" all the way through the muffler and i had no resonators or anything like that. custom mandrel bent by a local shop. i attached the bill - notice he only charged me 100 to bend and weld it!!!

btw i have absolutely no creep and i'm gonna have him bend me 2.5 ic pipes and a 2.5" dp!

#18204

I couldn't find that muffler on magnaflow.com.......Is your tip the "mirror finish" muffler or is it the "oval body" type muffler?

thanks lr2 for the info.

 

[98SilverGS-T]

$456 for the full catback!?...that's kinda expensive if you ask me....The guy wants 200 even but if i want a different muffler he's gonna add like $50...I think i'm going 3" then.....how does your magnaflow sound?

 

[red91GSX]

well he wrote down 18204 but looking at the site i think it's the 14828 - maybe he's dyslexic - either way he did a hell of a job and it's nice and throaty not like that mommy boy's lil civic up the street.

check out my pics

#14843 - 2.25" Inlet, 4" Diam. Tip, Single Wall, Staight Cut 4" Length

 

[red91GSX]

the oinly prob with this muffler is it's not avail in 3" inlet and they'll have a helluva hard time stretching 2.25" out to 3.25 without cracking to allow your main pipe from the cat if you go 3"

 

[98SilverGS-T]

Aw this sucks... i was thinking maybe this one

With the tip of the other exhaust...I want the round type canister cause i wanna slant it like the N1 sorta...

 

[jim97gst]

You could look at 14828. It has the tip like you like and a 3" inlet, but it's oval.

I have it on my car and really like it. Oval shape plus no slant up equals much less chance of scraping that pretty muffler on a speed bump.

If you really like the N1 look but don't want to pay $200, there are a lot of companies that sell N1 knockoffs for about the same price as the Magnaflows (~$100).

 

[98SilverGS-T]

Jim thanks a lot...i was looking at that oval one too...I think i might just get that one....So yours is just 3" piping from the CAT to the muffler/tip correct? How does your exhaust sound? does it get really loud when you get on it in?

 

[jim97gst]

My exhaust is 3" O2 eliminator turbo back from RNR with internal dump and a high flow cat. I got it from RNR with no muffler and had that magnaflow welded on locally. It's pretty loud at WOT but not ridiculous. I like the sound. It's a little loud cruising at 70-75, but again, totally bearable. You can get a silencer like the N1 has for any of the magnaflows with a single wall tip for about $30. I haven't bothered to get one. If I did a lot of long trips in the car I might. With just a catback, yours will be a good bit quieter.

cool..thanks for the info JIM...does anyone know the difference between the "stainless steel round" mufflers and the oval "mirror finish" mufflers (as in sound)
