I'm looking into getting some Comptech headers, but have one concern. I heard from a few people told me that if I put headers on my car, it will dramatically change the sound of my exhaust and make the car extremely loud and obnoxious. Is this true? Will I lose the greatt sound of my Greddy's if I put headers on? Any info/help will be greatly appreciated!!

Thanks!~

 

Can't speak for aftermarket exhaust, but with a stock exhaust, headers barely make a noticable difference in sound besides maybe being a slightly deeper tone, but definitely not louder. Hope that helps.

 

i got my Comptech headers put on this week and while my car is noticeably louder, i wouldn't say it's extremely louder or obnoxious. i actually like the deeper tone better

 

So its just a little bit deeper/throatier. . .hmm, I could actually use a little bit of that lol. . .it could compensate for my Icebox not being as loud as the AEM and other intakes!!!

 

You will barely notice it. Actually, you may be the only the notices it. The Evo II will definitely over power the sound of the headers. I have both CT headers and the Evo II catback.

 

do they sound good together at least?

 

They sound very good together. The only difference you may tell is that the exhaust note becomes slightly deeper.

PM me if you need a Comptech header.

 

i like the way the car sounds now, but i have the Comptech exhaust. i would assume your exhaust is louder though.

 

i got my headers from Excellerate...great guy

 

PM SENT!!!!!

 

CL's and TL's sound great with just the headers and stock exhaust... it's when you add mufflers to the mix where you get things a little too loud...

There's a reason that Comptech sells a quiet tip insert for their axle back exhaust

You'll be fine with just the headers...

 

 

I'll second this...when I put on my headers it really didn't make a louder tone at all. The exhaust was still quiet.

 

agreed. the headers with a stock exhaust shouldn't really be noticable but i do notice them a bit with the comptech exhaust but its at an acceptable level

 

headers + comptech axleback sounds decent i suppose too then.

 

How about the power gains. . .Are they noticeable??

 

power gains are VERY noticeable. reset ur ecu by unplugging ur battery for a few minutes (remember to reset your auto driver-side window. in manual).

as for sound, it's not louder.. its more like deeper. i have stock and sounds a bit more towards the g35 exhaust.

 

I'm sure it wont sound bad with the EVO II's. . .they could actually use a little more bass/deepness to them!

 

CT headers + CT bpibe + stock cans =

 

i have the ct headers and the rt cat combo. the gains from the headers alone are noticeable. with the rt cat my my rpm runs 200 or so lower then before. i'm assuming it's because there is less restriction. at any rate the headers will give you noticeable gains.

 

There is no noise difference if you stick to stock mufflers and CT headers. This is my present set up on my CL-S. It's sweet!!!

 

Well I guess i'll just have to wait and see how they sound with the Greddy's. . .If I like it, and it's not loud and annoying I'll go with it. . .If I dont, I still got my stock exhaust so I'll just throw that back on, sell the greddy's and get a few hundred bucks towards the rims I plan on gettin!!

 

I put on the CT headers on first and later added the CT exhaust. The headers barely changed the stock sound, but added a lot of performance... most noticable after 4K RPM. The exhaust adds a better exhaust note, but no performance. The stock CLS exhaust is free flowing.

When i first got the CT exhaust it sounded really good. After a year it is noticably louder... not sure of you will experience this with the Greddy.

With an auto you may notice a highwy "drone". I found that pretty annoying on my last CL as it was right at highway cruising speed (about 70). My 6MT is geared differentlly so I don't notice it at all.

 

Yeah, I never experienced the drone in my 6 Speed with the EVO's. . .I doubt it'll sound bad/loud with the headers. . .and if it does it's probably gunna sound meann as hell and that is deff. not a problem for me!!

 

Oops... didn't notice that you had a 6MT. You will have no problem... in fact you will love the sound!

On another topic... how is your traction? Wheel hop user to be a big problem for me with the 6MT till I installed an engine damper... you may want to give this some thought.

 

wheel hop sucksssssss!!!! lol Everytime I do a burnout it feels like im going over 100 speed bumps one after another. . .what damper did you go with? Im not too familiar with that

 

Here is the thread...

my pics are on page 3 (it is a pretty lengthy thread). I got my damper on ebay.

 

Sorry to go off topic here, but can u PM me where to find these dampers. . .And please tell me what the best one is with the least vibrations. . .I understand from reading your posts that you have a horrible noice from your power steering pump and I deff. dont want that. . .My engine makes enough annoying noises as is!! lol

Thanks~

 

... good luck

 

hey guys im new to acurazine i've had my ss cls auto for about 3 years it's bone stock i purchased CT Headers i got a few questions, installing the headers would i need to change my catalyic converter or would the stock cat be fine?

 

No need to touch the Catalytic converter...

 

Bolts right up to your stock cat. You'll be fine.

 

Thanks guys How about the Stock Exsaust should leave that alone aswell, this performance shop told me i should leave the stock exsaust because its already a free flow what should i do??

 

yes, changing the exhaust is more for the sound/look than performance. That is if you're NA.
