Have SLP high flow cats and x pipe now, with pypes muffler delete. It's very loud. Will headers make it to loud? Because there is a point to where it's to loud

Try riding in a car with open longtube headers. My ears felt like they were bleeding and I have pype bomb muffler deletes too so I'm used to some noise

It's not so much peak horsepower that you get from long tubes. It's a torque curve that comes in lower and is flatter.dyno number disappoint but the test drive afterwards more than makes up for it

^^^This........ My 07 with full kooks exhaust,CAI and 93 race tune pulled 298whp but after the exhaust and tune install it was a blast to drive and did wonders for the butt dyno. The 4.10s also played a big part in the ol butt dyno. For me it wasn't so much the #s the car put down but the driving experience. It gave me a **** eatin grin that I couldn't wipe off my face.

87 tune, O/R X and intake/tune made 320 on a friends car. I believe he also has the stock dyno. I'll check to post.

Also,

05-10 Dyno around 260+ consistently. Intake and tunes have also consistently shown 20-35 WHP gains depending on octane. Obviously 93 being the best.

LTs have shown up to 40 for a S/C car and around 20 for a tuned n/a car.

300WHP is EASILY achieved in an S197. 320+ is where the hump gets taller to overcome.

4.10s also kill peak HP numbers.

Re: Headers

For every car that pulls 318/320 with those mods there is gonna be another one that didn't. All dyno are gonna read different and y'all know that. Besides it just a dyno and just a #. I could tell you I have a 12" unit but can I prove it or do I know how to use it is the question.

Ok, so the one that didn't is wrong?

Many before and afters show the net gain.

I think I'm going to go with shorty headers. That way I don't have to change anything else. Shorties will fit without any problems. I like pypes products and are wry reasonable. I'm gonna go with pypes shorty headers

Don't waste your money, the stock manifolds flow just as good as shorty's. Go long tube or stay stock.

SCREW that noise.
Shorty headers are a complete waste of time. you see barely any gains and look like a 'tard when people ask what headers you're running.
Get ARH (American Racing Headers), Kooks, or Pacesetter.
Longtubes or nothing!

BBK has a nice set: LT's with high flow cat x pipe for about a G. If you can't do it yourself you are looking at about $550 to $650 in labor. If you want an off road x it's about $200 less.

Yeah, but it won't work with long tubes. Totally different set up.
If you want to keep that set up then stay with the stock manifolds. Shorty's will be a waste of money. You won't even notice any power gains that you get if any.

Unless you plan on changing heads or supercharging you won't gain much. I changed mine to the FRPP 62 MM and didn't gain enough to notice. I've heard people say that they got a good increase but I didn't. So I say save your money, the stock TB works fine for stock heads.

So to get good gains I will have to drop big money into heads for the throttle body to work right? Can long tubes work with what I have if mechanic cuts mid pipe right?

I'm putting down just over 300 with CAI, tune and LT headers. So I guess it depends what you are looking for. I'm supercharging soon so I'm not doing any more mods until I see what I'm at when my sc is in. I don't want to go over 500 HP because that's about all the stock block can handle. I'm Installing a Roush R2300 phase one which should get me right around 475 to 500.

The thing with throttle bodies is that your MAF only allows so much air through. I want to say we have two 55mm butterflies to make 110mm total area. That's a whole lot more than the stock MAF can provide.
Upgrading a throttle body isn't needed on a stock motor.
You don't need to be sucking thousands of litres of air/hour unless you're making a lot of power.
Throttle bodies don't really make a big difference until you NEED to suck that much air due to a well-modded motor or FI.
