Make sure you get headers with ceramic coating. I found a penny size hole in front of the rear o2 sensor. I got the powder coated Hookers about 3-4 years ago. Now I got to replace them.

Choco my 1 7/8 bolt on combo made more power and went quicker all around E.T. and MPH than your 1 3/4 bolt on set up. I would call that real proof. Oh yeah and I was on a stock tune with stock tires too.

think I would gain much switching to 1 7/8 from 1 3/4 jethots with a 383 and some spray?

Really? What's my rwhp/rwtq, ET and trap?

Where did you run the car at? What was the temperature and humidity? Are all our mods exactly the same? How much gas did you have? How new were your tires, what brand were they and what psi were they? How much gas did you have in the tank? What was your race weight? What octane fuel? What brand of fuel? What % ethanol was in the fuel? What DA?

I could ask you about a million more questions, but you haven't even provided anything backing any of that up, so...

My car bone stock trapped 115 mph with a full tank of gas in July. Call me a liar on the internet. I swear it happened. My buddy saw it, too.

What I can tell you is your numbers aren't all that impressive in your signature for an M6 with a larger heads and cam package, especially if it's through a 10-bolt.

Thank you. I'm glad you finally realized it. You be the qtp nut hanger and I'll be the tsp nut hanger. Until someone makes a good enough dyno comparison to satisfy you. lol

ChocoTaco369

QTP vs. Pacesetter on a H/C car. No other changes. That's why I'm not surprised TSP could outperform extremely outdated (and tiny) Pacesetters. I've been satisfied for awhile.

I'm sorry that wasn't on a completely stock motor, and there are too many unknown variables. I refuse to accept that it's anything but marketing. lol Sound familiar?

ChocoTaco369

You're trying to say 1 7/8" headers are better by comparing them to a 1 3/4" header with a totally different design. That's meaningless.

All I'm trying to say is Pacesetters leave a lot on the table. On my dyno, it was just a header swap between Pacesetters and QTP's. QTP's blew them out of the water. I've proven my point without a doubt. You haven't proven anything, except that I'm wasting my time trying to help people that don't want to listen. Like I said, do what you want. It's not my car and it's not my money.

I'm sorry but you haven't proven anything but the fact that the qtps were better on whatever setup that is than the pacesetters. Get off your holier than thou pedestal already. The funny thing about this is that I haven't even been really pushing the larger size. I just said I have them and they are great for me. It's when I asked you to present some real evidence to support your claims and refute the current posted evidence is when you got your panties in a bunch and started taking offense. So until you produce your kooks 1 3/4 vs kooks 1 7/8, on a stock 346, back to back, dyno sheet, I don't think we have anything more to talk about. Thanks, it was amusing.

Sorry I'm not. I decided to stay with my gmmg catback. But here is my sound clip. I don't think you'll be disappointed.


and in a race:

GMMP chambered exhaust has veryvery poor flow numbers, probably the worst performance catback you can put on your car.


but it sounds good.

yeah choco your 13 sec car is gonna beat up on all the cars on the street

https://ls1tech.com/forums/eastern-m...otune-rpm.html 13.064 in the 1/4

get over yourself please

ChocoTaco369

Yea? I have no tires and a 2.2 60 foot. 30,000 miles never rotated. It's a low-mid 12 second trap. That's all that matters.

ChocoTaco369

The QTP's made significantly more power than the Pacesetters all over the curve, yet it shows nothing Whatever helps you sleep at night. Guys like you make your opposition look smart

I voted 1 3/4 but with an MS4 1 7/8 should balance it out to be better... i have 1 7/8 on only bolt ons and it lacks torque down low but rockets up top.. id say 2-3 more HP uptop 10-20 less lb-ft down low- same torque as 1 3/4 above 3500 RPM though... i figure with heads and cam (3+ years down the road) the 1 7/8 will be more suitable

Out of curiosity where did you come up with that conclusion that it has poor flow numbers? It couldnt be worse than a flowmaster..

The 1 7/8" have me interested for my 402 with L92 Heads, then again I think I may see a decent gain with that.

After reading this entire thread, I have decided I am going to purchase 1 13/16 headers... for my 305
