Thinking of long tubes now... Best bang for the buck. Out of the long tubes for a 346ci who is possibly going SC or big solid roller in the future when I change setups.. What will give me the best bang for the buck.. Dynatechs, Grotts, FLP's, or Hookers... I need reasons why.. Whats too big and what has not been dyno tested...?

Re: Thinking of long tubes now... Best bang for the buck. If you want cats , y-pipe , gaskets all
extenders for the 02 sensors the I suggest
SLP, if you car is lowered then step up
to FLP.. Hookers are nice but I dont think
you get cats and y-pipe.
you can see what comes in the SLP kit here.

Re: Thinking of long tubes now... Best bang for the buck. SLP's have horrible ground clearance and don't make any more power than Macs...
FLP's work, but go with a custom y-pipe. Their 2.5 inch y SUCKS..
Hookers don't make any more power than Macs.
Dynatechs are an overkill for a 346 motor. Seen a couple of people lose power with them compared to a normal longtube setup..
Grotts would be the best choice. ALL the fast cars in my area run Grotts, and all make excellent power for their mods. Tons of fast cars on this site run Grotts, and also make the dyno #'s to prove the flow of the header. Grott+ custom Y would be the way to go for sure...

Re: Thinking of long tubes now... Best bang for the buck. I am happy with my Hookers, but if I had it to do over again, I would go with Grot's. I really wish I had researched a little more rather than getting in a hurry.
I have the Mufflex y-pipe, and although the craftmanship is great, the driver's side pipe bangs on the floorboard with bumps. I'm gonna have to get it welded. Also it has several exhaust leaks where the clamps aren't doing their job. The part where it y's to a single is off center in the driveshaft tunnel, and nothing will clamp onto the 4" outlet because they made it just a little too big.

Re: Thinking of long tubes now... Best bang for the buck. Love the Grot's!!! <img border="0" alt="[hail]" title="" src="graemlins/gr_hail.gif" /> If you have a big motor or put the juice to it the 1 7/8 are going to be awesome. If you don't go with the 1 3/4. ARE, Thunder Racing and Quick Time Performance can get them. Some may have them in stock, others may wait for group purchases. I got mine from ARE with my heads and cam among other things.
I'm going to put the juice to the car in the spring and possibly convert to a 427 solid roller. The year after I may add the Pro/Charger or put some more juice to it. No idea yet, but I went with a big header so I can grow into it quickly. I will say on my current setup I am loosing some torque with the big tubes. That should be made up very soon!
Here's what the Grot's did to my Corsa. Simply mean!!

Re: Thinking of long tubes now... Best bang for the buck. Well No Dynos# yet, in my opinion the Macs w/OP are great. They sound very nice too. If your wondering how much it helped me out performance wise, The Mac Headers and 3:73 gears helped me out 7 tenths! I put them on at the same time so I dont know just exactly each helped, but I think the Macs played a big part in those 7 tenths.
Consider the Macs. For $550 bucks i got my headers with off road pipe, installation, 02's etc.

Re: Thinking of long tubes now... Best bang for the buck. I have MACs.. I am looking to upgrade.. I am leaning toward the Grotts... I wish someone would provide proof that changing to Grotts from MACs is a worthwhile investment. So far all I hear are guesses and what should happen..
I can shift faster than you.

Re: Thinking of long tubes now... Best bang for the buck. Vince, I went from MACs to Grots. I have a dyno sheet, but I need to scan it in. It was worth ~4rwhp at peak, but the area under the curve was slightly better. This was with my old B1/stock heads setup.

Re: Thinking of long tubes now... Best bang for the buck. "Dynatechs are an overkill for a 346 motor. Seen a couple of people lose power with them compared to a normal longtube setup.."
Damian, i see you're point and i respect it so please dont take this the wrong way but um, i'm going to go ahead and have to um.. disagree with you on this one.. um yeah... ;D
what kind of cam specs were these losses on? if you're talking about a straight duration cam (i.e. 222/222), on the stepped 1-7/8" headers, i can see it but, generally you cant go wrong with a larger primary size. however, on a split duration (say, 226/236) the bigger primary i necessicary. Smokey Yunic, Lingenfelter, Pat musi, ect... have been doing this for years.. these seasoned racers know that bigger tube headers make more power N/A, but especially on N20, & SC setups. but it's all in the tuning/ parts combo.
bang for my buck, Dynatech LT's 429 shipped from LS1speed.com, slip collectors (got mine from Stahl headers 49.00 ea shipped) so for cheaper than a set of coated hookers, you get an excellent coated header with no emissions B.S. to boot. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: Thinking of long tubes now... Best bang for the buck. Vince you are only going to see 3-4RWHP at peak. Not worth it IMO for a grand of cash. You may pick up around 6-8RWTQ under 3K rpm but that is it. I wouldn't waste my money on them. If you want more power get rid of that restrictive catback and run a highflow muffler. That will give you more than 1K set of headers.
Then you will pick up about 8RWHP peak in street trim vs having to open the cutout <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Cheers,
Chris

Re: Thinking of long tubes now... Best bang for the buck. Jason I would love to see that dyno sheet comparison. Chris I see your point. My thing is noise level.. I know I have to give up something, but I do not want to disrespect my neighbors.. I will continue investigating.

Re: Thinking of long tubes now... Best bang for the buck. Dynatechs are not overkill. The stepped header may be but the straight 1.75" is just fine. I personally prefer the grots since they have picked up power and torque over every header I have seen compared.
