Re: Grot headers? Grotyohann Headers from Grotyohann Motorsports.
Roger Grotyohann is the owner.
They are 1 3/4 inch full length (longtube) headers. (He also makes them with 1 7/8 inch primaries but those are for big cubed engines).
They are the best performing headers on the market for the F-body.
They are also the hardest to find.
Your best bet is to call around to every vendor you know and ask if they have any in stock for your specific year vehicle.

Roger used to supply Random tech cats, but now uses Carsounds on the y-pipe.

Grots @ More Performance Inc.
BTW, My car is lowered and had plenty of clearance when I ran the cats, sounds like an install issue the other guy had with the Y-Pipe.

Re: Grot headers? Re my post about the Grot y-pipe. My car is lowered 3/4" and clearance is 3 3/16" exactly. Agostino did the install and it was done correctly. Unfortunately, the driver's side cat attaches at the lowest point, and the clamp projects downward. If not for that, there would be another 1/2" clearance, but if the clamp was not positioned that way it would bump the floor. I mentioned this to Nick, and he said it could be fault of Grotyohann now using Carsound cats rather than Random Techs. After paying my muffler guy to go over the crappy welds, before the install, it looks like I'll have to pay him again to try to remedy the situation. The headers are great but the y-pipe sucks for sure.

Re: Grot headers? The headers are awesome <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" /> but DO NOT BUY the Y-PIPE. It is poorly designed and the assembly is even worse. <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />
I have the 1 7/8 and they are fine for stock cubes H&C motors spinning into the high 6000s. I'll trade a few pounds of torque below 3500 for more HP above 5500.
With an ORP, ground clearance looks good to me, but I haven't measured.

Re: Grot headers? I also have the Grot 1 7/8 headers and their y-pipe. While I agree that they aren't as good as the headers, I seriouosly doubt that it would cost you any hp, a y-pipe is a pretty simple designm it's not rocket science. The only thing I think itit's kinda a pain to install but other than that I think it's fine. Just my .02.

Re: Grot headers? I would find a shop that has a mandrel bender and have them make you a pipe. For the price of the Y-Pipe you can probably have it made. If you are near LG motorsports, they'll take care of you.
As far as the Y-pipe not costing HP, I don't believe it. One side enters into the pipe at a 30* angle flows into the side of the pipe (because he doesn't use a collector <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> ) and metal tubing extends partially into the flow where they are welded together. The Y-Pipe is totally ghetto. <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />

Re: Grot headers? kobwo... god only knows why, but the dyno tests keep showing it.. the SLP's don't seem to be putting down the power.... only things I can think are the numbers of bends they use, and I heard they have a smaller y-pipe... but I'm going from memory on that one.

I stand by it, because its dyno and track proven, so I don't have to prove it. Many people before me already have. Ask the ppl that are at the top of the N/A and F/I track times lists what type of headers they are running. The majority will say Grots.
To answer Kobwo's question. "Tuned Length" is something they say to sell their product. As people have said before, SLP's are the "spaghetti headers". Bottom line is, more bends in the header pipes = less horsepower. Look at a pair of Grots in person and you'll see how beautifully made they are. You simply can't make headers any better.

Re: Grot headers? Am i going wrong with the FLP's at least when you get thoe FLP's you get offroad pipes cats and a y pipe and they seem to be good quality header.DO you get alot of power from these? and does the Grots have this stuff with them?
